Opfindelsen angår en kombihane til anvendelse i rørmalkeanlæg i forbindelse med tilkobling af v malkesæt til en mælkeledning og samtidig til en vakuumledning som angivet I indledningen t3 krav 1. En sådan kombihane kendes fra WO-A1-95/32614.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a combi tap for use in pipe milking systems in connection with connection of v milking kits to a milk line and at the same time to a vacuum line as set out in the preamble of claim 1. Such combi tap is known from WO-A1-95 / 32614.

5 Denne kendte kombihane har imidlertid den meget betydelige ulempe, at der kræves en stor præcision fra malkerens side, når åbner-delen påsættes ventilhus-defen, idet et tragtformet spor I ventilhus-delen skal rammes. Ved afkobling må desuden et låsehåndtag på åbner-delen aktiveres med fingrene, dvs. en kombineret klem-træk-bevægelse. Alt dette komplicerer arbejdsgangen for malkeren, som ønsker hurtigt og nemt at kunne påsætte og aftage en kombi-10 hane.However, this known combi cock has the very considerable disadvantage that a high precision is required on the part of the milker when the opener part is applied to the valve housing defect, as a funnel-shaped groove in the valve housing part must be hit. When decoupling, a locking lever on the opener part must also be activated with the fingers, ie. a combined clamp-pull movement. All this complicates the workflow of the milker, who wants to quickly and easily put on and remove a combi-10 cock.

En anden stor ulempe ved denne kendte hane er et dårligt hygiejneniveau. Mælkesjatter eller •dråber, som uundgåeligt drypper fra åbner-delen ved frakoblingen, drypper ned langs indfølingssporet for åbner-delen. Og disse mælkerester, der hurtigt inficeres af mikroorganismer eller 15 sågar fluer, edderkopper o.l., føres ved næste indføring af åbner-delen let med ned i mælkerøret med forhøjede kimtal til følge. Det bemærkes bl.a., at nævnte patentskrift anviser en særlig pakning, som angiveligt forhindrer indsugning af kontamineret luft til mælkeledningen. Men netop denne pakning med aiie dens krinkelkroge er et ganske glimrende medium for mikroorganismer og umulig at gøre ren.Another major disadvantage of this well-known rooster is a poor level of hygiene. Milk caps or drops, which inevitably drip from the opener part at the disconnection, drip down along the feeler groove for the opener part. And these milk remnants, which are quickly infected by microorganisms or even flies, spiders and the like, are easily brought into the milk tube with elevated germ numbers at the next introduction of the opener part. It should be noted, inter alia, that said patent specification provides a special seal which allegedly prevents suction of contaminated air into the milk conduit. But this particular package with all its nooks and crannies is a pretty excellent medium for microorganisms and impossible to clean.

Endvidere er denne kendte kombihane meget kompliceret, idet den består af mange enkeltdele.Furthermore, this known combi cock is very complicated in that it consists of many individual parts.

Dette har også betydning for den lethed, hvormed man kan udskifte pakninger og andre dele, der eksempelvis udsættes for stor slitage. Det er i denne kendte kombihane meget vanskeligt . for ikke at sige umuligt for malkeren selv at komme til at udskifte f.eks. pakninger.This also has an impact on the ease with which one can replace gaskets and other parts, for example, which are subject to excessive wear. It is very difficult in this known combi rooster. so as not to say impossible for the dairyman himself to replace eg. gaskets.

Endelig har denne kendte hane kun en begrænset kapacitet, idet den eksempelvis ikke kan anvendes til samtidig malkning af f.eks. to køer under overholdelse af ISO-normeme.Finally, this known cock has only a limited capacity, for example it cannot be used for simultaneous milking of e.g. two cows in compliance with ISO standards.

GB-A1-955.760 anviser en kombihane omfattende en ventilhus-del og en åbner-del og kun et 30 ventilelement i form af et glidespjæld, der ved forskydning frem og tilbage åbner og lukker for adgang tn både mælke- og vakuumledningen. En pulsator er monteret på åbner-delen. Abner-delen kan tages helt af, og ventilhus-delen efterlades da med gildespjældet dækkende de to åbninger. Ved påsætning af åbner-delen skal dels en opretstående flange pé glidespjældet ramme præcist ned i en modsvarende udfræsning i åbner-delens forkant, og dels skat åbner-35 delen ramme korrekt ind i et spor, der er opadtil begrænset ved begge sider. Åbning og lukning sker altså ved en enkelt forskydningsbevægelse, men der kræves også her en meget stor præcision for at sammenkoble åbner-del og ventilhus-del korrekt. Denne kendte kombihane er beregnet på mælke- og vakuumledninger, der er anbragt i samme vandrette plan.GB-A1-955,760 discloses a combi valve comprising a valve body portion and an opener portion and only a valve element in the form of a sliding damper, which, when displaced reciprocally, opens and closes for access to both the milk and vacuum lines. A pulsator is mounted on the opener part. The opener part can be completely removed and the valve body part is then left with the throttle cover covering the two openings. When applying the opener part, an upright flange on the slider must frame precisely into a corresponding cut at the leading edge of the opener, and partly treasure the opener part correctly into a groove which is limited upwards on both sides. Opening and closing is thus done with a single displacement movement, but also here a very high precision is required to connect the opener part and valve body part correctly. This known combi tap is intended for milk and vacuum lines placed in the same horizontal plane.

2 DK 173139 B1 US-A-4,261.291 anviser en kombihane af en helt anden type beregnet på tilkobling til en mælkeledning og en vakuumledning, hvor mælkeledningen ligger inde i vakuumledningen. Ved hjælp af et særligt udformet ventilhus opnås, at åbningen for vakuumledningen i tilkoblingsområdet ligger lodret over åbningen til mælkeledningen. Kun et ventilelemenl. nemlig et glide-5 spjæld, dækker de to åbninger, der desuden normalt er dækket af et låg. Når tilkobling af et malkesæt ønskes, vippes låget væk, glidespjældet forskydes manuelt, hvorved åbningerne frilægges, og et ikke-vlst forbindelseselement til malkesættet indføres i åbningerne. Denne kendte kombihane er meget omstændelig at betjene og er kompliceret at tilpasse de ledningssystemer, man benytter i dag.US-A-4,261,291 discloses a combi tap of a completely different type intended for connection to a milk line and a vacuum line where the milk line lies within the vacuum line. By means of a specially designed valve housing, it is achieved that the opening for the vacuum line in the connection area lies vertically above the opening for the milk line. Only one valve element. namely a slide-5 damper, covers the two openings, which are additionally normally covered by a lid. When coupling of a milking kit is desired, the lid is tilted away, the slider is manually displaced thereby exposing the openings and a non-welded connecting element to the milking set is inserted into the openings. This well-known combi tap is very cumbersome to operate and is complicated to adapt to the wiring systems used today.

10 DE-A1-27 05 323 og DE-A1-26 37117 anviseren kombihane med en ventilhus-del og en åbnerdel men kun et ventilelement I form af et glidespjæld, der normalt dækker både mælkelednings-og vakuumledningsåbningen. I DE-A1-27 05 323 indføres en åbner-del i spor, der er opad ta afgrænset af en længdegående flange, og åbner-delen har modsvarende omvendt L-formede 15 flanger (et indgreb af typen fjer-not), der skal anbringes præcist i sporet. Desuden skal et koblingselement på åbner-delen bringes I Indgreb med et modsvarende koblingselement på glidespjældet Først herefter kan åbner-delen forskydes i sporet, hvorved der skaffes adgang ti de to ledninger, i DE-A1-26 37117 har glidespjældet to koblingselementer for modsvarende koblingselementer på åbner-delen. Når disse koblingselementer er bragt i indgreb, benyttes 20 åbner-delen til at forskyde glidespjældet. I begge disse kendte kombihaner kræves megen præcision ved betjeningen.10 DE-A1-27 05 323 and DE-A1-26 37117 indicate combi cock with a valve body part and an opener part but only one valve element in the form of a sliding valve which normally covers both the milk conduit and the vacuum line opening. In DE-A1-27 05 323, an opener portion is inserted into grooves bounded upwardly by a longitudinal flange and the opener portion has correspondingly inverted L-shaped flanges (a spring-notch type engagement) to be placed precisely in the groove. In addition, a coupling element on the opener part must be engaged with a corresponding coupling element on the slider. Only then can the opener part be displaced in the groove, thereby providing access to the two wires. on the opener section. When these coupling elements are engaged, the opener portion is used to displace the slider. In both of these known combi males, much precision is required in the operation.

Dansk patent nr. 98596 anviser en kombihane med en ventilhus-del og en åbner-del og kun et ventilelement i form af et pakningsorgan, der kan forskydes under til- og afdækning af åbninger 25 til mælke- og vakuumledningeme. Forskydningen bevirkes af en pladeformet del, som indføres og forskydes I et spor I ventilhus-deien, hvilket spor ved siderne er opadtil afgrænset (fjer-not-forbindelse). Når den ønskede forskydning er opnået, sættes nogle rømipler på den pladeformede del (eller aftages), og disse forbindes til malkesættet. Atter en meget kompliceret og præcisionskrævende betjening.Danish Patent No. 98596 discloses a combi cock with a valve housing part and an opener part and only a valve element in the form of a packing means which can be displaced during covering and covering openings 25 for the milk and vacuum lines. The displacement is effected by a plate-shaped portion which is inserted and displaced into a groove in the valve housing portion, which groove at the sides is delimited upwards (feather-not connection). When the desired displacement is achieved, some creams are applied to (or removed) the plate-shaped portion and connected to the milking set. Again a very complicated and precise operation.

30 DE-A1-40 03 367 og DE-C1-42 40 521 anviser mælkehaner, der også benytter et princip med forskydning af et glidespjæld. Sporet herfor er tragtformet, hhv. af typen fjer-not, dvs. opadta afgrænset i begge tilfælde. Dansk patent nr. 96324 anviser en mælkehane, hvor en åbner-del forskydes og derefter drejes i en svalehalenot. Svensk patent nr. 170 120 anviser en hane til 35 tilkobling til en enkelt ledning, f.eks. en mælkeledning. Et stempelformet ventilelement dækker normalt åbningen i kraft af en ijederpåvirkning. En rørformet åbner-del indføres i et spor, der er opadtil afgrænset og desuden forsynet med hak, som gør at åbner-delen kun kan indføres i den korrekte stilling. Ved afkobling skal en låseanordning desuden deaktiveres.30 DE-A1-40 03 367 and DE-C1-42 40 521 disclose milk cocks which also apply a principle of displacement of a sliding damper. The groove for this is funnel-shaped, respectively. of the feather-note type, viz. upward bounded in both cases. Danish Patent No. 96324 discloses a milk cock in which an opener part is displaced and then rotated in a dovetail note. Swedish patent no. 170 120 discloses a tap for connection to a single wire, e.g. a milk line. A piston-shaped valve member usually covers the opening by virtue of a spring action. A tubular opener portion is inserted into a groove that is bounded upwardly and additionally provided with notches which allow the opener portion to be inserted only in the correct position. When decoupling, a locking device must also be deactivated.

Endvidere findes på markedet kombihaner af mærket Fullwood® fra firmaet Fullwood og Uni-Combihane® fra firmaet SAC.Furthermore, there are combi males of the brand Fullwood® from the company Fullwood and Uni-Combihane® from the company SAC.

Fullwood® kombihanens første ventilelement er ikke et glidespjæld men en stålkugle, som er 5 ophængt i en holder, der kan dreje om en akse i mælkeledningens længderetning, og denne holder med kugle drejes væk fra åbningen, når en åbner med en åbnemekanisme i form af en bøjet mælkerørdel med omgivende plade Indføres ved forskydning i et spor i form af to parallelle, over for hinanden beliggende noter I ventilhus-delen (pladen glider I noterne og skubber til kuglen). Sporet er altså opadtil afgrænset med de ulemper i henseende til betjeningen, som er 10 anført ovenfor. Fullwood® kombihanen består endvidere af utrolig mange enkeltdele, heraf ikke mindre end fire bevægelige dele. Hygiejneniveauet I denne kendte kombihane er heller ikke tilfredsstillende, ligesom den ikke kan anvendes ti samtidig malkning af mere end en ko under overholdelse af ISO-normerne.The first valve element of the Fullwood® combi tap is not a slider but a steel ball, which is suspended in a holder which can rotate about an axis in the longitudinal direction of the milk line, and this holder with ball is rotated away from the opening when opening with an opening mechanism in the form of a bent milk tube part with surrounding plate Inserted by displacement in a groove in the form of two parallel, opposite grooves in the valve body portion (the plate slides into the grooves and pushes to the ball). Thus, the track is bounded upwards with the disadvantages in respect of the operation mentioned above. The Fullwood® combination cock also consists of an incredible number of individual parts, of which no less than four moving parts. The level of hygiene in this well-known combi cock is also not satisfactory, nor can it be used for simultaneous milking of more than one cow in compliance with ISO standards.

15 Ventilhus-delen af den kendte kombihane af mærket UniCombihane® har et fjederbelastet glideorgan, som dækker åbningerne til vakuum- og mælkeledningender. Dette giideorgan forskydes ved hjælp af en åbner-del, som Indføres i et opadtil afgrænset svalehalespor og fastlåses ved drejning. Ulemperne ved denne kendte kombihane er endnu en gang den store præcision, som er nødvendig før al ramme svalehalesporet rigtigt. Desuden kan man komme til at 20 låse åbner-delen "for tidligt.” Endelig kan heller ikke denne kendte kombihane leve op til ISO-normerne ved samtidig malkning af to køer.15 The valve body portion of the known uniCombihane® combi tap has a spring-loaded slider which covers the openings for vacuum and milk line ends. This guide means is displaced by means of an opener part which is inserted into an upwardly defined dovetail groove and locked by rotation. The disadvantages of this well-known combi cock are once again the great precision needed before all the dovetail groove hits correctly. In addition, 20 may lock the opener part "too soon." Finally, this well-known combination cock also cannot meet the ISO standards when simultaneously milking two cows.

Sammenfattende har de kendte kombihaner en ergonomisk uhensigtsmæssig betjening, ofte sammensat af både forskydnings og vride-/drejebevægelser. De er desuden uforholdsmæssigt 25 vanskelige at betjene, idet et bestemt spor skal rammes meget præcist. Endvidere er de kompliceret opbygget med mange enkeltdele, og udskiftning af reservedele er vanskelig, ligesom montering og service i øvrigt. Hygiejnen er også dårlig på grund af uhensigtsmæssig udformning. Endelig er deres kapacitet begrænset i forhold til ISO-normemes krav. Specielt kan ingen af de kendte kombihaner overholde ISO-normemes krav ved samtidig påsætning af mere end 30 et, nærmere bestemt to. malkesæt, dvs. til samtidig malkning af mere end en ko eller andet malkekvæg/-dyr.In summary, the known combi males have an ergonomically inappropriate operation, often composed of both shear and twist / turn movements. They are also disproportionately difficult to operate, with a particular track having to be hit very precisely. Furthermore, they are complicated with many individual parts, and replacement of spare parts is difficult, as is assembly and service in general. Hygiene is also poor due to inappropriate design. Finally, their capacity is limited to the requirements of ISO standards. In particular, none of the known combi males can meet the requirements of the ISO standards when simultaneously applying more than 30 one, more specifically two. milking kits, ie for the simultaneous milking of more than one cow or other dairy animal / animal.

Disse ulemper er elimineret med kombihanen ifølge opfindelsen, og endda på overraskende enkel, funktionsvenlig og effektiv vis.These disadvantages are eliminated with the combi male of the invention, and even surprisingly simple, functional and efficient.

Med hensyn til den hert anvendte terminologi, og specielt også vedrørende kravenes terminologi, gælder følgende: 4 DK 173139 B1With regard to the terminology used here, and especially with regard to the terminology of the claims, the following applies: 4 DK 173139 B1

Ved "åbning" forstås et bul, som tillader væske eller luft at passere. Åbningens tværsnit behøver ikke være cirkulærtBy "opening" is meant a bulb which allows fluid or air to pass. The opening cross-section need not be circular

Ved betegnelsen "kanal* forstås generelt blot et hulrum, uanset hvilket tværsnit og hvilken 5 længde eller aksial dimension. Der er ikke nødvendigvis i denne vending underforstået en mulighed for gennemgående passage af væske eller luft. Specielt gælder om den i kravet førstnævnte kanal, i hvilken i en såkaldt anden position et andet ventilelement bevæges Ind, at denne kanal ikke åbner mulighed for gennemgående passage af væske eller luft. Nævnte kanal kan blot være en udsparing eller ringdannelse omkring den tilhørende åbning. Vigtigt er blot, at 10 den kan rumme det andet ventilelement eller en del heraf, således at en ønsket kommunikation mellem en anden kanal og åbningen kan etableres. Den nævnte anden kanal er dog af den type, som giver mulighed for gennemgående passage.The term "duct * is generally understood to mean only a cavity, regardless of the cross-section and any length or axial dimension. In this reversal, there is not necessarily implied a possibility of passage of liquid or air. which in a so-called second position moves another valve element In that this duct does not allow for the passage of liquid or air, said duct can merely be a recess or annulus around the associated opening, it is important that it can accommodate it a second valve element or part thereof so that a desired communication between another channel and the opening can be established, however, said second channel is of the type which allows for passage through.

Ved betegnelsen "kommunikere” om forholdet mellem to åbninger eller to kanaler eller en 15 åbning og en kanal forstås, at der kan passere væske eller luft fra den ene til den anden. Der behøver altså blot være et ganske lille overlap mellem de respektive åbninger/kanaler. Denne situation benævnes undertiden også som en Ί det mindste delvist frilagt* åbning/kanal. I de fleste tilfælde vil man dog ønske en total overlapning af de to åbninger, således at den mindste åbning er helt frilagt.The term "communicating" about the relationship between two openings or two passages or an opening and a passageway means that liquid or air can pass from one to the other, so there is only a very small overlap between the respective openings / This situation is sometimes also referred to as a Ί at least partially exposed * opening / channel, but in most cases a total overlap of the two openings is desired, so that the smallest opening is completely exposed.

2020

Ved betegnelsen "glidespjæld" forstås egentlig blot en glider, dvs. et legeme, som er beregnet på at udføre en forskydningsbevægelse, en glidebevægelse eller en translatorisk bevægelse. Fortrinsvis en positivt styret eller tvangsstyret bevægelse, dvs. i et særligt spor.By the term "sliding damper" is meant simply a slider, ie. a body which is intended to perform a shear, sliding or translational movement. Preferably a positively controlled or forced movement, i.e. in a special track.

25 Giidespjældet behøver altså ikke være pladeformet som vist på tegningen. Det kan også være f.eks. cylindrisk eller af mere kompliceret eller sammensat form.Thus, the guide damper need not be plate-shaped as shown in the drawing. It can also be e.g. cylindrical or of more complicated or compound shape.

Ved betegnelsen "et andet ventilelement* forstås et legeme af en hvilken som helst form og hult eller massivt, som generelt er Indrettet tfl at kunne dække og afdække en åbning under 30 indvirkning af en (ekstern) åbnemekanisme.By the term "another valve element * is meant a body of any shape and hollow or solid which is generally arranged to cover and cover an opening under the influence of an (external) opening mechanism.

På tegningen er vist el andet ventilelement i form af en (massiv) kugle, der kan skubbes op i en sidekanal ved indføring af en åbnemekanisme, hvorfra den vil falde ned, tilbage til den åbningen dækkende position, under indvirkning af tyngdekraften og vakuum, når åbnemekanismen atter 35 fjernes.The drawing shows another valve element in the form of a (solid) ball which can be pushed up into a side channel by introducing an opening mechanism, from which it will fall down, back to the opening covering position, under the influence of gravity and vacuum when the opening mechanism is again removed.

5 DK 173139 B1 ' Men dette andet ventilelement kan akkurat ligeså vel være en ellipsoide. en halvkugle, en keglestub eller en kegle, en terning eller andet multieder - eller have sammensat form.But this second valve element may just as well be an ellipsoid. a hemisphere, a cone stub or cone, a cube or other multieder - or having compound form.

Og den anden kanal behøver ikke være opadrettel eder have en opadrettet komposant. således 5 at tyngdekraften udnyttes til returnering eller udløsning af elementets tilbagefald. Oer kunne også være tale om f.eks. et element, der er fjederpåvirket i retning mod den dækkende position, men kan føres ind i en kanal, måske i form af en udsparing dier et hak i åbningen, ved hjælp af en dbnemekanisme, hvorfra fjederkraften bevirker dets tilbagefald, når åbnemekanismen atter tjemes.And the second channel does not have to be upside down to have an upside down component. so that gravity is utilized to return or trigger the relapse of the element. Oer could also be talking about e.g. an element which is spring-loaded in the direction of the covering position, but can be inserted into a channel, perhaps in the form of a recess, which engages a notch in the opening, by means of a opening mechanism, from which the spring force causes its recoil as the opening mechanism is re-energized.

Dette understreger, at den førstnævnte kanal ikke behøver være en kanal i traditionel forstand, men også blot kan være en udsparing eller et hulrum.This emphasizes that the former channel need not be a channel in the traditional sense, but can also simply be a recess or cavity.

Skønt de gennemgående, separate passager i åbner-delen er defineret som "mælkerør," hhv.Although the through-going, separate passages in the opener section are defined as "milk pipes," respectively.

15 'Vakuumrør," menes hermed blot gennemgående passager i åbneren for mælk og vakuum. Det behøver ikke være faste rør, men kan eksempelvis være fleksible forbindelser i form af slanger.15 "Vacuum tubes," by this is meant only through passages in the opener for milk and vacuum. It need not be solid tubes, but may, for example, be flexible connections in the form of hoses.

Et "spor" (som leder til glidespjældet) er defineret som forløbende i en længderetning og i det mindste delvist afgrænset af en bundflade. En mulig længderetning er vist på tegningen. Når 20 vendingen "i det mindste delvist afgrænset af en bundflade" bruges, menes hermed dels. at denne bundflade ikke behøver være en plan flade - den kan f.eks. have huller og/eller fremspring og/eller relief- eller andet mønster - og dels at den Ikke behøver være udstrakt i hele længderetningen frem til glidespjældet Bundfladen er blot en eller anden form for afgrænsning "nedadtil," som forhindrer gennemfald af en åbner-del, der føres ad sporet.A "groove" (leading to the slider) is defined as a longitudinal course and at least partially bounded by a bottom surface. A possible longitudinal direction is shown in the drawing. When the phrase "at least partially bounded by a bottom surface" is used, this is partly meant. that this bottom surface need not be a flat surface - it can e.g. have holes and / or projections and / or relief or other pattern - and partly that it does not have to be extended in the entire lengthwise direction until the sliding damper The bottom surface is just some form of "downward" demarcation, which prevents the passage of an opener part which is led along the track.

25 Når det anføres, at sporet forløber i længderetningen, menes hermed, at en væsentlig del af dette spors bundflade forløber overvejende i viste længderetning. Bundfladen definerer altså en afgrænsning af sporet i en første tværretning til nævnte længderetning.When it is stated that the groove extends longitudinally, it is meant that a substantial portion of the bottom surface of this groove extends predominantly in the longitudinal direction shown. Thus, the bottom surface defines a boundary of the groove in a first transverse direction to said longitudinal direction.

30 En forreste ende er generelt defineret som vendende mod højre på tegningen, og tilsvarende en bageste ende vendende mod venstre. Dette tjener kun ti) forklaring af kombihanen ifølge opfindelsen. I virkeligheden behøver højre ende ikke at være "forrest" og vice versa. Tilsvarende gælder op/ned og fremad/tilbage. der umiddelbart er brugt under henvisning til tegningen, men I virkeligheden kan være vendt om.A front end is generally defined as facing right in the drawing, and correspondingly a rear end facing left. This only serves to explain the combi male of the invention. In reality, the right end doesn't have to be "up front" and vice versa. Similarly, up / down and forward / backward apply. which is immediately used with reference to the drawing, but may in fact be reversed.

3535

Ved den anviste udformning er sporet "åbent", der er ingen tragt, rillle, not, hul eller lignende, som man skal være påpasselig med at ramme.In the design provided, the groove is "open", there is no funnel, groove, groove, hole or the like which one must be careful to hit.

6 DK 173139 B1 Når det anføres, at sporet ved den forreste ende umiddelbart før glidespjældet har en opsamlingsrende, forstås ved "opsamlingsrende" blot en fordybning i forhold til bundfladens hovedplan eller sporets forskydningsplan eller glideplan. Formålet med nævnte opsamlingsrende er at opsamle spildt mælk og føre det væk fra forskydningsplanet eller glideplanet for åbner-delen.6 DK 173139 B1 When it is stated that the groove at the front end immediately before the sliding damper has a collecting ring, "collecting ring" is meant only a recess in relation to the main plane of the bottom surface or the displacement plane or sliding plane of the groove. The purpose of said collecting duct is to collect wasted milk and move it away from the shear plane or sliding plane of the opener portion.

Ventilhus-delen 21 sammenspændes med bøjlen 26 omkring et stykke af mælkeledningen 11. Mælkeledningen er i form af rør med en væg. der omgiver et indre hulrum, og i væggen er boret en opadvendende åbning 18 (fig. 5B). Denne åbning 18 kommunikerer med en åbning 28 med cirkulært tværsnit øverst i fladen 24, hvilken åbning 28 er gennemgående i retningen 10 op-ned CD. Et cylindrisk fremspring 29 rager et lide stykke nedad i forhold til indersiden af fladen 24. Fremspringets 29 nederste endeflade er rundet svarende til formen på ydervæggen af mælkeledningen 11. En pakning 30 er beregnet på anbringelse omkring dette fremspring 29 til sikring af tæt anlæg mod mælkeledningen (pakningen 30 er vist på lig. 8).The valve body portion 21 is clamped with the bracket 26 about a portion of the milk conduit 11. The milk conduit is in the form of tubes with a wall. surrounding an inner cavity and an upwardly opening opening 18 (Fig. 5B) is drilled into the wall. This aperture 18 communicates with an aperture 28 of circular cross-section at the top of the surface 24, which aperture 28 is continuous in the direction 10 upside down CD. A cylindrical projection 29 protrudes downwardly from the inside of the surface 24. The lower end surface of the projection 29 is rounded in accordance with the shape of the outer wall of the milk conduit 11. A seal 30 is intended to be placed around this projection 29 to ensure a dense contact with the milk conduit (package 30 is shown at equ. 8).

15 En ringnot 31 i en øvre endeflade 39 af den halvcylinderformede flade 24 omgiver den cirkulære åbning 28. Denne ringnot 31 er beregnet på at optage en pakningsring 32 (se også fig. 7).A ring groove 31 in an upper end surface 39 of the semi-cylindrical surface 24 surrounds the circular opening 28. This ring groove 31 is intended to receive a gasket ring 32 (see also Fig. 7).

Et glidespjæld 33, der er nærmest pladeformet, er anbragt på fladen 39, således at det kan forskydes I længderetningen fra en første position, hvor det dækker åbningen 28, der har for-20 bindelse til mælkeledningens 11 indre hulrum, til en endeposition vist i fig. 3.1 denne endeposition støder en forreste stopansats 34 på glidespjældet 33 mod et opadragende fremspring 35 ved den forreste ende af ventilhus-delen. Og i denne endeposition er fri adgang via åbningen 28 ned til mælkeledningens 11 indre hulrum. Stopansatsen 34 har form som en nedadbøjet endedel, se også fig. 7. Føringen eller forskydningen af glidespjældet 33 på fladen 39 beskrives 25 nærmere under omtalen af fig. 9. Under forskydningen af glidespjældet 33 frem og tabage over åbningen 28 tætner pakningsringen 32 mod en nedadvendende flade af glidespjældet 33.A slider 33, which is closest to plate-shaped, is arranged on the surface 39 so that it can be longitudinally displaced from a first position where it covers the opening 28 which connects to the inner cavity of the milk conduit 11 to an end position shown in FIG. FIG. 3.1 this end position bears a front stop 34 on the slider 33 against an upwardly projecting 35 at the front end of the valve body portion. And in this end position, free access is via the opening 28 down to the inner cavity of the milk conduit 11. Stop stop 34 is in the form of a downwardly bent end portion, see also FIG. 7. The guide or displacement of the slider 33 on the surface 39 is described in greater detail during the discussion of FIG. 9. During the displacement of the slider 33 forward and tab over the opening 28, the seal ring 32 seals against a downwardly facing surface of the slider 33.

Ved sin bageste ende har glidespjældet 33 et første koblingselement 98 i form af en vulst 36, der nærmest har form som et omvendt U. Denne vulst 36 er dog bøjet lidt fremad, i retning mod 30 den forreste stopansats 34, hvorved fremkommer en tværgående spalte eller et gab 38, hvis formål skal beskrives senere. Vulsten er ved to endedele i den tværgående retning forsynet med flappe 37.At its rear end, the slider 33 has a first coupling element 98 in the form of a bead 36, which is almost in the form of an inverted U. However, this bead 36 is bent slightly forward, towards the front stop 30, thereby producing a transverse slot. or a gap 38, the purpose of which will be described later. The bead is provided with flap 37 at two end portions in the transverse direction.

Ventilhus-delen 21 har ved sin anden ende, benævnt den bageste ende, et midterstykke 87, der 35 forbinder de to sidevægge 22, 23. Centralt på dette midterstykke 67 og ved en øvre endedel heraf er anbragt en bagudragende stopansats 50, hvis funktion vil blive beskrevet senere. Ligeledes centralt på midterstykket 87, men ved en nedre endedel heraf, er der en åbning 40 med cirkulært tværsnit Denne åbning 40 har nærmest form som et rørstykke og forløber et 9 DK 173139 B1 stykke ind i midterstykket 87, nærmere bestemt 1 længderetningen for ventilhus-delen 21. Et stykke inde i midterstykket 87 afgrenes fra den rørformede åbning 40 to andre rørstykker vinkelret herpå, nemlig en opadgående kanal 41 og en nedadgående kanal 42, der begge udmunder til det fri. Rørstykkeme eller kanalerne 40, 41, 42 danner altså et T-stykke indvendigt i 5 midterstykket 87. Den nedadgående kanal 42 har mindre diameter end den opadgående kanal 41. Et andet ventilelement 97 i form af en kugle 44 med større diameter end den nedadgående kanal 42 er indført i retningen oppefra og ned gennem den opadgående kanal 41 og ligger an mod en pakningsring 45 anbragt i en tilsvarende udsparing i midterstykket 87 ved overgangen fra åbningen 40 GI den nedadgående kanal 42. Denne pakningsring 45 udgør et sæde 10 for kuglen 44, og denne bageste del af ventilhus-delen 21 omfatter altså en kugleventQ-del. Diameteren af åbningen 40 er mindre end diameteren af kuglen 44, mens diameteren af den opadgående kanal 41 er større end eller lig diameteren af kugien 44. Når kuglen 44 er indført, lukkes åbningen t3 det fri af den opadgående kanal 41 med en plade 46, idet en pakningsring 51 anbringes I en ringnot i midterstykket 87 omgivende denne åbning til det fri. således at der 15 bliver tæt lukket ned til kuglen 44. Pladen 46 skrues fast med en skrue 48, idet en Gisvarende skruegang 49 forefindes i midterstykkets 87 øvre, bageste del.The valve body portion 21 has at its other end, referred to as the rear end, a center piece 87 connecting 35 the two side walls 22, 23. Centrally located on this center piece 67 and at an upper end portion thereof is a rearwardly extending stop shoulder 50, the function of which will be will be described later. Also centrally on the center piece 87, but at a lower end portion thereof, there is an opening 40 of circular cross-section. This opening 40 is almost like a pipe piece and extends a piece into the center piece 87, more specifically in the longitudinal direction of the valve body. the portion 21. A piece within the center piece 87 is branched from the tubular opening 40 two other tubes perpendicular thereto, namely, an upward passage 41 and a downward passage 42, both of which open to the outside. Thus, the tubes or channels 40, 41, 42 form a tee inside the center piece 87. The downward passage 42 is smaller in diameter than the upward passage 41. Another valve member 97 in the form of a ball 44 is larger in diameter than the downward passage. 42 is inserted in the direction from top to bottom through the upward passage 41 and abuts against a gasket ring 45 arranged in a corresponding recess in the middle piece 87 at the transition from the opening 40 G1 to the downward passage 42. This gasket ring 45 constitutes a seat 10 for the ball 44. and this rear portion of the valve body portion 21 thus comprises a ball valve Q portion. The diameter of the aperture 40 is smaller than the diameter of the sphere 44, while the diameter of the upward channel 41 is greater than or equal to the diameter of the sphere 44. When the sphere 44 is inserted, the opening t3 is closed to the free of the upward channel 41 by a plate 46. a sealing ring 51 being placed in a ring groove in the center piece 87 surrounding this opening for free. so that 15 is sealed tightly to the ball 44. The plate 46 is screwed with a screw 48, with a threaded screw thread 49 being present in the upper, rear portion of the center piece 87.

Den nedadgående kanal 42 danner en rørformet forlængelse nedadtil af midterstykket 87, hvilken rørformet forlængelse har en rørvæg 43. Gennem den nedadgående kanal 42 etableres 20 forbindelse GI vakuumledningen 15, som det vil blive beskrevet nærmere under omtalen af fig. 5A.The downward passage 42 forms a tubular extension downwardly of the center piece 87 which has a tubular extension 43. Through the downward passage 42, connection GI of the vacuum conduit 15 is established, as will be described in detail in the discussion of FIG. 5A.

Fig. 6 viser en bagesle endedel af ventilhus-delen 21 og viser, sammen med fig. 7.1 detaljer udformningen af sporet 75 for åbner-delens 60 plade 65. Sporet 75 er ubegrænset opadtO og defineres af glideflader 53,54,56 og 57.FIG. 6 shows a rear end portion of the valve body portion 21 and, together with FIG. 7.1 details the design of the groove 75 for the plate 65 of the opener portion 60. The groove 75 is unlimited upward 0 and is defined by sliding surfaces 53,54,56 and 57.

5 På fig. 6 ser man, at sidevæggene 22, 23 I ventilhus-delen hver har et indadvendende førings-fremspring 52 med en øvre glideflade 53. Disse glideflader 53 er nærmest parallelle med en overkant af sidevæggene 22, 23 og med glidespjældets 33 forskydningsplan. En overkant af den opad skrånende glideflade 57 ses at flugte med glideflademe 53. Man ser også på fig. 6 en nedre kant 93 af den opad skrånende glideflade 57. En bundflade 55 af sporet 75 er beregnet 10 på i det mindste delvist at dækkes af pladen 46 (ikke vist på fig. 6). Når pladen 46 er påsat bunddelen 55, flugter dens overkant med kanten 93.5 In FIG. 6, it is seen that the side walls 22, 23 in the valve body portion each have an inwardly directed guide projection 52 with an upper sliding surface 53. These sliding surfaces 53 are almost parallel to an upper edge of the side walls 22, 23 and with the shear plane of the sliding 33. An upper edge of the upwardly sloping sliding surface 57 is seen to align with the sliding surfaces 53. Referring also to FIG. 6 shows a lower edge 93 of the upwardly sloping sliding surface 57. A bottom surface 55 of the groove 75 is intended to be at least partially covered by the plate 46 (not shown in Fig. 6). When the plate 46 is attached to the bottom portion 55, its upper edge aligns with the edge 93.

Den ene sidevæg 23 af ventilhus-delen 21 er forsynet med et ekstra vægelement 90, som afgrænser et hulrum med en bagudrettet åbning 91 og en fremadrettet åbning 92. Dette hulrum 15 er beregnet på at rumme et elstik af hun-typen (se også fig. 8 og 9). idet stikket er tagængefigt gennem åbningen 91, og ledningen til elnettet føres ud gennem åbningen 92.One side wall 23 of the valve body portion 21 is provided with an additional wall element 90 defining a cavity having a rearward opening 91 and a forward opening 92. This cavity 15 is intended to accommodate a female-type electrical connector (see also FIG. 8 and 9). the plug being roof overhang through the opening 91 and the lead to the mains lead out through the opening 92.

Ved begge sidevægge overgår glidefladen 53. som jo var "parallel," ved en kant 94 i en næste glideflade 54, som skråner svagt nedad og overgår i en tredje glideflade 56. som fortsat skråner nedad under samme vinkel og ved kanten 93 overgår i den (fælles) opad skrånende glideflade 57.In FIG. 6 in combination with FIG. 7, and, moreover, of FIG. 8, it appears that ten each side wall 22, 23 each hear a sliding surface 53, 54 and 56, while the sliding surface 57 is common to the two spoon-20 walls. At both side walls, the sliding surface 53. which, after all, is "parallel," exits at an edge 94 of a next sliding surface 54, which slopes slightly downwards and passes into a third sliding surface 56. which continues to slope downwards at the same angle and at the edge 93 transitions into it. (common) upwardly sloping slide surface 57.

25 En bredde af sporet 75 (dimension I tværgående retning) kan defineres som afstanden mellem yderkanterne af de to sidevægges 22,23 respektive glideflader 53,54,56,57. Man ser af fig. 7. at sporets 75 bredde indsnævres ved overgangen mellem glideflademe 54 og 56. Formålet hermed beskrives nærmere nedenfor under funktionen af kombihanen.A width of the groove 75 (dimension in transverse direction) can be defined as the distance between the outer edges of the two side walls 22.23 and sliding surfaces 53,54,56,57, respectively. From FIG. 7. narrowing the width of the track 75 at the junction between the sliding surfaces 54 and 56. The purpose of this is described in more detail below during the operation of the combi cock.

30 De to glideflader 56 afgrænser mellem sig, I området nær den fælles glideflade 57, en flade 59, der skråner nedad i retning fra fladen 57 mod ventilhus-delens 21 bagende, og denne flade slutter I en nedadvendende åbning 58, hvori centralt er anbragt den med skruehul forsynede ansats 25 for skruen 27. Formålet hermed beskrives nærmere I det følgende.The two sliding surfaces 56 define, in the area near the common sliding surface 57, a surface 59 which slopes downwards in the direction from the surface 57 towards the rear of the valve body part 21, and this surface terminates in a downward opening 58, which is centrally arranged screw cap 25 for screw 27. The purpose of this is described in more detail below.

Glidespjældet 33 anbringes nu på ventilhus-delen 21, idet forenden af den ombukkede kant 85 anbringes i indgreb med bagenden af fremspringet 66 på ventilhus-delens 21 øvre flade 39 og forskydes fremad (fig. 9). Denne første del af forskydningen foregår lidt hindret på grund af spjældets forreste stopansats 34. Men når spjældets stopansats 34 kan smutte "ned på plads” 30 over en anlægsflade 95 (det sker I en position omtrent svarende til første position; fig. 5C). ja, så sker resten af spjældets fremadrettede forskydning ganske let og uhindret. Det er selvfølgelig kun I montagesituationen, at der er lidt prespasning. Når først spjældet sidder korrekt, kan det forskydes ganske let og frit mellem sine bevægelsesgrænser (se nærmere nedenfor). Herefter, når spjældet 33 er i den anden position, anbringes pakningsringen 32 i sin ringnot 31 omkring 35 åbningen 28.The slider 33 is now placed on the valve body portion 21, the front end of the folded edge 85 engaging with the rear end of the projection 66 on the upper surface 39 of the valve body portion 21 and displaced forwardly (Fig. 9). This first part of the displacement is slightly obstructed by the front stop stop 34 of the damper, but when the stop stop 34 of the damper can slip "down into place" 30 over a contact surface 95 (this occurs in a position approximately similar to the first position; Fig. 5C). yes, then the rest of the damper's forward displacement happens quite easily and unobstructed.Of course, it is only in the mounting situation that there is little pressure fit.Once the damper is seated properly, it can be moved quite easily and freely between its movement limits (see further below). when the damper 33 is in the second position, the gasket ring 32 is placed in its ring groove 31 about the opening 28.

Now, the bracket 26 is placed on the other side of the milk conduit 11 and clamped with the valve body portion 21 by means of the screw nut connection 27. 74. A conduit 111 from the central power supply is inserted through the aperture 92 and is electrically connected outside the aperture 91 to the female connector 110, which is subsequently inserted into the cavity surrounded by the additional wall element 90.

Oet bøjleformede element 77 forsynes ved den nedadvendende studs 78 med en pakning 30 og studsen 78 føres ned i hullet 19 i vakuumledningen 15. Det bøjleformede element 77 spændes fast til vakuumledningen 15 ved hjælp af spændebåndet 82 med tilhørende stilleskrue 83. Et 15 stykke gummislange 76 anbringes tæt omgivende ved sin nedre ende det bøjleformede elements 77 opadvendende rørstykke 79 og ved sin øvre ende rørvæggen 43 omgivende den nedadgående kanal 42 I ventilhus-delen. Nu er der etableret forbindelse mellem ventilhus-delen 21 og både vakuum- og mælkeledningen 15, hhv. 11.The shackle member 77 is provided at the downwardly facing stud 78 with a gasket 30 and the plug 78 is inserted into the hole 19 in the vacuum line 15. The shackle member 77 is clamped to the vacuum line 15 by the clamping belt 82 with associated adjusting screw 83. A 15 piece rubber hose 76 is placed close-up at its lower end, the upwardly extending pipe piece 79 of the hanger-shaped element 77 and at its upper end the pipe wall 43 surrounding the downward passage 42 in the valve body part. A connection has now been established between the valve body portion 21 and both the vacuum and milk conduit 15, respectively. 11th

20 I åbner-delen 60 indføres pakningsringen 88 omgivende vakuum-røret 62 fra dettes forreste ende og anbringes i anlæg mod en forreste sideflade af pladens 65 lodrette ben 72. Han-stikket 105 monteres på udvidelsen 101 af det lodrette ben 72 ved hjælp af skrue-fmøtrikforbindel-sen 104/107 (og forbindes elektrisk til eksempelvis pulsator og aftager).20 In the opener portion 60, the gasket ring 88 surrounding the vacuum tube 62 is inserted from its front end and is placed against a front side surface of the vertical leg 72 of the plate 65. The male plug 105 is mounted on the extension 101 of the vertical leg 72 by means of a screw. nut 104/107 (and is electrically connected to, for example, pulsator and taper).

25 Den beskrevne kombihane fungerer som følger I en udgangsposition dækker glidespjældet 33 åbningen 28, og kuglen 44 lukker i kraft af sin vægt og vakuum den nedadgående kanal 42. Abner-delen 60 "klaskes" nu på sit spor 75. Med "klaskes" hentydes til, at der kun stilles meget begrænsede krav til den præcision, der er 30 nødvendig for at ramme rigtigt ned I sporet 75. Ved betragtning af fig. 5, 7 og 8 vil man indse følgende: For det første er sporet 75 ikke overhovedet begrænset opadtil; der er f.eks. Ingen tragt eller lignende, som man skal stikke åbner-delen rigtigt ind i. Abner-delen kan indføres fra en hvilken som heist højde over ventilhus-delen.The described combi valve functions as follows. In a starting position, the slider 33 covers the opening 28 and the ball 44 closes downwardly by virtue of its weight and vacuum the downward channel 42. The Abner portion 60 is now "whacked" on its track 75. to impose very limited requirements on the precision required to strike right down the track 75. In view of FIG. 5, 7 and 8, one will realize the following: First, the track 75 is not at all restricted upward; there are e.g. No funnel or similar to which the opener part must be inserted properly. The opener part can be inserted from any height above the valve body part.

35 Til gengæld stilles der lidt krav til præcisionen I tværgående retning: Der skal man ramme rigtigt, idet sporets bredde som defineret af yderkanterne af de respektive sæt af glideflader 53, 53 og 54, 54 svarer omtrent til en bredde af det vandrette ben 71 for åbner-delens 60 plade 65. Men en vis styring af påsætningen af åbner-delen haves alligevel, da nemlig sidevæggene 22,23 har DK 173139 B1 16 opad fremstikkende øvre kanter ved denne bagende af ventilhus-delen. Skønt oprette har disse fremstikkende øvre kanter alligevel en slags tragtfunktion, idet godstykkelsen af sidevæggene aftager opadtil (se en markeringslinje 96 på fig. 3, under hvilken inderfladen af væggen 22 forløber lodret, og over hvilken samme inderflade forløber skrånende udad).35 On the other hand, there is little requirement for precision in the transverse direction: one must strike right, as the width of the track as defined by the outer edges of the respective sets of sliding surfaces 53, 53 and 54, 54 corresponds approximately to a width of the horizontal leg 71 for The plate 65 of the opener part 60. However, some control of the application of the opener part is nonetheless, since the side walls 22,23 have upwardly projecting upper edges at this rear end of the valve body part. Although erect, these protruding upper edges nevertheless have some sort of funnel function, with the thickness of the sidewalls decreasing upwards (see marking line 96 in Fig. 3, below which the inner surface of the wall 22 extends vertically and over which the same inner surface extends outwardly).

Med hensyn 13 under hvilken vinkel åbner-delen 60 indføres i sporet 75, er der store variationsmuligheder, der alle leder fil slutmålet, nemlig at sammenkoble pladen 65 på åbner-delen med glidespjældet 33 på ventil-husdelen. F.eks. kan åbner-delen indføres parallelt med glide-fladerne 53 og under anlæg mod disse. Men den kan også indføres i en vinkel på f.eks. 45* med 10 glideflademe 53 og under anlæg med disse. Eller analogt, men under en vinkel på 90*. Principielt endda i en vinkel større end 90*. skønt dette næppe har nogen praktisk relevans.With respect to 13, at which angle the opener portion 60 is inserted into the groove 75, there are large variation possibilities that all guide the final target, namely, to connect the plate 65 of the opener portion with the slider 33 on the valve housing portion. Eg. For example, the opener portion may be inserted parallel to the sliding surfaces 53 and during abutment thereof. But it can also be introduced at an angle of e.g. 45 * with 10 sliding surfaces 53 and under abutment with these. Or by analogy, but at an angle of 90 *. In principle, even at an angle greater than 90 *. although this hardly has any practical relevance.

Men ikke nok med det: Åbner-delen kan også indføres under alle de nævnte vinkler, men under anlæg mod en hvilken som helst af glideflademe 54 eller 56. Når der her tales om anlæg med glideflademe i en vinklet indføringsstilling, er det faktisk området omkring vulsten 66 på åbner-15 delens plade 65. der er i anlæg 1 starten af indføringsoperationen.But not only that: The opener part can also be inserted at any of the aforementioned angles, but under abutment against any of the sliding surfaces 54 or 56. When talking about abutment with the sliding surfaces in an angled insertion position, it is actually the area around bead 66 on opener 15 plate 65. which is in abutment 1 the start of the insertion operation.

Men altså ligegyldigt under hvilken vinkel man rammer sporet i starten af indføringsoperationen, sænkes efterfølgende åbner-delen og forskydes så I retningen fremad, hvorved i første omgang en nedadvendende flade af et forreste område af åbner-delen, navnlig området ved vulsten 66 20 automatisk får anlæg mod de nedadskrånende glideflader 54, 56, og på grund af den opadskrånende glideflade 57 tvangsstyres åbnerens plade 65 så I låsende indgreb med glidespjældets 33 omvendt-U-formede vuist 36. Denne position er i teksten beskrevet som den første position. Vulsten 36 på glidespjældet har ved sine ender en lille flap 37 med det formål at stabilisere åbner-delens vuist 66 mod sideværts vridninger I den låste tilstand. Afhængigt af hvor 25 i længderetningen, åbner-delen nedsættes i sporet, kan en Indledende forskydning af dens forreste del langs glideflademe 53 komme på tale, før det ovenfor omtalte anlæg mod glideflademe 54 osv, se fig. 5AHowever, no matter at what angle one strikes the groove at the start of the insertion operation, the opener portion is subsequently lowered and then displaced in the direction, thereby initially obtaining a downwardly facing face of an anterior region of the opener portion, in particular the area of the bead 66 20 abutment on the downwardly sliding surfaces 54, 56, and due to the upwardly sliding 57 the opener plate 65 is forced to lock in engagement with the inverted U-shaped fist 36 of the slider 33. This position is described in the text as the first position. The bead 36 of the slider has at its ends a small flap 37 for the purpose of stabilizing the opener portion 66 against lateral torsions in the locked condition. Depending on where 25 in the longitudinal direction, the opening portion is lowered in the groove, an Initial displacement of its front portion along the sliding surfaces 53 may be considered before the abovementioned abutment towards the sliding surfaces 54, etc., see fig. 5A

Ved fortsat forskydende påvirkning af åbner-delen I fremadgående retning, låses dennes 30 plade 65 fast vinkelmæssigt I forhold fil ventilhus-delen, nemlig i en stilling hvor dens to yderkanter nedadtil har anlæg mod hver sin glideflade 53 ved bagenden og ved forenden har anlæg mod hver sin, I samme plan som glideflademe 53 sig befindende, øvre glideflade omkring åbningen 28. Og ved denne fortsatte forskydning medbringes glidespjældet 33, glidende omkring fremspringene 86 på ventilhus-delen, se f.eks. fig. 5B.Upon continued displacement of the opener portion in the forward direction, its plate 65 is locked at an angular ratio with respect to the valve body portion, namely in a position where its two outer edges face downwardly on each sliding surface 53 at the rear end and at the front end abutment. each, In the same plane as the upper surface 53 of the sliding surfaces 53, is located about the opening 28. And in this continued displacement, the slider 33, sliding about the projections 86 on the valve body part, is brought, see e.g. FIG. 5B.

På vakuumsiden trænger åbner-delens vakuumrør 62, nærmere bestemt enden med pladen 70, ind i åbningen 40 og begynder at løfte kuglen 44 opad i den opadgående kanal, se også fig. 5B.On the vacuum side, the vacuum tube 62 of the opener portion, more specifically the end with the plate 70, penetrates into the opening 40 and begins to lift the ball 44 upwardly in the upward passage, see also FIG. 5B.

35 17 DK 173139 B1 I den såkaldte anden position som vist i fig. 5C er nu åbningen 1 mælkeledningen 18 lige under åbningen 26 i ventilhus-delen, og på vakuumsiden er kuglen 44 nu loftet op i sin øverste position, og åbningen 69 i vakuumrøret 62 er lige over åbningerne 42 etc. ned til åbningen 19 i vakuumledningen 15. I denne stilling er også den elektriske tilkobling sket, sammenlign med 5 fig. 9. Malkningen kan påbegyndes. I denne anden position ligger en Inderflade af åbner-delens lodrette ben 72 an mod stopansatsen 50 på ventilhus-delens bageste endeflade, og pakningsringen 88 har, rundt omkring vakuumrøret 62, tætnende anlæg mod samme Inderflade og ventShus-detens bageste endeflade.35 17 DK 173139 B1 In the so-called second position as shown in fig. 5C is now the opening 1 of the milk conduit 18 just below the opening 26 of the valve body portion, and on the vacuum side the ball 44 is now lofted into its upper position and the opening 69 of the vacuum tube 62 is just above the openings 42 etc. down to the opening 19 of the vacuum conduit 15 In this position, the electrical connection has also been made, as compared with FIG. 9. Milking can be started. In this second position, an inner face of the vertical leg 72 of the opener portion abuts against the stop shoulder 50 on the rear end face of the valve body member, and the gasket ring 88 has sealing abutment against the same inner face and the rear end face of the vent housing 62.

10 Efter afsluttet malkning føres åbner-delen ud af indgreb med ventilhus-delen faktisk som beskrevet ovenfor, bare i omvendt rækkefølge: Ved at trække 1 retningen bagud i åbner-delen og på grund af låseanordningen 89 mellem g lidespjæld og åbner-delen føres så glidespjældet atter tilbage, glidende omkring fremspringene 86. Når glidespjældets forreste stopansats 34 når anlægsfladen 95, stopper blbagebevægelsen af glidespjældet, og låseanordningen 89 frigøres.10 After milking is completed, the opener portion is removed from engagement with the valve body portion, as described above, in reverse only: By dragging 1 direction backward in the opener portion and due to the locking device 89 between the g slider and the opener portion, the slider returns, sliding around the projections 86. When the front stop 34 of the slider reaches the abutment surface 95, the flap movement of the slider stops and the locking device 89 is released.

15 dvs. vulsten 66 glider ud af den omvendt-U-formede vulst 36 på glidespjældet. Abner-delen 60 kan nu tages ud af sit spor 75 på lige så mange forskellige måder som beskrevet ovenfor - og de er alle lige gode.I.e. bead 66 slides out of the reverse U-shaped bead 36 on the slider. The Abner section 60 can now be taken off its track 75 in as many different ways as described above - and they are all equally good.

I en fordelagtig udførelsesform for kombihanen opnås, på grund af særlige træk ved sporet 75, 20 som vil blive beskrevet nærmere nedenfor, at uanset hvilken udtagningsvej man vælger for åbner-delen, vi eventuelle spildte mælkedråber eller -sjatter lande på et sted, hvor de Ingen skade gør.In an advantageous embodiment of the combi cock, due to special features of the groove 75, 20 which will be described in more detail below, it is achieved that no matter which withdrawal path is chosen for the opener portion, we possibly spilled milk drops or jars at a location where they No harm done.

Det er jo velkendt, at spildte mælkedråber er et fremragende næringsmedium for mikroorga-25 nismer, Insekter og lignende. Med andre ord danner sådanne spildte mælkedråber grobund for bl.a. bakterier, og derved opstår der risiko for, at bakteriekim og lignende overføres til mælkesystemet, f.eks. ved den næste indføring af åbner-delen.It is well known that spilled milk drops are an excellent nutrient medium for microorganisms, insects and the like. In other words, such spilled milk drops form a breeding ground for e.g. bacteria, thereby causing the risk of bacterial germs and the like being transferred to the milk system, e.g. at the next insertion of the opener section.

Men betragter man fig. 5B og forestiller sig, at åbner-delen nu er på vej bagud, så er der ganske 30 vist vakuum i mælkerøret 61, men alligevel vil en sjat mælk blive hængende i det sidste krumme stykke af dette rør og dryppe ned på ventilhus-delens 21 overside. Men på denne overside, altså umiddelbart bag åbningen 28, findes jo den nedadskrånende flade 59 afsluttende med hullet 58, og her vil den spildte mælk i de allerfleste tilfælde lande og simpelthen løbe væk.However, if you consider fig. 5B and assumes that the opener part is now on its way back, there is admittedly a vacuum in the milk tube 61, but still a saturated milk will hang in the last curved part of this tube and drip down on the valve body part 21 the upper side. But on this upper side, that is immediately behind the opening 28, the downward sloping surface 59 is found to end with the hole 58, and here in the vast majority of cases the spilled milk will land and simply run away.

Det vi altså ikke blive ført med op til åbningen 28, når åbner-delen næste gang føres hen over 35 dette område.Thus, we will not be led up to the opening 28 when the opener portion is next passed over this area.

18 DK 173139 B118 DK 173139 B1

Skulle mælkerøret 61 nu alligevel ikke være færdig med at dryppe, når åbningen 68 heri når hen til den bageste ende af sporet 75, så sker der heller ikke noget ved det. For, som det fremgår af Tig. 6, er sporets bundflade 55 jo forsænket i forhold til glidefladerne for pladen 65 hørende til åbner-delen. Ganske vist er pladen 46 ikke vist på fig. 6, men den når kun op til skilleplanet 93, 5 så der er stadig en forsænkning. Og mælk, der spildes ovenpå pladen 46. føres ikke med op til åbningen 28, for åbner-delens plade 65 glider ovenpå fladerne 53,54,56, der alle er forhøjede I forhold til midterpartiet.However, should the milk tube 61 not finish dripping when the opening 68 therein reaches the rear end of the groove 75, then nothing will happen. For, as shown by Tig. 6, the bottom surface 55 of the groove is, after all, recessed relative to the sliding surfaces of the plate 65 belonging to the opener part. Admittedly, plate 46 is not shown in FIG. 6, but it only reaches the dividing plane 93, 5 so there is still a recess. And milk spilled on top of plate 46 is not brought up to the opening 28, for the plate portion 65 of the opener portion slides on top of the surfaces 53,54,56, all of which are raised relative to the center portion.

Skulle der nu alligevel, og det er meget usandsynligt, spildes lidt mælk ovenpå en hvilken som 10 helst af glidefladerne 53, 54, så vil denne spildte mælk heller Ikke føres med op til åbningen 28 ved næste indføring af åbner-delen - på grund af indsnævringen ved fladen 56.If, however, and now it is very unlikely, a little milk is spilled on top of any of the sliding surfaces 53, 54, then this spilled milk will also not be brought up to the opening 28 at the next introduction of the opener part - due to the constriction at the surface 56.

Med tiden bliver uundgåeligt visse dele af komblhanen slidt, navnlig visse af pakningerne. Man ser, f.eks. af fig. 8, at det er uhyre let at udskifte pakningen 31 omkring åbningen 28: Man skal 15 blot skubbe pladen fremad manuelt, tage den gamte pakning ud og sætte den nye 1. Tilsvarende gælder for pakningerne 45 og 51: Den øvre pakning 51 er umiddelbart tilgængelig ved blot at løsne én skrue 48 og tage pladen 46 af. Den nedre pakning 45 kan også let nås ad samme vej -eller gennem åbningen 40.In time, certain parts of the comb faucet inevitably wear out, especially some of the gaskets. One sees, e.g. of FIG. 8, that it is extremely easy to replace the gasket 31 around the opening 28: 15 simply push the plate forward manually, remove the old gasket and insert the new 1. The same applies to gaskets 45 and 51: The upper gasket 51 is readily available by simply loosening one screw 48 and removing plate 46. The lower gasket 45 can also be easily reached by the same path or through the opening 40.

20 I forbindelse med vask af mælkesystemet vil åbningen 28 og undersiden af glkfespjældet 33 blive renset automatisk ved gennemskylninger af mælkeledningen 11. Ventøhus-delen er af meget enkel og rengøringsvenlig form, idet alle kritiske flader, der kan komme i kontakt med mælk, er umiddelbart tilgængelige for vandstråle, klud eller børste.20 In connection with washing the milk system, the opening 28 and the underside of the mucus damper 33 will be automatically cleaned by flushing the milk line 11. The Ventøhus part is of a very simple and easy to clean form, all critical surfaces that can come in contact with milk are immediately available for water jet, cloth or brush.

25 Som vist på fig. 2 kan kombihanen ifølge opfindelsen faktisk også anvendes til samtidig malkning af to køer. Den kan nemlig, hvad trykfald, ydelser og flow angår for vakuum og mælk, fuldt leve op til de normer, der er på området i dag.25 As shown in FIG. 2, the combination male according to the invention can in fact also be used for simultaneously milking two cows. In terms of pressure drop, performance and flow for vacuum and milk, it can fully live up to the standards in the field today.
