Abstract

A hand-held dish washing spray has a handle (10) around an inner passage (40) with a cylindrical insert (42) and a free-moving sliding piston (52). The cylinder is open at one end to a shut-off valve (64). Together, the cylinder (42) and piston (52) limit the volume of an air-filled void (56). If the valve is closed suddenly, the recoil is dampened by movement of the piston towards the cylinder base (44), compressing the air (56).

Description

Die vorliegende Erfindung betrifft eine Brause, insbesondere Geschirrwaschbrause, gemäss dem Oberbegriff des Patentanspruchs 1.The present invention relates to a shower, in particular dishwashing spray, according to the preamble of patent claim 1.

Eine Brause dieser Art ist beispielsweise aus der EP-A-0 656 503 bekannt. Sie weist einen rohrartigen Handgriff auf, der an seinem einlassseitigen Ende einen Anschlussnippel für einen Zuleitungsschlauch und an seinem auslassseitigen Ende einen Brausekopf und ein Absperrventil trägt. Das Absperrventil ist mittels eines Handhebels gegen die Kraft einer zum Schliessen bestimmten Rückstellfeder betätigbar. Innerhalb des Handgriffs erstreckt sich ein inneres Rohr vom Anschlussnippel zum Absperrventil. Dieses Rohr ist von einem gummielastischen Schlauch umgeben und weist voneinander beabstandet angeordnete Öffnungen in das Innere des Schlauches auf. Beim raschen Schliessen des Absperrventils entsteht ein vorübergehender Überdruck infolge der zu rasch abgebremsten Wassersäule des zugeführten Wassers. Zur Dämpfung dieses Druckstosses in der Zuleitung mit seinen nachteiligen Folgen dient das innere Rohr mit dem übergestülpten Schlauch, welcher sich vorübergehend als nachgiebige Wandung in einen Hohlraum im Handgriff ausdehnt.A shower of this type is known, for example, from EP-A-0 656 503. It has a tubular handle, which carries at its inlet-side end a connection nipple for a supply hose and at its outlet end a shower head and a shut-off valve. The shut-off valve can be actuated by means of a hand lever against the force of a return spring intended for closing. Inside the handle, an inner tube extends from the nipple to the shut-off valve. This tube is surrounded by a rubber-elastic tube and has spaced-apart openings in the interior of the tube. The rapid closing of the shut-off valve creates a temporary overpressure due to the rapidly decelerated water column of the water supplied. To dampen this pressure surge in the supply line with its adverse consequences, the inner tube is used with the tube slipped over, which temporarily expands as a resilient wall in a cavity in the handle.

Eine weitere Brause mit einem auf demselben Prinzip beruhenden Dämpfungssystem für Druckstösse ist aus der EP-A-0 704 252 und der entsprechenden US-A-5,732,884 bekannt.Another shower with a pressure surge absorbing system based on the same principle is known from EP-A-0 704 252 and corresponding US-A-5,732,884.

Beim Schliessen des Absperrventils wandert der dadurch erzeugte Druckstoss vom Absperrventil durch das innere Rohr in Richtung gegen den Anschlussnippel. Bei dieser Bewegung erreicht der Druckstoss nacheinander die Öffnungen, was zu einer stufenartigen Dämpfung des Druckstosses führt, bis dieser den Anschlussnippel erreicht hat.When closing the shut-off valve, the pressure surge generated thereby migrates from the shut-off valve through the inner tube in the direction of the connection nipple. During this movement, the pressure surge successively reaches the openings, which leads to a step-like damping of the pressure surge, until it has reached the connection nipple.

Zur Verhinderung oder Reduzierung von Druckstössen ist es aus der CH-A-647 165 auch bekannt, das Absperrventil einer Geschirrwaschbrause, auch bei raschem Loslassen des Handhebels, verzögert schliessen zu lassen. In einem Käfig ist ein im Schliesssinne des Absperrventils und mit diesem wirkverbundener, federbelasteter Ventilkolben geführt, durch welchen hindurch ein als Drossel wirkender Verbindungskanal verläuft. Der Verbindungskanal verbindet eine vom Käfig und dem Ventilkolben begrenzte Käfigkammer mit dem von einem im Innern des Handgriffs angeordneten Zylinderrohr begrenzten Strömungskanal für das Wasser. Infolge der Drosselwirkung des Verbindungskanals kann das Wasser nur mit einer begrenzten Menge pro Zeiteinheit in die Käfigkammer hineinströmen bzw. aus dieser verdrängt werden. Dadurch ist die Geschwindigkeit, mit welcher das Absperrventil geöffnet und geschlossen werden kann begrenzt.To prevent or reduce pressure surges, it is also known from CH-A-647 165, the shut-off valve of a dishwashing spray, even with rapid release of the hand lever to close delayed. In a cage in the closing sense of the shut-off valve and with this operatively connected, spring-loaded valve piston is guided, through which runs a throttle acting as a connecting channel. The connecting channel connects a cage chamber delimited by the cage and the valve piston with the flow channel for the water bounded by a cylinder tube arranged in the interior of the handle. As a result of the throttling effect of the connecting channel, the water can flow into the cage chamber only with a limited amount per unit time or be displaced from it. This limits the speed at which the shut-off valve can be opened and closed.

Es ist eine Aufgabe der vorliegenden Erfindung, eine gattungsgemässe Brause zu schaffen, die bei einfachem Aufbau ein optimales Dämpfungsverhalten für Druckstösse aufweist.It is an object of the present invention to provide a generic shower, which has a simple structure optimal damping behavior for pressure surges.

Diese Aufgabe wird mit einer Brause gelöst, die die Merkmale des Patentanspruchs 1 aufweist.This object is achieved with a shower, which has the features of claim 1.

Erfindungsgemäss ist im Innern eines Strömungskanals ein Zylinderelement angeordnet, in dem sich ein Gasvolumen zum Dämpfen der Druckstösse befindet. Da das Zylinderelement in seinem dem Absperrorgan zugewandten Endbereich offen ist, steht der entsprechende gesamte Strömungsquerschnitt zum Dämpfen der Druckstösse dauernd zur Verfügung. Weiter befindet sich dieser Strömungsquerschnitt in der Nähe beim Absperrventil, wo beim schnellen Schliessen die Druckstösse erzeugt werden. Weiter befindet sich das Zylinderelement im Innern des Strömungskanals, was zur Verhinderung der geradlinigen Ausbreitung der Druckstösse und somit auch zu deren Dämpfung beiträgt.According to the invention, a cylinder element is arranged in the interior of a flow channel in which there is a gas volume for damping the pressure surges. Since the cylinder element is open in its end region facing the obturator, the corresponding entire flow cross section is permanently available for damping the pressure surges. Next is this flow cross-section in the vicinity of the shut-off valve, where the pressure surges are generated during rapid closure. Next is the cylinder element in the interior of the flow channel, which contributes to the prevention of the rectilinear propagation of the pressure surges and thus also to their attenuation.

Die in den Figuren gezeigte, als Geschirrwaschbrause ausgebildete Brause weist einen Handgriff 10 mit einer rohrartigen Griffschale 12 auf. Konzentrisch zur Griffschale 12 und innerhalb dieser ist eine Verbindungshülse 14 angeordnet, die einerends mit einem Anschlussnippel 16 und andernends mit einem Brausekopfelement 18 verschraubt ist. In seinem freien Endbereich weist der Anschlussnippel 16 ein Gewinde auf, das ein Anschlussmittel 20 bildend zum Anschliessen eines Schlauches für die Zuleitung von Wasser bestimmt ist. Andererseits ist am freien Ende des Brausekopfelements 18 ein Brausesieb 22 eingesetzt, welches mittels eines ringartigen Siebhalters 24 gehalten ist und welcher umfangsseitig von einem gummielastischen Schutzring 26 umgriffen ist. Das Brausekopfelement 18 mit dem Brausesieb 22, dem Siebhalter 24 und Schutzring 26 bildet einen Brausekopf 28.The shower shown in the figures, designed as a dishwashing spray has a handle 10 with a tubular handle shell 12. Concentric with the grip 12 and within this a connecting sleeve 14 is arranged, which is screwed one end with a connection nipple 16 and the other with a shower head element 18. In its free end region, the connection nipple 16 has a thread, which is a connecting means 20 forming for connecting a hose for the supply of water intended. On the other hand, at the free end of the shower head element 18, a shower screen 22 is used, which is held by means of an annular screen holder 24 and which is peripherally encompassed by a rubber-elastic protection ring 26. The shower head element 18 with the shower screen 22, the screen holder 24 and guard ring 26 forms a shower head 28th

Der Anschlussnippel 16 weist eine in den Figuren nicht gezeigte, über einen Teil des Umfangs sich erstreckende Anschlagschulter auf, welche mit dem diesseitigen Ende der Griffschale 12 zusammenwirkt. Andererseits weist die Griffschale, wie dies den Fig. 2 und 3 zu entnehmen ist, auf ihrer Innenseite eine über einen Teil des Umfangs sich erstreckende Anschlagschulter 32 auf, welche mit einer Gegenschulter am Brausekopfelement 18 zusammenwirkt. Dadurch ist die Griffschale 12 in axialer Richtung festgehalten und gegenüber Verdrehung dadurch gesichert, dass sie eine nicht gezeigte Verdrehsicherungszunge aufweist, die mit einer Verdrehsicherungsfläche am Anschlussnippel 16 zusammenwirkt. In eine Umfangsnut am Brausekopfelement 18 ist ein O-Ring 36 eingesetzt, an welchem die Griffschale 12 mit ihrem Endbereich anliegt, um den zu Wärmeisolationszwecken ausgebildeten Hohlraum 38 zwischen der Griffschale 12 und der Verbindungshülse 14 abzudichten.The connection nipple 16 has a not shown in the figures, over a part of the circumference extending stop shoulder, which cooperates with the this side end of the handle shell 12. On the other hand, the handle shell, as can be seen in FIGS. 2 and 3, has on its inside a stop shoulder 32 which extends over part of the circumference and which cooperates with a counter shoulder on the shower head element 18. As a result, the grip shell 12 is held in the axial direction and secured against rotation by having an anti-rotation tongue, not shown, which cooperates with an anti-rotation surface on the connection nipple 16. In a circumferential groove on the shower head element 18, an O-ring 36 is used, on which the grip shell 12 abuts with its end portion to seal the heat insulating purposes formed cavity 38 between the handle shell 12 and the connecting sleeve 14.

Die Verbindungshülse 14 begrenzt einen Strömungskanal 40, durch welchen das Wasser vom Anschlussnippel 16 zum Brausekopf 18 geleitet wird. In diesem Strömungskanal 40 befindet sich konzentrisch zur Verbindungshülse 14 ein Zylinderelement 42, dessen Länge in axialer Richtung gemessen etwa halb so gross ist wie die gesamte Länge der Geschirrwaschbrause. Das Zylinderelement 42 ist anschlussmittelseitig mittels eines Zylinderbodens 44 verschlossen, von welchem, einstückig mit dem Zylinderelement 42 ausgebildet, ein hohlzylinderförmiger Halteflansch 46 absteht, welcher in eine entsprechende Ausnehmung im Anschlussnippel I6 eingreift. Zur konzentrischen Halterung des Zylinderelements 42 dienen weiter von der Verbindungshülse 14 nach innen abstehende Rippen, die in axialer Richtung über etwa die halbe Länge des Zylinderelements 42 verlaufen. Das Innere des Halteflansches 46 kommuniziert einerseits mit der Einlassöffnung 48 des Anschlussnippels 16 und andererseits über radiale Durchlässe 50 mit dem ringförmigen Strömungskanal 40 zwischen der Verbindungshülse 14 und dem Zylinderelement 42.The connection sleeve 14 delimits a flow channel 40, through which the water is conducted from the connection nipple 16 to the shower head 18. In this flow channel 40 is concentric with the connecting sleeve 14, a cylinder member 42, whose length measured in the axial direction approximately half the size of the entire length of the dishwashing spray. The cylinder element 42 is closed on the connection means side by means of a cylinder bottom 44, from which, formed integrally with the cylinder element 42, a hollow-cylindrical retaining flange 46 protrudes, which engages in a corresponding recess in the connection nipple I6. For concentric support of the cylinder member 42 further extending from the connecting sleeve 14 inwardly projecting ribs extending in the axial direction over approximately half the length of the cylinder member 42. The interior of the holding flange 46 communicates on the one hand with the inlet opening 48 of the connecting nipple 16 and on the other hand via radial passages 50 with the annular flow channel 40 between the connecting sleeve 14 and the cylinder element 42nd

Im Zylinderelement 42 ist ein doppelt wirkender Kolben 52 in axialer Richtung frei beweglich gelagert. Dieser mittels zweier in axialer Richtung voneinander beabstandeten Dichtmanschetten 54 dichtend am Zylinderelement 42 geführte Kolben 52 begrenzt zusammen mit dem Zylinderelement 42 ein Gasvolumen 56, das zum Dämpfen von Druckstössen bestimmt ist, wie dies weiter unten zu beschreiben ist.In the cylinder member 42, a double-acting piston 52 is mounted freely movable in the axial direction. This by means of two axially spaced sealing sleeves 54 sealingly guided on the cylinder member 42 piston 52 together with the cylinder member 42 defines a gas volume 56 which is intended to dampen pressure surges, as will be described below.

Auf dem freien Ende des Zylinderelements 42 sitzt ein Zylinderdeckel 58 - beispielsweise mittels eines Bajonettverschlusses am Zylinderelement 42 befestigt -, welcher einen zentralen Durchlass 60 aufweist. Durch diesen zentralen Durchlass 60 hindurch ist der Kolben 52 diesseitig mit dem Druck des Wassers beaufschlagt. Andererseits wirkt auf den Kolben 52 der Druck im Gasvolumen 56.On the free end of the cylinder member 42 sits a cylinder cover 58 - attached, for example by means of a bayonet lock on the cylinder element 42 - which has a central passage 60. Through this central passage 60 through the piston 52 is acted upon on this side with the pressure of the water. On the other hand, the pressure in the gas volume 56 acts on the piston 52.

Am Zylinderdeckel 58 stützt sich eine als Rückstellfeder 62 für ein Absperrventil 64 wirkende Druckfeder ab, die andererseits auf der Aussenseite eines Schieberbodens 66 eines becherförmig ausgebildeten Schiebers 68 anliegt. Der Schieber 68 ist mit seinem Mantel 70 am, im wesentlichen hohlzylinderförmigen Brausekopfelement 18 in axialer Richtung verschiebbar geführt. In eine radial auf der Innenseite angeordneten Umfangsnut des Brausekopfelements 18 ist ein erster Quad-Ring 72 eingesetzt, welcher mit dem Mantel 70 zusammenwirkt, um den Austritt von Wasser aus dem Strömungskanal 40 zwischen dem Brausekopfelement 18 und dem Schieber 68 hindurch zu verhindern.On the cylinder cover 58, a spring acting as a return spring 62 for a check valve 64 is supported, on the other hand on the outside of a slide bottom 66 of a cup-shaped slide 68 rests. The slider 68 is guided with its jacket 70 on, substantially hollow cylindrical shower head element 18 in the axial direction displaceable. In a radially arranged on the inside circumferential groove of the shower head element 18, a first quad-ring 72 is used, which cooperates with the jacket 70 to prevent the escape of water from the flow channel 40 between the shower head element 18 and the slider 68 therethrough.

Auf der Innenseite des Schiebers 68 liegt am Schieberboden 66 ein im Querschnitt C-förmiger, rotationssymmetrischer Dichtungshalter 74 an, in welchem ein ringscheibenförmiges Dichtelement 76 aufgenommen ist. Dieses ist mittels einer Schraube 78 gehalten, welche den Dichtungshalter 74 und Schieberboden 66 durchgreift und auf welche eine Hutmutter 80 aufgeschraubt ist. Diese greift in axialer Richtung in die Rückstellfeder 62 ein, um ein radiales Verschieben zu vermeiden. Überdies ist die Rückstellfeder 62 auch am Zylinderdeckel 58 gegen radiales Verschieben gehalten, indem der Zylinderdeckel 58 eine Vertiefung für die Rückstellfeder 62 aufweist.On the inside of the slider 68 is located on the slide bottom 66 a in cross-section C-shaped, rotationally symmetrical seal holder 74, in which an annular disc-shaped sealing element 76 is added. This is held by a screw 78, which passes through the seal holder 74 and slide bottom 66 and on which a cap nut 80 is screwed. This engages in the axial direction in the return spring 62 in order to avoid a radial displacement. Moreover, the return spring 62 is also held on the cylinder cover 58 against radial displacement by the cylinder cover 58 has a recess for the return spring 62.

Das am Schieber 68 befestigte Dichtelement 76 bildet ein Verschlusselement des Absperrventils 64, welches mit einem am freien Ende eines Ventilsitzelements 82 ausgebildeten ringförmigen Ventilsitz 84 zusammenwirkt. Das am Brausekopfelement 18 mittels einer Schraubverbindung befestigte, wenigstens annähernd hohlzylinderförmige Ventilsitzelement 82 greift von der dem Schieberboden 66 abgewandten Seite her in den Schieber 68 ein und weist umfangsseitig eine Nut auf, in welcher ein zweiter Quad-Ring 72' angeordnet ist. Dieser liegt an der Innenwand des Mantels 70 des Schiebers 68 an und verhindert den Austritt von Wasser aus dem vom Schieber 68, dem Ventilsitzelement 82 und dem Dichtelement 76 begrenzten Raum. Dieser Raum ist über radiale Durchströmöffnungen 86 durch den Mantel 70 des Schiebers 68 hindurch mit dem Strömungskanal 40 verbunden.The attached to the slider 68 sealing element 76 forms a closure element of the shut-off valve 64, which cooperates with a formed at the free end of a valve seat member 82 annular valve seat 84. The attached to the shower head element 18 by means of a screw, at least approximately hollow cylindrical valve seat member 82 engages from the slider bottom 66 remote from the side into the slider 68 and has circumferentially on a groove in which a second quad-ring 72 'is arranged. This is applied to the inner wall of the jacket 70 of the slider 68 and prevents the escape of water from the slide 68, the valve seat member 82 and the sealing element 76 limited space. This space is connected via radial throughflow openings 86 through the jacket 70 of the slide 68 through to the flow channel 40.

Wie Fig. 1 zeigt, ist das ansonsten rotationssymmetrisch und hohlzylinderartig ausgebildete Brausekopfelement 18 mit zwei einander diametral gegenüberliegenden Durchgriffsöffnungen 88 versehen, welche je von einem Gabelelement 90 eines Handhebels 92 durchgriffen sind. Die zueinander parallel verlaufenden Gabelelemente 90 sind in ihrem freien Endbereich mittels eines Lagerstifts 94 am Brausekopfelement 18 schwenkbar gelagert. Überdies durchgreifen die Gabelelemente 90 - wie dies der Fig. 1 entnehmbar ist - aussenliegende Mitnehmerausnehmungen 96 am Mantel 70 des Schiebers 68. Dadurch ist eine Wirkverbindung über den Schieber 68 zwischen dem Handhebel 92 und dem als Verschlusselement dienenden Dichtelement 76 des Absperrventils 64 hergestellt.As shown in FIG. 1, the otherwise rotationally symmetrical and hollow cylinder-like design shower head element 18 is provided with two diametrically opposed through openings 88, which are each penetrated by a fork element 90 of a hand lever 92. The mutually parallel fork elements 90 are pivotally mounted in its free end region by means of a bearing pin 94 on the shower head element 18. In addition, the fork elements 90 - as can be seen in FIG. 1 - reach through outer driver recesses 96 on the casing 70 of the slide 68. This produces an operative connection via the slide 68 between the hand lever 92 and the sealing element 76 of the shut-off valve 64 serving as the closure element.

Der mit den Gabelelementen 90 einstückig verbundene, und bezüglich diesen abgewinkelte Hebelschaft 98 liegt bei geöffnetem Absperrventil 64, wie dies der Fig. 3 entnehmbar ist, wenigstens annähernd an der Aussenseite der Griffschale 12 an und kann mittels eines Halterings 100 in dieser Stellung entgegen der Wirkung der Rückstellfeder 62 gehalten werden. Der Haltering 100 ist am Anschlussnippel 16 begrenzt drehbar gelagert und weist eine radiale Ausnehmung 102 mit einer Hinterschneidung 104 auf. In der entsprechenden Drehlage des Halterings 100 kann der freie Endbereich des Hebelschafts 98 in die radiale Ausnehmung 102 eingeführt werden und durch anschliessendes Drehen des Halterings 100 ist der Handhebel 92 gegen Verschwenken in der Hinterschneidung 104 gehalten, wie dies der Fig. 3 entnehmbar ist.The integrally connected to the fork elements 90, and with respect to this bent lever shaft 98 is open with stop valve 64, as shown in FIG. 3, at least approximately on the outside of the handle shell 12 and can by means of a retaining ring 100 in this position against the effect the return spring 62 are held. The retaining ring 100 is mounted rotatably limited to the connection nipple 16 and has a radial recess 102 with an undercut 104. In the corresponding rotational position of the retaining ring 100, the free end portion of the lever shaft 98 can be inserted into the radial recess 102 and by subsequently rotating the retaining ring 100 of the hand lever 92 is held against pivoting in the undercut 104, as shown in FIG. 3 can be removed.

In der Fig. 1 ist gestrichelt ein Ballon oder Balg 106 angedeutet, der sich im Gasvolumen 56 befindet. Ist ein Ballon bzw. Balg 106 vorhanden, ist dieser mit einem Gas, vorzugsweise Luft, gefüllt und stellt eine zuverlässige Funktion der Druckstossdämpfung selbst dann sicher, wenn die Dichtung zwischen Kolben 52 und Zylinderelement 42 beschädigt oder nicht mehr funktionstüchtig sein sollte.In FIG. 1, a balloon or bellows 106 is indicated by dashed lines, which is located in the gas volume 56. If a balloon 106 is present, it is filled with a gas, preferably air, and ensures a reliable function of the pressure shock absorption even if the seal between piston 52 and cylinder element 42 should be damaged or no longer functional.

Es ist auch denkbar, auf den Kolben 52 ganz zu verzichten und in diesem Fall einen Ballon bzw. Balg 106 im vom Zylinderelement 42 begrenzten Raum anzuordnen.It is also conceivable to completely dispense with the piston 52 and, in this case, to arrange a balloon or bellows 106 in the space delimited by the cylinder element 42.

Die Funktionsweise der in den Figuren gezeigten Geschirrwaschbrause ist wie folgt. Bei geschlossenem Absperrventil 64 - wie dies in den Fig. 1 und 2 gezeigt ist - steht das Wasser im Strömungskanal 40 unter einem Druck, der dem statischen Druck der Wasserspeisung entspricht. Der Kolben 52 befindet sich dabei, wie in der Fig. 2 gestrichelt angedeutet, in einer Position, in welcher das Gas im Gasvolumen 56 auf einen Druck komprimiert ist, welcher dem Wasserdruck entspricht.The operation of the dishwashing spray shown in the figures is as follows. With closed shut-off valve 64 - as shown in FIGS. 1 and 2 - the water in the flow channel 40 is under a pressure corresponding to the static pressure of the water supply. The piston 52 is thereby, as indicated by dashed lines in Fig. 2, in a position in which the gas is compressed in the gas volume 56 to a pressure corresponding to the water pressure.

Wird nun der Handhebel zum Öffnen des Absperrventils 64 in Richtung auf die Griffschale 12 zu verschwenkt, wird durch diese Schwenkbewegung der Schieber 68 in Richtung gegen den Anschlussnippel 16 und gegen die Kraft der Rückstellfeder 62 translatorisch bewegt, was zu einem Abheben des Dichtelements 76 vom Ventilsitz 84 führt, Fig. 3. Dadurch strömt Wasser von der Einlassöffnung 48 des Anschlussnippels 16 in den Halteflansch 46, von dort durch die zwei Durchlässe 50 in den ringförmigen Strömungskanal 40 und entlang der Aussenseite des Zylinderelements 42 bis zum Brausekopfelement 18. Dort durch die Durchströmöffnungen 86 im Schieber 68 hindurch zum Absperrventil 64 und von diesem durch das Ventilsitzelement 82 zum vom Brausesieb 22 gebildeten Auslass der Geschirrwaschbrause. Infolge des Wasserflusses sinkt der Druck im Strömungskanal 40, was dazu führt, dass sich der Kolben 52 unter dem Druck des Gases - vorzugsweise Luft - im Gasvolumen 56 in Richtung gegen seine in den Fig. 1 bis 3 mit ausgezogenen Linien gezeigte Endlage bewegt. Beientsprechend gewähltem Druck im Gasvolumen 56 kann der Kolben 52 am Zylinderdeckel 58 zur Anlage gelangen.If now the hand lever for opening the shut-off valve 64 to be pivoted in the direction of the handle shell 12, the slider 68 is translationally moved in the direction against the connecting nipple 16 and against the force of the return spring 62, resulting in a lifting of the sealing element 76 from the valve seat As a result, water flows from the inlet opening 48 of the connecting nipple 16 into the retaining flange 46, from there through the two passages 50 into the annular flow channel 40 and along the outside of the cylinder element 42 to the shower head element 18. There through the flow openings 86 in the slide 68 through to the check valve 64 and from there through the valve seat member 82 to the shower 22 formed by the outlet the dishwashing spray. As a result of the water flow, the pressure in the flow channel 40 decreases, which causes the piston 52 under the pressure of the gas - preferably air - moves in the gas volume 56 in the direction of its end position shown in FIGS. 1 to 3 in solid lines. Appropriately selected pressure in the gas volume 56, the piston 52 on the cylinder cover 58 come to rest.

Wird zum Unterbrechen des Wasserflusses der Handhebel 92 losgelassen, schliesst das Absperrventil 64 unter der Kraft der Rückstellfeder 62 sehr schnell. Dadurch wird der Wasserfluss schlagartig unterbrochen, was infolge des Abbremsens der Wassersäule zur Erzeugung eines Druckstosses führt. Dieser Druckstoss wird nun gedämpft, indem sich der Kolben 52 in Richtung gegen den Zylinderboden 44 hin bewegt. Wird der zentrale Durchlass 60 so gross wie möglich ausgebildet und befindet sich dieser nahe beim Absperrventil 64, wird eine optimale Dämpfungswirkung erzielt. Diese wird weiter dadurch unterstützt, dass der vom Kolben 52 und Zylinderelement 42 begrenzte Hubraum möglichst lange ausgebildet ist. Weiter üben die ringförmige Ausbildung des Strömungskanals 40 und die Durchlässe 50 sowie Durchströmöffnungen 86 eine dämpfende Wirkung auf den Druckstoss aus, so dass die Zuleitung selbst bei schnellem Schliessen des Absperrventils einer unwesentlich höheren Druckbelastung als jener des statischen Speisewasserdrucks ausgesetzt ist. Je nach Höhe und Dauer des Druckstosses kann sich der Kolben 52 über die in der Fig. 2 gestrichelt angedeutete Lage hinaus auf den Zylinderboden 44 zu bewegen. Sobald dann wieder Staudruck anliegt, bewegt er sich in die gestrichelt gezeigte Lage zurück.If the hand lever 92 is released to interrupt the flow of water, the shut-off valve 64 closes very quickly under the force of the return spring 62. As a result, the flow of water is suddenly interrupted, resulting in the generation of a pressure surge as a result of the deceleration of the water column. This pressure surge is now damped by the piston 52 moving in the direction towards the cylinder bottom 44. If the central passage 60 is made as large as possible and is close to the shut-off valve 64, an optimal damping effect is achieved. This is further supported by the fact that the piston 52 and cylinder member 42 limited displacement is formed as long as possible. Further practice the annular formation of the flow channel 40 and the passages 50 and flow openings 86 a damping effect on the pressure surge, so that the lead is exposed even at fast closing of the shut-off valve a slightly higher pressure load than that of the static feedwater pressure. Depending on the height and duration of the pressure surge, the piston 52 can move beyond the position indicated by dashed lines in FIG. 2 onto the cylinder bottom 44. As soon as back pressure rests, he moves back to the position shown in dashed lines.

Um die Dämpfungswirkung weiter zu optimieren ist der Kolben 52 möglichst leicht ausgebildet, was beispielsweise durch Herstellung aus Kunststoff ermöglicht wird. Die in den Figuren gezeigten sacklochartigen axialen Ausnehmungen an Kolben 52 tragen ebenfalls zur Gewichtsreduktion bei. Überdies gewährleisten die im Querschnitt V-förmig ausgebildeten Dichtmanschetten 54 ein leicht gängiges Bewegen des Kolbens 52 bei zuverlässiger Dichtung.In order to further optimize the damping effect of the piston 52 is formed as easily as possible, which is made possible for example by making plastic. The in the figures shown blind hole-like axial recesses on the piston 52 also contribute to the weight reduction. Moreover, the cross-sectionally V-shaped sealing sleeves 54 ensure smooth movement of the piston 52 with reliable sealing.

In der in den Fig. 1 bis 3 gezeigten Ausbildungsform ist das Zylinderelement 42 stirnseitig infolge des zentralen Durchlasses 60 im Zylinderdeckel 58 offen. Es ist jedoch auch denkbar, im freien Endbereich radiale Durchlässe vorzusehen, wobei jedoch der Kolben 52 derart auszubilden bzw. derart abzustützen ist, dass diese Durchlässe wasserseitig des Kolbens 52 angeordnet sind.In the embodiment shown in FIGS. 1 to 3, the cylinder element 42 is open on the face side due to the central passage 60 in the cylinder cover 58. However, it is also conceivable to provide radial passages in the free end region, but the piston 52 is to be embodied or supported in such a way that these passages are arranged on the water side of the piston 52.

Bei der in den Figuren dargestellten und weiter oben beschriebenen Ausführungsform der erfindungsgemässen Brause ist der Brausekopf bezüglich des Handgriffs fest angeordnet. Es ist jedoch auch denkbar, den Brausekopf zusammen mit dem Verschlusselement des Absperrventils in axialer Richtung bewegbar anzuordnen, wie dies beispielsweise aus der CH-A-647 165 bekannt ist.In the embodiment of the inventive shower shown in the figures and described above, the shower head is fixed relative to the handle. However, it is also conceivable to arrange the shower head movable together with the closure element of the shut-off valve in the axial direction, as is known for example from CH-A-647 165.

Es ist auch denkbar, das Absperrventil unterschiedlich auszubilden. Diesbezüglich wird auch auf die EP-A-0 656 503 und EP-A-0 704 252 verwiesen.It is also conceivable to design the shut-off valve differently. In this regard, reference is also made to EP-A-0 656 503 and EP-A-0 704 252.

Weiter kann auf eine Verbindungshülse 14 verzichtet werden. In diesem Fall werden der Anschlussnippel 16 und der Brausekopf 28 an der Griffschale befestigt. Das Vorsehen einer Verbindungshülse 14 hat jedoch den Vorteil einer guten Wärmeisolierung zwischen dem gegebenenfalls heissen Wasser im Strömungskanal 40 und der äusseren Oberfläche der Griffschale 12.Next can be dispensed with a connection sleeve 14. In this case, the nipple 16 and the showerhead 28 are attached to the handle. However, the provision of a connecting sleeve 14 has the advantage of good thermal insulation between the optionally hot water in the flow channel 40 and the outer surface of the handle shell 12th
