Description

RADIATOR THAT CAN BE DISAPPEARED IN A CLEANING POSITION

The invention relates to a jet regulator with a sleeve-shaped Strahlreglergehause which is mounted on the water outlet of a sanitary outlet fitting, and with a wall which carries a AuslaufStirnseite the jet regulator forming hole structure and the Strahlreglergehäuse between a use position in which the hole structure is transverse to a downstream Housing opening of the jet regulator housing extends, and a cleaning position is pivotable in which the water flowing through the jet regulator housing water can flow out of the jet regulator housing through at least one opening gap formed between the wall and the adjacent Gehäuseinnenumfangswandung. From WO 2014/142766 Al a jet regulator of the type mentioned above is already known. The previously known jet regulator has a sleeve-shaped jet regulator housing, which can be mounted on the water outlet of a sanitary outlet fitting in order to form the outflowing water there into a homogeneous and non-spraying water jet. In Strahlreglergehause a ring wall is provided, which carries a the outlet end face of the prior art jet regulator forming hole structure. This annular wall has on opposite sides of its outer circumference in each case a stub axle, which stub axle are mounted on the inner circumference of the jet regulator housing. The annular wall is mounted pivotably in the jet regulator housing about this stub axle such that the annular wall in the jet regulator housing is in a position of use in which the perforated structure extends transversely across a downstream sleeve opening the jet regulator housing extends, and a cleaning position is pivotable in which the water flowing through the jet regulator housing can flow out of the jet regulator housing on both sides of the annular wall by opening gaps formed between the annular wall and the adjacent inner wall of the inner housing. In this way, in the water entrained limescale or other

Dirt particles, which have accumulated upstream of the hole structure, are flushed out and carried out of the jet regulator housing through one of the opening gaps, in order to continue to ensure the trouble-free functioning of the jet regulator. On the side of the ring, there is a pin as a handle, which is intended to facilitate the pivoting of the ring wall from the position of use into the cleaning position and vice versa. The disadvantage, however, is that this handle remains clearly visible in most relative positions of the jet regulator in the water outlet and can encourage many people to pivot the ring wall without necessity and optionally also leave in their cleaning position. In addition, a handle projecting at the water outlet affects the appearance of the entire sanitary outlet fitting.

From DE 10 2005 010 550 B4 is already known a jet government with a jet regulator housing, which carries an external thread on its outer circumference, with which external thread of the previously known jet regulator can be screwed into an internal thread in the water outlet of a sanitary outlet fitting. The previously known jet regulator has a spherical-layer-shaped joint sleeve, which is provided on the inside circumference in a complementarily shaped joint socket on the downstream end region of the jet regulator housing. In this case, in the sleeve interior of the pivotable gela- gerten joint sleeve provided a perforated plate. Since the joint plate having the perforated plate is pivotably mounted, the outlet direction of the exiting water jet can be changed and reoriented if necessary. Since the joint sleeve abuts even at comparatively small pivoting angles on inflow side upstream components of the prior art jet regulator, which also serve as a pivot stop, a cleaning of the prior art jet regulator in the assembled state is neither possible nor provided.

There is therefore a particular object to provide a jet regulator of the type mentioned, which can be easily cleaned even in the assembled state, this jet regulator should not significantly affect the appearance of a sanitary outlet fitting despite ease of use.

The solution of this object is in the jet regulator of the type mentioned in particular that the wall has a spherical outer surface and is pivotally mounted with this spherical outer periphery in a socket, which is provided on the housing inhenumfangswandung the jet regulator housing. The jet regulator according to the invention has a sleeve-shaped jet regulator housing, which can be mounted on the water outlet of a sanitary outlet fitting. The jet regulator according to the invention has a wall designed, for example, as a joint or swivel sleeve and preferably designed as a ring wall, which has a spherical-layer-shaped outer circumference. This wall, which carries a hole structure forming the outlet end face of the jet regulator, is pivotably mounted with its spherical-layer-shaped outer circumference in a joint socket, which is provided on the Gehäuseinnenumfangswandung the jet regulator housing. The wall is pivotably mounted with its spherical outer periphery in the socket such that this wall in the jet regulator housing between a use position in which the hole structure extends transversely across a downstream housing opening of the jet regulator housing and a cleaning position is pivotable, in which the water flowing through the jet regulator housing can flow out of the jet regulator housing through at least one opening gap formed between the wall and the adjacent housing inner circumferential wall. Since no stub axles are provided on the wall of the jet regulator according to the invention, which fix the pivot axis of this wall in the jet regulator housing, the wall in the joint socket can also be rotated in the circumferential direction to any disturbing details, such as a protruding handle from the field of view of the beholder rotate. Since the wall can be pivoted in any rotational position arbitrarily between the position of use and the at least one cleaning position, the ease of handling of the jet regulator according to the invention is additionally favored.

A slight and pressure-free pivoting of the wall in the socket is further favored when the socket has at least in a partial area a complementary to the spherical layer wall shape.

It is particularly advantageous if the wall is rotatably mounted in the circumferential direction and pivotable in each rotational position in the joint socket.

So that the user recognizes the cleaning function and possibility as easily as possible, it is expedient if, at the wall tion a handle is provided, which preferably projects beyond the circumference or Abströmstirnseite the jet regulator housing. The user can therefore attack the handle in order subsequently to swivel the wall in the jet regulator housing. In this case, the user can control the pivoting operation at a distance above the sanitary outlet fitting without having to go with his face to the height of the water outlet. A particularly simple embodiment according to the invention provides that the handle is designed peg-shaped.

Thus, the wall is not pivoted by itself under the pressure of the inflowing water, it is advantageous if the wall in the use position on the jet regulator housing is preferably secured by means of a latching connection.

By way of example, such a latching connection can have at least one latching projection projecting on the handle, which can be latched to a circumferential latching groove on the housing outer circumference of the jet regulator housing or to at least one latching recess provided on the outflow side housing edge of the jet regulator housing. In particular, a circumferential groove on the outer peripheral locking groove which can be latched with a locking projection on the handle, allows the wall practically in each rotational position to lock such that a projecting beyond the water outlet handle from the field of view of the user passes. But it is also possible that the handle on the downstream housing front side of the jet regulator housing can be latched. For this purpose, at least one locking receptacle on the downstream housing front side. be provided, in which the handle locks can be.

It is a particular advantage of the inventive solution that the jet regulator according to the invention can also be designed as a ventilated jet regulator, in whose jet regulator housing the water flowing through is mixed with ambient air. If the jet regulator according to the invention is designed as a ventilated jet regulator, a homogeneous, non-spattering and pearly-soft water jet can be formed in the jet regulator according to the invention.

In this case, a preferred embodiment according to the invention that the jet regulator has a jet splitter, which decomposes the water flowing through into a plurality of individual jets. In order to remove the accumulating on the upstream side of this jet separator dirt particles, it is advantageous if the jet separator is held in the wall.

So that such dirt particles can not settle in the burster openings of the jet breaker, it is advantageous if the jet breaker is connected on the inflow side with a header or filter sieve. In this case, a preferred embodiment according to the invention provides that the jet splitter carries the inflow-side attachment or filter screen and that the attachment or filter screen is preferably hat-shaped or dish-shaped. In particular, a hat-shaped or plate-shaped attachment or filter screen can be designed so that this attachment or filter screen still remains in the enveloping circle formed or circumscribed by the pivotable wall.

The jet splitter may be formed, for example, as a perforated plate having a plurality of Zerlegeröffnungen. However, in order to adequately decelerate the inflowing water over a small distance and to be able to disassemble it, it is advantageous if the jet splitter is designed as a pot-shaped diffuser which has burster openings at the pot periphery of its pot shape and whose pot bottom forms a baffle surface, which the incoming water to redirects the Zerlegeröffnungen.

So that the water flowing through the jet splitter in the form of individual streams can then suck in the required ambient air, it is advantageous if the burster openings open into an annular gap which tapers in the direction of flow. Since the annular gap tapers in the direction of flow, the individual jets coming from the breaker openings and flowing into the annular gap are accelerated in such a way that, according to the Bernoulli equation, a negative pressure is created on the downstream side of the annular gap. By this, formed on the downstream side of the annular gap negative pressure ambient air can be sucked into the housing interior of the jet regulator housing, which is mixed there with the water flowing through.

In this case, an embodiment of the invention which is particularly easy to produce provides for the annular gap between the diffuser and a diffuser ring encompassing the diffuser.

A preferred development according to the invention provides that the wall has in its downstream part at least one open end and optionally also as an annular gap ventilation duct and that the annular gap surrounding inner wall portion forms an inner wall, the at least one vent and / or to which the hole structure is preferably integrally formed. The wall has in its downstream part of at least one front side open ventilation duct. By oriented to the outflow side duct opening ambient air can be sucked into the ventilation _channel: are subsequently passes through the at least one vent opening in the housing interior of the jet regulator according to the invention. It is expedient if the hole structure is preferably integrally formed on the inner wall bounding the ventilation channel in order to limit the mobility and the number of components of the jet regulator according to the invention.

So that the inventive _: aerator can withstand high water pressures, it is advantageous if the wall can be inserted from the inlet side of the jet regulator housing into this.

In order for the water flowing through the jet regulator according to the invention to flow through the hole structure in the wall and thus prevent undesired leakage flows past this hole structure, it is advantageous if a seal which is preferably designed as a ring seal is provided in the inflow-side subregion of the joint socket Wall and the housing inner circumference of the jet regulator housing seals.

On the one hand to fix the seal in the jet regulator housing and on the other hand to impede an undesired pushing out of the wall of the jet regulator housing, it is advantageous if a retaining ring is provided, which is latched on the one hand on the housing inner circumference of the jet regulator housing and on the other hand, the seal on the housing inner circumference Radiator housing secures.

In contrast, another preferred embodiment according to the invention provides that at least partially an elastic coating or layer is provided between the wall and serving as a joint cup portion of the jet regulator housing, which seals between these relatively pivotable components of the jet regulator. In this case, this elastically sealing layer or coating may be provided on the portion of the jet regulator housing serving as a joint socket. However, preference is given to an embodiment in which the wall on its outer circumference at least partially carries the circumferential elastic layer or coating.

In order to simplify the production of the jet regulator according to the invention, it is advantageous if the housing part of the jet regulator housing carrying the layer or coating or the wall carrying this layer or coating is produced as a multi-component plastic injection molded part.

An embodiment according to the invention provides that the jet regulator housing at its outer circumference has a ring paragraph or an annular flange and that the jet regulator can be mounted in a water outlet of a sanitary outlet fitting mountable sleeve-shaped outlet nozzle until the annular shoulder or annular flange abuts a support in the outlet nozzle or rests.

According to another proposal according to the invention it is provided that the jet regulator housing carries on its outer circumference of the housing an external thread, with which external thread the The aerator housing can be screwed or screwed onto an internal thread in the water outlet of the sanitary outlet fitting.

In order to be able to clean the jet regulator according to the invention at regular intervals in a simple manner, it is advantageous if in the cleaning position the water flowing through the jet regulator housing can flow out of the jet regulator, optionally through an opening gap formed on one side of the wall or on both sides of the wall.

It is a particular advantage of the jet regulator according to the invention that the wall which is in the form of a spherical layer on its outer circumference is pivotably mounted in a joint socket, without the need for providing stub axles on the outside of this wall. In order to bring the wall in its position of use in an oriented almost at right angles to the jet regulator longitudinal axis position, it is advantageous if at least one Ausrichtvorsprung projecting on the downstream side of the wall, in the position of use of the wall on the

Abströmstirnseite the jet regulator housing is applied. By means of this at least one alignment projection, an undesired tilted position of the wall in the position of use is avoided, which could otherwise lead to a likewise undesired inclined outflow of the outflowing water.

In this case, the handling of the jet regulator according to the invention and the alignment of its wall in the position of use is substantially facilitated if projecting at least two Ausrichtvorsprünge on the wall, which are arranged on both sides of the handle and at preferably equal distances from the handle on the Abströmstirnseite the wall. In order to be able to advantageously restrict the water consumption with the aid of the jet regulator according to the invention, it is advantageous if the jet regulator is preferably releasably connected to a flow regulator on its inflow-side end, which flow regulator regulates the water volume flowing through the jet regulator to a defined maximum value per unit time independently of pressure , With the help of this flow regulator it is avoided that the volume of water flowing through the jet regulator according to the invention in the position of use of the wall exceeds a predetermined maximum value, when the water pressure of the inflowing water increases more and more.

In one embodiment of the jet regulator according to the invention with upstream or upstream filter screen or filter, it is advantageous if the attachment screen on the flow regulator and the flow regulator on the jet regulator is particularly releasably held. In this preferred embodiment, the unit formed by the jet regulator, the flow rate regulator and the inflow-side attachment screen can be pivoted by means of the wall pivotably mounted in the jet regulator housing.

In some countries it is stipulated that the volume of water flowing out of the water outlet of a sanitary outlet fitting per unit of time must not exceed a statutory limit. In one embodiment, in which the jet regulator according to the invention carries the flow rate regulator, this flow rate regulator can not fulfill its function in the open position of the wall. But in order to meet the legal requirements in the open position of the wall of the jet regulator according to the invention, provides an embodiment according to the invention, that in the Inflow to the jet controller in the flow direction preferably at a distance from this an optionally also additional flow rate regulator is provided, which regulates the flow-through volume of water pressure independent to a maximum value possibly also legally per unit time.

Further developments according to the invention will become apparent from the description in conjunction with the claims and the drawings. The invention will be described in more detail below with reference to preferred exemplary embodiments.

FIGS. 1 to 41 show seven exemplary embodiments 101, 102, 103, 104, 105, 106 and 107 of a jet regulator. As shown by way of example in FIG. 7, the jet regulator designs 101, 102, 103, 104, 105, 106 and 107 can be mounted on the water outlet 1 of a sanitary outlet fitting 2 in order to form a homogeneous and non-spraying water jet there. The jet regulators 101, 102, 103, 104, 105, 106 and 107 shown here each have a wall 3 which carries a hole structure 4 forming the outlet end face of the jet regulators 101, 102, 103, 104, 105, 106 and 107. This wall 3, which is designed here as a joint or pivot sleeve and designed as an annular wall, is pivotally mounted with its spherical-layer-shaped outer periphery 5 in a joint socket 6, which is provided on the Gehäuseinnenumfangswandung a Strahlregler- housing 7. The wall 3 is pivotably mounted with its spherical-layer-shaped outer periphery 5 in the joint socket 6 such that this wall 3 is pivotable in the jet regulator housing 7 between a use position in which the hole structure 4 extends transversely across a downstream housing opening of the jet regulator housing 7, and a cleaning position, in which the water flowing through the jet regulator housing 7 through at least one between the wall 3 and the adjacent Gehäuseinnenurafangswandung formed opening gap 8 or 8, 9 can flow out of the jet regulator housing 7. Since on the wall 3- the jet regulator 101, 102, 103, 104, 105, 106, 107 no stub axle are provided which define the pivot axis of this wall 3 in the jet regulator housing 7, the wall 3 in the joint socket 6 can also rotate in the circumferential direction to turn any disturbing details, such as a laterally projecting handle, out of the field of view of the observer.

The molded into the housing inner circumference of the jet regulator housing 7 socket 6 has at least in a partial region to the spherical layer-shaped outer periphery 5 of the wall 3 complementary shape. The wall 3 is rotatable in the circumferential direction with its spherical-layer-shaped outer circumference 5 in the complementarily shaped joint socket 6 and is pivotably mounted in the joint socket 6 in each rotational position.

In order to facilitate the handling of the jet regulators 101, 102, 103, 104, 105, 106, 107 and to signal the pivotability of the wall 3, a handle 10 is provided on the wall 3, the side over the circumference of the jet regulator housing 7 or protrudes beyond its outlet end face 11. This handle 10 may be configured pin-shaped.

The jet regulator embodiments 101, 102, 103, 104, 105, 106, 107 shown here are designed as ventilated jet regulators, in the jet regulator housing 7 of which the water flowing through is mixed with ambient air. As can be clearly seen in FIGS. 10, 19, 29, 39, 52, 53 to 55 and 57, the jet regulators 101, 102, 103, 104, 105, 106 and 107 have a jet separator which divides the water flowing through into a plurality disassembled by single beams. This jet breaker is inserted from the inflow side into the sleeve interior of the designed as a joint sleeve wall 3. The jet splitter of the jet regulators 101, 102, 103, 104, 105, 106 and 107 shown here is preferably releasably connected to an attachment or filter screen 12, which is hat-shaped and thus remains within the enveloping circle formed by the pivotability of the wall 3.

The jet splitter is designed here as a pot-shaped diffuser 13 or has such a cup-shaped diffuser 13 which has uniformly spaced apart burying openings 14 in the circumferential direction of the pot periphery of its pot shape. The pot bottom of this pot shape forms a baffle 15, which; the effluent water to the burster openings 14 deflects. In this case, pen-shaped flow obstacles 16, which already divide up the water, protrude beyond the inflow side of the pot base in the area of the burster openings 14. The burster openings 14 open on the outside of the diffuser 13 in an annular gap 17, which is formed between the diffuser 13 and a diffuser ring 18 embracing it. This annular gap 17 tapers in the flow direction, so that the consequent increase in velocity of the water flowing through according to the Bernoulli equation has a negative pressure on the downstream side of the annular gap 17 result. With the help of this negative pressure, ambient air can be sucked into the housing interior of the jet regulator housing 7 and in particular into a mixing chamber 19 arranged between the jet separator and the downstream hole structure 4. The wall 3 has for this purpose in its downstream part of at least one front side open ventilation duct 20. In this case, the ventilation channel 20 bounding inner wall portion forms an inner wall 21, the at least one for Mixing chamber 19 leading ventilation opening 22 has. On the inner wall 21, the hole structure 4 is integrally formed on the downstream side. The serving as a hinge or swivel sleeve wall 3 is inserted from the inflow side of the jet regulator housing 7 in this until the wall 3 reaches the socket 6.

In the jet regulators 101, 102, 103, 104, 106 and 107 shown in FIGS. 1 to 41 and 53, a seal 23, designed here as a ring seal, is provided in the inflow-side partial area of the joint socket 6, said seal between the wall 3 and the wall Housing inner circumference of the jet regulator housing 7 seals. This seal 23 is partially overlapped by a retaining ring 24, which secures the seal 23 on the housing inner circumference of the jet regulator housing 7. The retaining ring 24 is preferably releasably latched on the housing inner circumference of the jet regulator housing 7. The seal 23 and optionally also the retaining ring 24 take in their adjacent to the joint socket 6 portions of the spherical shape of the socket 6 and carry them on. The seal 23 and the retaining ring 24, each having a smaller diameter relative to the maximum outer diameter of the wall 3, secure the wall 3 against high pressures against the flow direction of the jet regulators 101, 102, 103, 104, 106 and 107.

From the figures 42 to 52 can be seen that in the example shown there, the jet regulator 105 between the wall 3 and which serves as a joint socket portion of the jet regulator housing 7, at least: a resilient coating or layer is partially provided 42 relative to each other between ^them. pivotable components 3, 7 of the jet regulator 105 seals. It can be clearly seen in FIGS. 42 to 52 and in particular in the detailed longitudinal section in FIG. 43 that the wall 3 carries on its outer circumference, at least in places, the circumferential elastic layer 42 or coating. In order to simplify the production of the jet regulator 105 shown here, the wall 3 carrying the layer 42 is produced as a two-component or multi-component plastic injection-molded part. As can be seen from a comparison of Figures 45 and 47, the wall of the jet regulator 105 shown here can also be brought into the tilting or open position shown in Figure 45, in which the water flowing through the jet regulator housing 7 through only one, between the Wall 3 and the adjacent Gehäuseinnenumfangswandung formed opening gap 8 flows out of the jet regulator housing 7. In contrast, in the open position shown in FIG. 47, the wall 3 is additionally pivoted or tilted in such a way that this wall 3 is arranged practically in a plane extending through the jet regulator longitudinal axis. In the tilted position of the wall 3 of the jet regulator 105 shown in FIG. 47, the water flowing through the jet regulator housing 7 can flow out of the jet regulator housing 7 through two opening gaps 8, 9 which have formed between the wall 3 and the respectively adjacent subregion of the housing inner circumferential wall.

The jet regulators 101, 102, 103, 104, 105 shown here,

106 and 107 can be attached in various ways to the water outlet 1 of a sanitary outlet fitting 2. Like from the

FIGS. 1 to 12 and FIGS. 42 to 57, a flange 25 is provided on the housing outer circumference of the jet regulator housing 7 of the jet regulator 101, 105, 106 and 107. In the FIGS. 7 and 53 to 57 show by way of example that the jet regulators 101, 105, 106 and 107 can be inserted into a sleeve-shaped outlet mouthpiece 26 which can be mounted on the water outlet 1 of a sanitary outlet fitting 2, until the flange 25 on a support 27 designed as an annular shoulder in the outlet mouthpiece 26 rests. In the jet regulator 101 shown in FIGS. 1 to 12, the outlet mouthpiece 26 has an external thread 28 on its outer circumference, with which the outlet mouthpiece 26 can be screwed into an internal thread in the water outlet 1 of the sanitary outlet fitting 2. In contrast, the outlet nozzle 26 of the jet regulator 106 and 107 shown in Figures 53 to 107 at its outer periphery an internal thread 43, with the outlet nozzle 26 can be screwed into an external thread on a connected to the water outlet 1 of the sanitary outlet fitting 2 adapter 44.

In contrast, the jet regulators 102, 103 and 104 without such an outlet nozzle 26 in the water outlet of a sanitary outlet fitting can be mounted. The jet regulators 102, 103, 104 have for this purpose on the outer circumference of their jet regulator housing 7 itself an external thread 29, with which the jet regulator housing 7 is screwed or screwed to an internal thread in the water outlet of the sanitary outlet fitting. The jet regulators 102 and 103 shown in FIGS. 13 to 31 can be screwed so deeply into the water outlet of the sanitary outlet fitting until the outlet end face of these jet regulators 102, 103 is arranged approximately in a plane with the downstream end edge of the water outlet. The jet regulators 102 and 103 are therefore barely visible in their use position mounted in the water outlet of the sanitary outlet fitting. In order to seal off the annular gap remaining between the jet regulator housing 7 and the inner circumference surrounding the water outlet, an annular groove 30 is provided on the jet regulator housings of the jet regulators 102, 103 in the flow direction below the external threads 28, into which an elastic sealing ring 31 is inserted which forms a radial seal forms. In order to be able to screw in and out the jet regulators 102, 103 in the water outlet of the outlet fitting, these jet regulators 102, 103 have crown-shaped protrusions and indentations 32, 33 on the outlet end face 11, of which the protrusions 32 serve as a tool engagement surface for a turning tool.

In order to be able to seal between the jet regulator housing 7 and the adapter 44 upstream in the inflow direction, a sealing ring 45 is inserted into the outlet mouthpieces 26 of the jet regulators 106 and 107, which rests on the inflow-side end edge of the jet regulators 106 and 107 and between this and the downstream peripheral edge of the jet Adapters 44 seals. The adapter 44 has below an attached to the water outlet of the sanitary outlet fitting 2 thread an annular groove 46 into which also a sealing ring 47 is inserted. This sealing ring 47 seals the annular gap between the inner circumference of the water outlet 1 of the sanitary outlet fitting 2 and the outer circumference of the adapter 44.

The jet regulator housing 7 of the jet regulator 104 shown in FIGS. 32 to 41 is designed similarly to an outlet nozzle. The jet regulator housing 7 of the jet regulator 104 has at its outer circumference an external thread 29, with which the jet regulator housing 7 can be screwed into an internal thread in the water outlet of a sanitary outlet fitting. In the screwed-in position of use, however, the jet regulator housing 7 of the jet regulator 104 continues to be present the majority of its jet regulator housing 7 on the downstream end edge of the water outlet to the sanitary outlet fitting before. The jet regulator housing 7 of the jet regulator 104, which is sealed axially relative to the water outlet by means of a sealing ring 35 arranged on the inflow side, has key engagement surfaces 34 on opposite sides of its outer circumference on which, for example, an open-end wrench not shown here can be attached. The jet regulators 101, 102, 103, 104, 105, 106 and 107 shown here have a handle 10, which is integrally formed on the wall 3 of these jet regulators. While these handles 10 protrude laterally beyond the jet regulator housing 7 in the jet regulators 101, 104, 105, 106 and 107, the handles 10 in the jet regulators 102 and 103 rest laterally relative to the outer circumference of the jet regulator housing 7. To the handle 10 of the jet regulators 102 and 103 is therefore formed in the longitudinal direction of the jet regulators 102, 103 projecting pin 36, with which the handle 10 of the jet regulator 102, 103 can be detected between the fingertips.

In order to secure the wall 3 against unintentional pivoting as a result of acting from the inlet side of the water pressure and the wall 3 of the jet regulators 101, 102, 103, 104, 105, 106 and 107 in the example in Figures 1, 2, 5 , 7, 8, 9, 12, 13, 14, 17, 20, 22, 23, 27, 30, 31, 32, 33, 37, 40, 41, 42, 44, 48, 53, 54, 55 and 57 hold position shown, the wall 3 in this position of use on the jet regulator housing 7 of the jet regulator 101, 102, 103, 104, 105, 106, 107 securable by means of a latching connection.

From a concise consideration of FIGS. 1 to 12 and 42 to 52 it can be seen that in the case of the jet regulators 101, 105 shown there, this latching connection has a latching projection 31 which protrudes on the handle 10 and can be latched to a circumferential latching groove 38 on the housing outer circumference of the jet regulator housing 7.

It can be seen in FIG. 20 that the handle 10 of the jet regulator 102 can be latched to the downstream housing front side of the jet regulator housing. At this downstream housing end face for this purpose at least one locking receptacle 39 is provided, in which the handle 10 of the jet regulator 102 can be latched.

From a comparison of Figures 23, 25, 33, 35 and 53 to 57 it is clear that the jet regulators 103, 104, 106 and 107 in the region between the handle 10 and the spherical layer-shaped outer periphery of the wall 3 have a Rasteinformung 40, which with a can be latched, which is integrally formed on the downstream edge of the joint socket 6 to the jet regulator housing 7.

It is a particular advantage of the jet regulators 101, 102, 103, 104, 105, 106 and 107, that their wall 3 can be rotated thanks to its spherical outer periphery 5 in each rotational position in the socket 6, for example, the handle 10 from the field of view of a user. In this case, the wall 3 by means of the latching connection in each selected rotational position can be locked in such a way that an unintentional release of the wall 3 from the position of use need not be feared. If the wall 3, in contrast, rotated such that the wall 3 is arranged approximately parallel to the jet regulator longitudinal axis, by the jet regulators 101, 102, 103, 104, 105, 106, 107 on one side or on both sides of the wall 3 through the Flow through the opening gaps 8 and 8, 9 and thus also entrain the dirt particles accumulated on the inflow side of the wall 3 in the region of the attachment or filter screen 12 and discharge to the outside. In this way, proper operation of the jet regulators 101, 102, 103 and 104, 105, 106 and 107 is ensured: even over long periods of maintenance:

As is clear from FIGS. 53 to 57, a first flow rate regulator 48 can also be integrated into the jet regulators 106 and 107 shown here. This flow rate regulator is intended to regulate the volume of water flowing through the jet regulator 106, 107 per unit of time to a defined maximum value independently of pressure. For this purpose, the flow rate regulator 48 is preferably detachably held on the inflow-side end face of the jet regulators 106, 107 and in turn carries the attachment filter or filter screen 12. Since the jet regulator 106 or 107 form the upstream flow rate regulator 48 and the attachment or filter screen 12 form a unit , which can be pivoted by means of the spherical-layer-shaped wall 3 between a use position and an open position, the flow rate regulator 48 connected to the jet regulator 106, 107 can no longer fulfill its control function in the open position of the pivotable wall 3. In some countries, however, there are legal requirements according to which the volume of water flowing out of the water outlet of a sanitary outlet fitting per time unit must never exceed a legally stipulated maximum value. In such cases, it may be advantageous if an additional second flow rate regulator 49 is provided in the inflow line to the jet regulator 106, 107 in the flow direction, preferably at a distance from the latter, which measures the volume of water flowing through both the position of use and in the open position of the wall 3 pressure independent to a ■ set maximum value per unit of time regulates. This additional second flow rate regulator 49 is integrated into the sleeve-shaped adapter 44 in the exemplary embodiments 106, 107 shown in FIGS. 53 to 57.

The flow rate regulators 48, 49 used in the exemplary embodiments according to FIGS. 53 to 57 have an annular throttle body 50 or 51 made of elastic material, which has a central control core

52 and 53 surrounds. At the central control core 52,

53 or on the circumferential wall which surrounds the elastic throttle body 50, 51, a control profiling is provided, between which and the throttle body 50, 51 there is a control gap variable under the pressure of the medium flowing through. As the pressure increases, the elastic throttle body 50, 51 is pressed into the control profiles, thereby narrowing the control gap, such that the water volume flowing through per unit time can be regulated to a defined maximum value independently of pressure.

From a comprehensive examination of FIGS. 53 to 56, it becomes clear that the flow rate regulator 49 provided in the adapter 44 has a control core 53 which is displaceably guided in the longitudinal or flow direction. Under the pressure of the inflowing water of this control core 53 against the restoring force of a rubber or elastic return ^¬ stellelements, which is here designed as a compression spring 54, from the standby position shown in Figures 53 and 54 in the control position shown in Figures 55 and 56 emotional. Since the control core 53 of the flow regulator 49 at low water pressures thus still in its ready position is located in the between the elastic throttle body 51 and the control core 53 still a comparatively large annular gap, in this position even larger dirt particles still pass through the flow regulator 49, which are then discharged in the open position of the wall 3 of the jet regulator 106 from the jet regulator housing can. In the embodiment shown in FIG. 57, the flow rate regulator 4 located in the adapter 44 is in contrast designed as a low-pressure flow rate regulator, as already described in the German patent application 10 2006 057 787.6 and the parallel European patent application 07 846 729.7. This low-pressure flow regulator is characterized by a comparatively large control gap, which also allows larger dirt particles to pass through to the jet regulator 107. Even such larger dirt particles can then be removed in the open position of the wall 3 of the jet regulator 107 from the jet regulator housing 7 in a simple manner. It can be seen in FIGS. 37 and 49 that the jet regulator 104 is sealed by means of an elastic sealing ring 35 with respect to the water outlet of the sanitary outlet fitting.

It is clear from FIGS. 42 to 52 that the wall 3 of the jet regulator 105 carrying the layer 42 or coating is secured in the joint socket 6 of the jet regulator housing 7 by means of the retaining ring 24. An additional seal 23, as provided, for example, in the jet regulator 101, is not required with the jet regulator 104 in contrast.

From an overview of FIGS. 41, 44 and 48 to 50 it becomes clear that at least one of the handle 3 at a distance from the handle 10 at the outlet end side of the wall 3 Alignment projection 55 protrudes, which rests in the position of use of the wall 3 on the outlet side end peripheral edge of the jet - regulator housing. In this case, at least one alignment projection 55 is preferably provided on both sides of the handle 10, which alignment projections 55 hold the wall 3 in a plane arranged approximately at right angles to the jet regulator longitudinal axis.
