EP3371384B1 - Jet regulator that can be pivoted into a cleaning position - Google Patents

Description

The invention relates to a jet regulator with a sleeve-shaped jet regulator housing that can be mounted on the water outlet of a sanitary outlet fitting, as well as with a wall which carries a hole structure forming the outlet end face of the jet regulator and which is in the jet regulator housing between a position of use in which the hole structure extends across an outflow side Housing opening of the jet regulator housing extends, and a cleaning position can be pivoted, 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 an adjacent inner circumferential wall of the housing, a handle being provided on the wall, which over the Perimeter or the downstream side of the jet regulator housing protrudes.

From the WO 2014/142766 A1 a jet regulator of the type mentioned is already known. The 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 shape the outflowing water there into a homogeneous and non-splashing water jet. In the jet regulator housing, an annular wall is provided which carries a hole structure forming the outlet end face of the known jet regulator. This ring wall has a stub axle on opposite sides of its outer circumference, which axle stubs are mounted on the inner circumference of the jet regulator housing. The ring wall is pivotably mounted in the jet regulator housing about this stub axle in such a way that the ring wall in the jet regulator housing is between a position of use, in which the hole structure extends across an outflow-side sleeve 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 on both sides of the ring wall through opening gaps formed between the ring wall and the adjacent inner peripheral wall of the housing. In this way, limescale deposits or other dirt particles that have accumulated on the inflow side in front of the hole structure in the water can be rinsed out and carried away from the aerator housing through one of the opening gaps in order to continue to ensure the trouble-free functioning of the aerator. A pin protrudes from the side of the ring wall 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. However, it is disadvantageous that this handle remains clearly visible in most of the relative positions of the jet regulator in the water outlet and can encourage many people to swivel the ring wall without need and, if necessary, to leave it in its cleaning position. In addition, a handle protruding from the water outlet impairs the appearance of the entire sanitary outlet fitting.

From the DE 10 2005 010 550 B4 we already know a jet regulator with a jet regulator housing which has an external thread on its outer circumference of the housing, with which external thread 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 pivotably in a complementarily shaped joint socket on the outflow-side end region of the jet regulator housing on the inner circumference. A perforated plate is provided in the interior of the pivotably mounted joint sleeve. Since the joint sleeve having the perforated plate is pivotably mounted, the outlet direction of the exiting water jet can be at Needs to be changed and realigned. Since the joint sleeve strikes against components of the known jet regulator connected upstream on the inflow side, which also serve as a swivel stop, cleaning of the known jet regulator in the assembled state is neither possible nor intended.

From the US-A-4,457,030 we already know a waste water drain which has a tubular drain body with a plug shaped spherically on the outer circumference, which plug is held pivotably in a complementarily shaped joint socket on the inner circumference of the drain body. The plug can be pivoted between a closed position, in which the plug closes the clear pipe cross-section of the drain body, and an open position, in which open position the draining water can pass through the drain body on both sides past the plug, which is pivoted into the longitudinal axis of the drain body .

There is therefore the particular task of creating a jet regulator of the type mentioned, which can also be easily cleaned in the assembled state, whereby this jet regulator should not significantly impair the external appearance of a sanitary outlet fitting despite being easy to handle, and this jet regulator is by a should distinguish a good outlet jet pattern.

The inventive solution to this problem in the aerator of the type mentioned in particular consists in the fact that the wall has a spherical-layer-shaped outer circumference and, with this spherical-lamellar outer circumference, is pivotably mounted in a joint socket provided on the inner circumferential wall of the aerator housing and at least in a partial area complementarily shaped that the wall is rotatable in the circumferential direction and is pivotably mounted in the joint socket in every rotational position, that the jet regulator is a ventilated jet regulator, in whose jet regulator housing the water flowing through is mixed with ambient air, that the wall has at least one ventilation channel open at the end in its downstream sub-area, that the one delimiting the at least one ventilation channel inner wall section forms an inner wall which has at least one ventilation opening and to which the hole structure is formed in one piece, so that the jet regulator has a jet splitter which divides the water flowing through into a plurality of individual jets and which is designed as a pot-shaped diffuser or has a pot-shaped diffuser, which has decomposition openings on the circumference of its pot shape, and the bottom of which forms a baffle which deflects the incoming water to the decomposition openings, and that the decomposition openings open into an annular gap that opens tapered in the direction of flow.

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 which is designed, for example, as a joint or swivel sleeve and preferably designed as an annular 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 inner circumferential wall of the jet regulator housing. The wall is pivotably mounted with its spherical layer-shaped outer circumference in the joint socket in such a way that this wall in the jet regulator housing between a use position in which the hole structure extends across an outflow-side 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 inner peripheral wall of the housing. Since no stub shafts are provided on the wall of the jet regulator according to the invention, which define 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 in order to remove any disturbing details, such as a protruding handle, from the viewer's field of vision rotate. The wall is rotatable in the circumferential direction and is mounted in the joint socket so that it can be pivoted in every rotational position. Since the wall can be pivoted between the position of use and the at least one cleaning position in any rotational position, the ease of use of the jet regulator according to the invention is further enhanced. So that the user can recognize the cleaning function and possibility as easily as possible, it is provided according to the invention that a handle is arranged on the wall, which protrudes over the circumference or the outflow face of the jet regulator housing. The user can therefore grip the handle in order to then pivot the wall in the jet regulator housing. The user can also control the swiveling process from a distance above the sanitary outlet fitting without having to put his face at the level of the water outlet.

Since the joint socket has a shape complementary to the spherical-layer-shaped wall at least in a partial area, an easy and pressure-free pivotability of the wall in the joint socket is also promoted. Since the jet regulator according to the invention is designed as a ventilated jet regulator, in whose jet regulator housing the water flowing through is mixed with ambient air, can In the jet regulator according to the invention, a homogeneous, non-spraying and pearly soft water jet can be formed. The wall of the jet regulator according to the invention has at least one venting channel open at the end and optionally also designed as an annular gap in its downstream partial area, the inner wall section delimiting the annular gap forming an inner wall which has at least one ventilation opening and to which the hole structure is integrally formed. The wall of the jet regulator according to the invention has at least one venting channel open at the end in its partial area on the outflow side. Ambient air can be sucked into the ventilation duct through the duct opening oriented towards the outflow side, which air then reaches the interior of the housing of the jet regulator according to the invention via the at least one ventilation opening. Since the hole structure is formed in one piece on the inner wall delimiting the ventilation channel, the mobility and the number of components of the jet regulator according to the invention are advantageously limited. The jet regulator according to the invention has a jet splitter which splits the water flowing through into a large number of individual jets. In order to be able to decelerate the inflowing water sufficiently and effectively break it down over a short distance, the invention provides that the jet splitter is designed as a cup-shaped diffuser, which has splitting openings on the circumference of its cup shape and the bottom of which forms a baffle surface that closes the inflowing water diverts the cutting openings. So that the water flowing through the jet splitter in the form of individual jets can subsequently suck in the required ambient air, the jet regulator according to the invention provides that the splitter openings open into an annular gap which tapers in the flow direction. Since the annular gap tapers in the direction of flow, the openings from the splitter incoming individual jets flowing into the annular gap are accelerated in such a way that, according to Bernoulli's equation, a negative pressure is created on the outflow side of the annular gap. As a result of this negative pressure formed on the outflow side of the annular gap, ambient air can be sucked into the interior of the jet regulator housing, where it is mixed with the water flowing through.

A particularly simple embodiment according to the invention provides that the handle is designed in the shape of a pin.

So that the wall does not pivot by itself under the pressure of the inflowing water, it is advantageous if the wall can be secured in the position of use on the jet regulator housing, preferably by means of a latching connection.

Such a locking connection can, for example, have at least one locking projection protruding from the handle, which can be locked to a circumferential locking groove on the outer circumference of the aerator housing or to at least one locking recess provided on the downstream edge of the aerator housing. In particular, a circumferential locking groove on the outer circumference of the housing, which can be locked with a locking projection on the handle, allows the wall to be locked in practically every rotational position in such a way that a handle protruding over the water outlet is also out of view of the user.

It is also possible, however, for the handle to be latchable on the housing end face of the jet regulator housing on the downstream side. For this purpose, at least one latching receptacle, in which the handle can be latched, can be provided on the housing end face on the outflow side.

To be found on the upstream side of the jet splitter To remove accumulating dirt particles, it is advantageous if the jet splitter is held in the wall.

So that such dirt particles cannot get stuck in the splitter openings of the jet splitter, it is advantageous if the jet splitter is connected to an attachment or filter screen on the inflow side. A preferred embodiment according to the invention provides that the jet splitter carries the attachment or filter screen on the inflow side and that the attachment or filter screen is preferably designed in the shape of a hat or plate. In particular, a hat-shaped or plate-shaped attachment or filter screen can be designed in such a way that this attachment or filter screen still remains in the enveloping circle formed or circumscribed by the pivotable wall.

An embodiment according to the invention that is particularly easy to manufacture provides that the annular gap is provided between the diffuser and a diffuser ring encompassing the diffuser.

So that the jet regulator according to the invention can also withstand high water pressures, it is advantageous if the wall can be inserted into the jet regulator housing from the inflow side of the latter.

So that the water flowing through the jet regulator according to the invention flows through the hole structure in the wall and thus undesired leakage flows past this hole structure can be avoided, it is advantageous if a seal, preferably designed as a ring seal, is provided in the upstream portion of the joint socket, which seal is provided between the wall and the inner circumference of the aerator housing.

In order to fix the seal in the aerator housing on the one hand and to make it more difficult on the other hand to push the wall out of the aerator housing undesirably, it is advantageous if a retaining ring is provided which can be latched on the one hand on the inner circumference of the aerator housing and on the other hand secures the seal on the inner circumference of the aerator housing.

In contrast, another preferred embodiment according to the invention provides that between the wall and the sub-area of the jet regulator housing serving as a joint socket, an elastic coating or layer is provided at least in some areas, which seals between these relatively pivotable components of the jet regulator.

In this case, this elastically sealing layer or coating can be provided on the partial area of the jet regulator housing serving as a joint socket. However, an embodiment is preferred in which the wall carries the circumferential elastic layer or coating on its outer circumference, at least in some areas.

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

An embodiment according to the invention provides that the jet regulator housing has a ring shoulder or an annular flange on its outer circumference and that the jet regulator can be inserted into a sleeve-shaped outlet mouthpiece that can be mounted on the water outlet of a sanitary outlet fitting until the annular shoulder or ring flange on a support in the outlet mouthpiece strikes or rests.

According to another proposal according to the invention, it is provided that the jet regulator housing has an external thread on its outer circumference, with which external thread the jet regulator housing can be screwed or screwed into 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 in a simple manner at time intervals, it is advantageous if, in the cleaning position, the water flowing through the jet regulator housing can optionally flow out of the jet regulator either through an opening gap formed on one side of the wall or through an opening gap formed on both sides of the wall.

It is a particular advantage of the jet regulator according to the invention that the wall in the form of a spherical layer on its outer circumference is pivotably mounted in a joint socket without stub axles having to be provided on the outside of this wall. In order to bring the wall in its position of use into a position oriented almost at right angles to the longitudinal axis of the jet regulator, it is advantageous if at least one alignment projection protrudes on the outflow side of the wall, which in the use position of the wall rests on the outflow face of the jet regulator housing. By means of this at least one alignment projection, an undesired tilting position of the wall in the position of use is avoided, which could otherwise lead to an undesirable inclined outflow of the outflowing water.

The handling of the jet regulator according to the invention and the alignment of its wall in the position of use is significantly facilitated if at least two alignment projections protrude on the wall, which are on both sides of the handle and are arranged at preferably equal distances from the handle on the outflow face of the wall.

In order to be able to limit the water consumption in an advantageous manner with the aid of the jet regulator according to the invention, it is advantageous if the jet regulator is preferably detachably connected to a flow regulator on its inflow end, which flow regulator regulates the volume of water flowing through the jet regulator to a fixed maximum value per unit of time, independent of pressure . With the help of this flow rate regulator, it is avoided that the water volume flowing through the wall in the position of use through the jet regulator according to the invention exceeds a fixed maximum value when the water pressure of the incoming water continues to increase.

In an embodiment of the jet regulator according to the invention with an attachment or filter screen connected upstream on the inflow side, it is advantageous if an attachment or filter screen is held, in particular releasably, on the flow rate regulator. In this preferred embodiment, the unit formed from the jet regulator, the flow rate regulator and the inflow-side attachment screen can be pivoted with the aid 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 tap fitting per unit of time must not exceed a legally stipulated limit value. In an embodiment in which the jet regulator according to the invention carries the flow rate regulator, this flow rate regulator cannot fulfill its function in the open position of the wall. In order to be able to meet the legal requirements in the open position of the wall of the jet regulator according to the invention, one embodiment according to the invention provides that in the

(This is followed by the original pages 12 to 34 of the description including the original list of reference symbols)

Inflow line to the jet regulator in the flow direction, preferably at a distance therefrom, an optionally also additional flow rate regulator is provided, which regulates the flowing water volume independently of pressure to a possibly also legally specified maximum value per unit of time.

Developments according to the invention emerge from the description in conjunction with the claims and the drawing. The invention is described in more detail below with reference to preferred exemplary embodiments.

one with the embodiment according to the Figures 53 to 56 Comparably designed variant, which, however, has in the adapter a flow rate regulator which regulates even at low pressures and has such a large regulating gap that dirt particles can also pass through this regulating gap.

In the Figures 1 to 41 seven embodiments 101, 102, 103, 104, 105, 106 and 107 of a jet regulator are shown. As in Figure 7 shown by way of example, the jet regulator versions 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 hinge or swivel sleeve and designed as an annular wall, is pivotably mounted with its spherical layer-shaped outer circumference 5 in a joint socket 6, which is provided on the inner circumference of the housing of a jet regulator housing 7. The wall 3 with its spherical layer-shaped outer circumference 5 is pivoted in the joint socket 6 in such a way that this wall 3 can be pivoted in the jet regulator housing 7 between a position of use, in which the perforated structure 4 extends transversely over an outflow-side housing opening of the jet regulator housing 7, and a cleaning position, in which the water flowing through the jet regulator housing 7 passes through at least one between the wall 3 and the adjacent one The opening gap 8 or 8, 9 formed in the inner peripheral wall of the housing can flow out of the jet regulator housing 7. Since no stub shafts are provided on the wall 3 of the jet regulators 101, 102, 103, 104, 105, 106, 107 that define the pivot axis of this wall 3 in the jet regulator housing 7, the wall 3 in the joint socket 6 can also be rotated in the circumferential direction in order to turn any disturbing details, such as a handle protruding from the side, out of the viewer's field of vision.

The joint socket 6 molded into the inner circumference of the jet regulator housing 7 has, at least in a partial area, a shape that is complementary to the outer circumference 5 of the wall 3 in the form of a spherical layer. The wall 3 with its spherical-layer-shaped outer circumference 5 is rotatable in the circumferential direction in the complementarily shaped joint socket 6 and is mounted in the joint socket 6 so that it can be pivoted in every rotational position.

In order to facilitate the handling of the jet regulator 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, which extends laterally over the circumference of the jet regulator housing 7 or protrudes over the outlet end face 11. This handle 10 can be designed in the shape of a pin.

The jet regulator designs 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 in the Figures 10 , 19th , 29 , 39 , 52 , 53 to 55 and 57 As can be clearly seen, the jet regulators 101, 102, 103, 104, 105, 106 and 107 have a jet splitter which splits the water flowing through into a large number of individual jets. This jet splitter is inserted from the inflow side into the sleeve interior of the wall 3 designed as a joint sleeve. The jet splitter of the jet regulators 101, 102, 103, 104, 105, 106 and 107 shown here is preferably detachably 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 cup-shaped diffuser 13 or has such a cup-shaped diffuser 13 which has splitter openings 14 that are evenly spaced apart from one another in the circumferential direction on the cup circumference of its cup shape. The bottom of this pot shape forms a baffle 15 which deflects the outflowing water to the cutting openings 14. In this case, pin-shaped flow obstacles 16, which already divide the water, protrude over the inflow side of the bottom of the pot in the area of the splitting openings 14. The splitting 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 that encompasses it. This annular gap 17 tapers in the flow direction, so that the resulting increase in the speed of the flowing water, according to Bernoulli's equation, results in a negative pressure on the outflow side of the annular gap 17. With the aid of this negative pressure, ambient air can be sucked into the interior of the jet regulator housing 7 and, in particular, into a mixing chamber 19 arranged between the jet splitter and the perforated structure 4 on the downstream side.

For this purpose, the wall 3 has at least one ventilating channel 20 open at the end in its downstream partial area. The inner wall section delimiting the ventilating channel 20 forms an inner wall 21 which is at least one towards the Has mixing chamber 19 leading ventilation opening 22. The perforated structure 4 is integrally formed on the inner wall 21 on the outflow side.

The wall 3 serving as a hinge or swivel sleeve can be inserted into the jet regulator housing 7 from the inflow side until the wall 3 reaches the joint socket 6.

In the Figures 1 to 41 and 53 to 57 For the jet regulators 101, 102, 103, 104, 106 and 107 shown, a seal 23, here designed as a ring seal, is provided in the upstream part of the joint socket 6, which seals between the wall 3 and the inner circumference of the jet regulator housing 7. This seal 23 is overlapped in some areas by a retaining ring 24, which secures the seal 23 on the inner circumference of the jet regulator housing 7. The retaining ring 24 is preferably releasably latched on the inner circumference of the jet regulator housing 7. The seal 23 and possibly also the retaining ring 24 take up the spherical shape of the joint socket 6 in their subregions adjoining the joint socket 6 and guide it further. The seal 23 and the retaining ring 24, which each have a smaller inside diameter than the maximum outer diameter of the wall 3, secure the wall 3 against being pushed up against the flow direction of the jet regulators 101, 102, 103, 104, 106 and 107.

From the Figures 42 to 52 It can be seen that in the jet regulator 105 shown there between the wall 3 and the sub-area of the jet regulator housing 7 serving as a joint socket, an elastic coating or layer 42 is provided at least in some areas, which between these relatively pivotable components 3, 7 of the jet regulator 105 seals. It is in the Figures 42 to 52 and in particular in the detail longitudinal section in Figure 43 It can be clearly seen that the wall 3 carries the circumferential elastic layer 42 or coating on its outer circumference, at least in some areas. In order to simplify the manufacture of the jet regulator 105 shown here, the wall 3 carrying the layer 42 is manufactured as a two-component or multi-component plastic injection-molded part.

As from a comparison of the Figures 45 and 47 can be seen, the wall of the jet regulator 105 shown here can also be inserted in the manner shown in FIG Figure 45 Tilt or open position shown are brought in which the water flowing through the jet regulator housing 7 flows out of the jet regulator housing 7 through only one opening gap 8 formed between the wall 3 and the adjacent inner peripheral wall of the housing. In contrast, the wall 3 in the in Figure 47 The open position shown is additionally pivoted or tilted in such a way that this wall 3 is practically arranged in a plane running through the longitudinal axis of the jet regulator. In the in Figure 47 The tilted position of the wall 3 of the jet regulator 105 shown in the figure, 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 sub-area of the inner peripheral wall of the housing.

The jet regulators 101, 102, 103, 104, 105, 106 and 107 shown here can be fastened in various ways to the water outlet 1 of a sanitary outlet fitting 2. As from the Figures 1 to 12 and the Figures 42 to 57 becomes clear, a flange 25 is provided on the outer circumference of the jet regulator housing 7 of the jet regulator 101, 105, 106 and 107. In the Figures 7 and 53 to 57 It is shown by way of example that the jet regulators 101, 105, 106 and 107 can be inserted into a sleeve-shaped outlet mouthpiece 26 that can be mounted on the water outlet 1 of a sanitary outlet fitting 2 until the flange 25 rests on a support 27 in the outlet mouthpiece 26, which is designed here as an annular shoulder. In the case of the in Figure 1 to 12 The jet regulator 101 shown 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 mouthpiece 26 in the Figures 53 to 57 The jet regulator 106 and 107 shown has an internal thread 43 on its outer circumference, with which the outlet mouthpiece 26 can be screwed into an external thread on an adapter 44 connected to the water outlet 1 of the sanitary outlet fitting 2.

In contrast, the jet regulators 102, 103 and 104 can be mounted without such an outlet mouthpiece 26 in the water outlet of a sanitary outlet fitting. The jet regulators 102, 103, 104 have on the outer circumference of their jet regulator housing 7 themselves an external thread 29, with which the jet regulator housing 7 can be screwed or screwed into an internal thread in the water outlet of the sanitary outlet fitting. The ones in the Figures 13 to 31 The jet regulators 102 and 103 shown can be screwed deeply into the water outlet of the sanitary outlet fitting until the outlet face of these jet regulators 102, 103 is approximately in one plane with the downstream edge of the water outlet. The jet regulators 102 and 103 are therefore hardly visible in their position of use in the water outlet of the sanitary outlet fitting.

In order to seal the annular gap remaining between the jet regulator housing 7 and the inner circumference bordering the water outlet, an annular groove 30 is provided on the jet regulator housings of the jet regulator housings below the external thread 28 in the direction of flow, into which an elastic sealing ring 31 is inserted, which provides a radial seal forms. In order to be able to screw the jet regulators 102, 103 in and out of the water outlet of the outlet fitting, these jet regulators 102, 103 are provided with crown-shaped protrusions 32, 33 on the outlet face 11, of which the protrusions 32 serve as a tool contact surface for a turning tool.

In order to be able to seal between the jet regulator housing 7 and the adapter 44 connected 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 upstream front edge of the jet regulators 106 and 107 and between this and the downstream front peripheral edge of the Adapter 44 seals. The adapter 44 has an annular groove 46 below a thread held at the water outlet of the sanitary outlet fitting 2, into which a sealing ring 47 is likewise 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 Figures 32 to 41 The jet regulator 104 shown is designed similarly to an outlet mouthpiece. The jet regulator housing 7 of the jet regulator 104 also has an external thread 29 on its housing outer circumference, 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, the jet regulator housing 7 of the jet regulator 104 is still with it the predominant part of its jet regulator housing 7 over the downstream end edge of the water outlet on the sanitary outlet fitting. The jet regulator housing 7 of the jet regulator 104, which is axially sealed against 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 of the housing, on which, for example, a spanner 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 molded onto the wall 3 of this jet regulator. While these handles 10 in the jet regulators 101, 104, 105, 106 and 107 protrude laterally beyond the jet regulator housing 7, the handles 10 in the jet regulators 102 and 103 remain laterally behind the outer circumference of the jet regulator housing 7. A pin 36 protruding in the longitudinal direction of the jet regulators 102, 103, with which the handle 10 of these jet regulators 102, 103 can be grasped between the fingertips, is therefore formed on the handle 10 of the jet regulators 102 and 103.

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

From looking at the Figures 1 to 12 and 42 to 52 it can be seen that this latching connection in the jet regulators 101, 105 shown there has a latching projection 37 protruding on the handle 10, which can be latched to a circumferential latching groove 38 on the outer circumference of the jet regulator housing 7.

In Figure 20 it can be seen that the handle 10 of the jet regulator 102 can be latched on the outflow-side housing end face of the jet regulator housing. For this purpose, at least one latching receptacle 39 is provided on this housing end face on the outflow side, in which the handle 10 of the jet regulator 102 can be latched.

From a comparison of the Figures 23, 25 , 33, 35 and 53 to 57 It becomes clear that the jet regulators 103, 104, 106 and 107 in the area between the handle 10 and the spherical layer-shaped outer circumference of the wall 3 have a latching recess 40 which can be latched with a circumferential latching projection 41 which is attached to the aerator housing on the downstream edge of the joint socket 6 7 is molded.

It is a particular advantage of the jet regulators 101, 102, 103, 104, 105, 106 and 107 that their wall 3, thanks to their spherical layer-shaped outer circumference 5, can be rotated into any rotational position in the joint socket 6, for example to move the handle 10 out of the field of view of a To bring the user. The wall 3 can be locked in any selected rotational position by means of the locking connection in such a way that there is no need to fear an unintentional detachment of the wall 3 from the position of use. If, on the other hand, the wall 3 is rotated in such a way that the wall 3 is arranged approximately parallel to the longitudinal axis of the jet regulator, this can be achieved 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 opening gaps 8 or 8, 9 and thus also entrain the dirt particles that have accumulated on the inflow side of the wall 3 in the area of the attachment or filter screen 12 and carry them away 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 maintenance intervals.

As from the Figures 53 to 57 As becomes clear, 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, independently of pressure, to a fixed maximum value. For this purpose, the flow rate regulator 48 is preferably detachably held on the upstream end of the jet regulators 106, 107 and in turn carries the attachment or filter screen 12. Since the jet regulator 106 or 107, the flow rate regulator 48 upstream of the inflow side and the attachment or filter screen 12 form a unit that can be pivoted between a use position and an open position by means of the spherical layer-shaped wall 3, 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 unit of time must under no circumstances exceed a legally stipulated maximum value. In such cases, it can 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 therefrom, which regulates the volume of water flowing through both in the use position as well as in the open position of the wall 3, independently of pressure, regulates to a fixed maximum value per unit of time. This additional second flow rate regulator 49 is in the Figures 53 to 57 The exemplary embodiments 106, 107 shown are integrated into the sleeve-shaped adapter 44.

The in the embodiments according to Figures 53 to 57 The flow rate regulators 48, 49 used have an annular throttle body 50 and 51, respectively, made of elastic material, which surrounds a central control core 52 and 53, respectively. A regulating profile is provided on the central regulating core 52, 53 or on the circumferential wall encompassing the elastic throttle body 50, 51, between which and the throttle body 50, 51 there is a regulating gap that can be changed under the pressure of the flowing medium. As the pressure increases, the elastic throttle body 50, 51 is pressed into the control profiles and the control gap is narrowed in such a way that the volume of water flowing through per unit of time can be regulated to a specified maximum value independent of pressure.

From looking at the Figures 53 to 56 it becomes clear that the flow rate regulator 49 provided in the adapter 44 has a control core 53 which is guided displaceably in the longitudinal or flow direction. Under the pressure of the inflowing water, this control core 53 is counteracted by the restoring force of a rubber or spring-elastic restoring element, which is designed here as a compression spring 54, from which in the Figures 53 and 54 ready position shown in the Figures 55 and 56 Shown control position moved. Since the control core 53 of the flow rate regulator 49 is still in its standby position at low water pressures is located, in which a comparatively large annular gap still remains between the elastic throttle body 51 and the regulating core 53, larger dirt particles can also pass through the flow rate regulator 49 in this position, which are then discharged from the jet regulator housing in the open position of the wall 3 of the jet regulator 106 can. The in Figure 57 In contrast, the embodiment shown, the flow rate regulator 49 located in the adapter 44 is 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 was previously described. This low-pressure flow regulator is characterized by a comparatively large regulating gap, which also allows larger dirt particles to pass through to the jet regulator 107. Such larger dirt particles can then be easily removed from the jet regulator housing 7 in the open position of the wall 3 of the jet regulator 107.

In the Figures 37 and 49 it can be seen that the jet regulator 104 is sealed off from the water outlet of the sanitary outlet fitting by means of an elastic sealing ring 35.

From the Figures 42 to 52 it becomes clear 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. On the other hand, an additional seal 23, as is provided for example in the jet regulator 101, is not required in the jet regulator 104.

From looking at the Figures 41 , 44 and 48 to 50 it becomes clear that at a distance from the handle 10 on the outlet end face of the wall 3 at least one Alignment projection 55 protrudes, which in the position of use of the wall 3 rests on the outlet-side front 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 longitudinal axis of the jet regulator.
