Description

aerator

The present invention relates to a jet regulator, which is optionally switchable between at least two outlet jet images and which has a Strahlreglergehäuse with at least two relatively rotatable housing parts, of which an inflow-side first housing part at the water outlet of a sanitary outlet fitting is rotatably tinted and of which a äbströmseitiges second housing part at least at its downstream side

Housing outer circumference formed as a handle or: is connected to a handle, wherein the first housing part has a jet splitter with multiple Zerlegeröffnungen, wherein the Gehäuseinnenumfäng of the second housing part spaced beam channels are provided, and wherein the coming of the Zerlegeröffnungen individual jets in a first rotational position of the housing parts through guided the jet channels and formed into an annular circumferential outlet jet pattern and deflected in a second rotational position in the housing interior of the jet regulator to a central outlet opening of the jet regulator housing.

From the US 2014/0300010 AI already a sanitary inserting unit is already known, which can be used in a sleeve-shaped outlet nozzle, so as to be mounted on the water outlet of a sanitary outlet fitting. The previously known insertion unit has an inflow-side attachment or filter screen for filtering out the dirt particles possibly entrained in the inflowing water, as well as a downstream jet regulator of the type mentioned in the introduction, which can be manually switched between two outlet jet images. While one exit jet pattern provides a spray jet formed by a number of individual jets, the other exit jet pattern of the prior art jet regulator is a voluminous vented discharge jet. Between the upstream header or filter screen and the downstream jet regulator is a flow rate regulator in the. previously known insertion unit, which is intended to adjust the amount of water flowing through to a maximum value independent of the water pressure per unit of time.

The previously known insertion unit, and in particular its jet regulator switchable between two outlet jet patterns, are comparatively complicated in design and manufacture. In addition, the discharge jet images generated in the prior art insertion unit are still relatively dirty and unstable.

US Pat. No. 7,017,837 B2 discloses a jet regulator which can likewise be switched between a ventilated overall jet and a spray jet formed from a number of individual jet streams. This previously known jet regulator is comparatively expensive in its construction and production. There is therefore a particular object to provide a jet regulator of the type mentioned, which can be produced with relatively little effort and which is characterized by clearly distinguishable from each other and in itself stable outgoing jet images.

A erfindüngsgemäße solution to this problem provides that between the first and the second housing part a rotary indexing is provided with at least one locking tooth, the at least one of the jet channels is formed on a housing wall of the jet regulator housing and cooperates with a latching profiling, which is arranged on a circumferential wall of the first housing part, that at least one, the ratchet tooth-bearing portion of the channel wall of at least a jet channel and / or at least a portion of the locking profiling bearing wall of the first housing part is designed as a spring tongue, and that on the second housing part downstream a extending over the central outlet opening grid or network structure is integrally formed.

The jet regulator according to the invention, which can be mounted alone or as part of a sanitary inserting unit at the water outlet of a sanitary outlet fitting, can be switched between at least two outlet jet patterns. For this purpose, the jet regulator according to the invention has a jet regulator housing with at least two housing parts which can be rotated relative to one another. While an inflow-side first housing part on the water outlet of a sanitary outlet fitting is rotatably mounted, a downstream second housing part is formed at least on its downstream: housing outer circumference as a handle or connected to a handle, so that the second housing part there; detected and can be rotated relative to the first housing part. The first housing part has a jet separator which has a number of Zerlegeröffnungen in which the inflowing water is divided into a corresponding number of individual jets. On the housing inner circumference of the second housing part spaced jet channels are provided, wherein the individual jets coming from the Zerlegeröffnungen guided in a first rotational position of the housing parts through the beam channels and to a ring-shaped. current outflow jet image are formed while coming from the Zerlegeröffnungen individual jets are deflected in a second rotational position in the housing interior of the jet regulator to a central: outlet opening of the jet regulator housing. In order to be able to select and differentiate between the outlet jet images, a rotary indexing is provided between the first and the second housing part. This rotation grid has at least one latching tooth, which is formed on a housing wall of the jet regulator housing facing channel wall of at least one of the jet channels. The at least one latching tooth cooperates with a latching profile, which is arranged on a circumferential wall of the first housing part. The housing parts of the jet regulator according to the invention can therefore be precisely aligned with one another, so that the flow paths leading to a defined outlet jet pattern inside the housing of the jet regulator housing can be exactly maintained. In this case, a lattice or network structure extending over the central outlet opening is integrally formed on the second housing part on the outflow side. With the aid of this outlet-side grid or net structure, the water emerging via the central outlet opening can be formed into a homogeneous, non-spraying total jet. Since the at least one, radially inwardly projecting locking tooth is integrally formed on a part of the channel wall of the at least one jet channel designed as a spring tongue, the downstream second housing part can also be produced in a simple manner as an injection molded part and in particular as a plastic injection molded part, wherein during demoulding of the second Housing parts which can compress at least one, a locking tooth bearing spring tongue. In addition or instead, however, at least a portion of the wall of the first housing part carrying the detent profiling may also be designed as a spring tongue, which likewise has a Locking the at least one latching tooth in the locking profiling can be noticeably easier,. whereby the rotational positions of the housing parts are easy to feel and easy to distinguish from one another. The jet regulator according to the invention is therefore characterized by its ease of manufacture and by clearly distinguishable, inherently stable discharge jet images.

In order to be able to clearly perceive each of the detent positions corresponding to an outlet jet pattern during manual rotation of the second housing part relative to the first housing part, it is advantageous if in each case one detent cam is provided on at least two, preferably four and in particular all beam channels.

It can be advantageous if the annular circulating outflow jet pattern from the jet regulator according to the invention expires as an annular wall formed from water. However, a Ausführüngsform according to the invention, in which the annular orbiting outflow jet image is formed by, arranged on a circular path and separated from each other separated from the Strähle individual jets is preferred. By arranged on a circular path individual beams, a spray jet is generated. Thus, the optionally provided on each of a spring tongue locking teeth can be easily deflected and rebound, it is advantageous if the spring tongue of at least one jet channel on both sides

Wall sipes are separated from the adjacent channel side walls.

To the jet regulator according to the invention in a simple manner from the one: outlet jet image to the other outlet jet image to be able to change without having to pay attention to the direction of rotation, it is. advantageous if the first and the second rotational position associated outlet jet images alternate with each detent position of the rotation grid. In this way, the second housing part can be rotated relative to the first housing part in one or the other direction of rotation, with the latching positions corresponding in each case to one outlet jet pattern alternating. In order to provide a smooth, yet reliable rotary indexing between the housing parts, it is advantageous if the latching profiling provided on the circumferential wall of the first housing part has circling cams arranged next to one another in the circumferential direction, of which two adjacent cams each delimit latching formation between them , In this Rasteinformungen the at least one locking tooth of the rotation grid can easily engage, whereby the corresponding rotational position is secured. In order to improve the ease of rotation, it may be advantageous if each, each a detent cam-bearing portion of the wall is designed as a spring tongue and if wall incisions are provided between adjacent spring tongues in the region of each Rasteinformung.

In this case, a secure and accurate engagement of the Drehrasterung is favored in each individual detent position when the radii of profiling rounding and locking cams match approximately.

Another solution to the above task that takes place. or in addition to the embodiments already described above can be realized on a jet regulator according to the invention, provides that the jet splitter has two jet splitter subregions, of which a central first jet splitter subregion is pot-shaped, and that the central first jet regulator subregion is connected to a second jet disperger subregion configured as a circumferential annular flange or annular shoulder is, in which the burster openings are provided.

In this further embodiment according to the invention, for which self-protection is also claimed, the jet splitter has two jet splitter subregions, of which a central first jet splitter sub-region is designed as a cup-shaped calming zone in which the incoming water is decelerated and over the peripheral wall of this pot shape is deflected in the radial direction to the second beam splitter portion, wherein the second beam splitter portion is formed as an annular shoulder or annular flange, in which the Zerlegeröffnungen the Strahlzerlegers are provided.

A stable and uniform discharge jet pattern is favored if the burster openings are evenly distributed around the second jet disintegrator section.

A particularly good deceleration effect of the water flowing to the jet regulator according to the invention is favored when the pot-shaped first jet-separator sub-region is formed hole-free.

In order to reduce the low design and manufacturing costs even further, it is advantageous if the jet splitter is integrally connected to the inflow-side first housing part. A preferred embodiment according to, the invention provides that the second housing part is sleeve-shaped at least in its inflow-side portion

In order to be able to rotate the first and the second housing part of the jet regulator housing in a simple manner relative to one another and nevertheless securely connect it, it is advantageous if the first and the second housing part are releasably connectable to one another, preferably latchable to one another.

A space-saving and compact construction of the jet regulator according to the invention is favored when the pot-shaped first jet-separating partial region of the first housing part projects into the sleeve interior of the second housing part.

By rotating the two housing parts relative to one another, the burster openings of the jet breaker provided in the first housing part are aligned in their relative position to the channel openings of the jet channels provided in the second housing part. While the burster openings are arranged in a latching position corresponding to the first rotary position above the channel openings of the jet channels, these burster openings are aligned in the second rotational position of the housing parts on the remaining between the jet channels clearance or longitudinal gap in the housing interior of the jet regulator housing. In this case, the water guided through the free spaces remaining between the jet channels can be deflected into a central section in the housing interior of the jet regulator housing in order to emerge from there as a possibly also aerated overall jet from the jet regulator housing. In order to be able to separate the flow paths in the housing interior of the jet regulator housing associated with each outlet spray pattern without these flow paths having to be sealed off from one another, it is advantageous if an inner sleeve is provided in the second housing part whose outlet end face forms the central outlet opening.

So that by the inventive. Jet controller flowing water in the housing interior of the jet regulator housing in one of the rotational positions in the central first jet regulator portion can be performed, it is advantageous if deflection bevels are provided on the inner circumference of the second housing part, which formed in the Zerlegeröffnungen individual jets in at least a second rotational position of the housing parts deflect in the direction of the central first jet regulator portion.

A preferred embodiment according to the invention provides that at least one flow divider is provided on at least one deflection bevel, which divides at least one flow divider the water flowing along the deflection slope into partial flows. The flow dividers provided in at least one of the deflecting bevels and preferably in all deflection slopes divide the water flowing past them into at least two partial flows, which are subsequently further divided at the flow obstacles following in the flow direction.

It is particularly advantageous if the at least one flow divider protrudes in a fin shape over the at least one deflection oblique.

The over the deflection slopes towards the central first Jet controller TeilbereiGh deflected water arrives there at a comparatively high speed, which now must first be reduced before the water flowing through the jet regulator according to the invention water can be shaped in the desired manner and: changed. In order to decelerate in its speed on the downstream side of the Umlenkschrägen-, it is advantageous if spaced apart pin or web-shaped flow obstacles are provided on the downstream side of the Umlenkschrägen.

In this case, an advantageous embodiment according to the invention provides that the pot-shaped jet disintegrator has pins or cones spaced apart from one another on the outflow side of its pot bottom, which form pin-shaped flow obstacles. Since the pins or pegs provided on the outflow side of the jet separator form pin-shaped flow obstacles through which the water coming from the deflecting slopes has to pass, the velocity of the water between these pin-shaped obstacles is effectively reduced.

In this case, a preferred embodiment according to the invention provides that the pins or cones to taper preferably tapered towards its downstream pin or pin end and / or that the pin or pin end of the pins or pins is rounded.

In order to additionally reduce the speed of the water guided by the pins or cones, it is advantageous if a central pot bottom portion protrudes on the pot bottom of the pot-shaped Strahlzerlegers and / or if the pot bottom of the pot-shaped Strahlzerlegers at least: on its Outflow side is formed step-shaped. In order for the jet regulator according to the invention can be made comparatively compact, it is advantageous if the pin or pin ends of the pins or pins are arranged approximately in a plane.

An additional reduction in the speed of the water flowing through the housing interior of the jet regulator housing is achieved if in the sleeve interior of the second housing part in the flow direction below the Umlenkschrägen at least one grid or network structure is provided with each other at crossing nodes webs, the flow holes between them and the are provided as web-shaped flow obstacles.

For the same purpose, it may be advantageous if at least one insert part can be inserted into the sleeve interior of the second housing part, which is designed as a grid or network structure or has a grid or network structure.

In order that the respective outflow jet images can be changed with the changes in the rotational positions, it is advantageous if a deflection bevel is provided between adjacent jet channels.

In order for the water deflected by the deflecting bevels to pass through the pen or web-shaped flow obstacles provided there, it is advantageous if the at least one deflecting slope has a deflection bevel outlet which opens below the jet splitter in the sleeve interior of the second housing part ,

In order to achieve an additional speed reduction of the It is advantageous if at least one of the deflecting bevels has at least one preferably flow or fin-type flow divider in the region of its deflection bevel outlet.

In order for the jet regulator according to the invention to be subjected to high loads even without loss of function of its components, it is advantageous if the pot-shaped jet disintegrator has a central support pin on the pot base on the pot inner side, which with its spigot end oriented counter to the flow direction forms an inflow-side component and especially a flow regulator supported.

In order to form the circular orbiting outflow jet image by spray jets that are visibly separated from one another, it is advantageous if spray nozzles are connected downstream of the jet channels in the flow direction and if the spray nozzles preferably open in the outflow-side subregion of the jet regulator housing.

In order to form the more or less whirled-up water in the interior of the jet regulator into a homogeneously outflowing jet, it is advantageous if at least one annular insert is provided between the jet channels and the spray nozzles and has a grid or network structure serving as a flow straightener. So that the function of this grid or network structure is further favored as a flow straightener, it is advantageous if the wall sections delimiting the grid or network openings have a higher longitudinal extent in the direction of flow compared to the opening width of these grid or network openings.

It provides a particularly advantageous embodiment according to The invention provides that the grid structure of the ring insert is formed by preferably radial webs, which limit flow holes as grid openings between them. In order for the individual jets forming the annular peripheral outflow jet pattern to form a conically widening outflow jet pattern, it is advantageous if at least one inner subregion of the peripheral walls bounding the spray nozzles is directed obliquely outwards.

In this case, a particularly simple and easily manufacturable embodiment according to the invention, that the inner sleeve is integrally formed in the second housing part. The guided through the inner sleeve water can be well formed into a homogeneous and non-squirting overall jet when the outlet end of the inner sleeve forming the central outlet opening and designed as a grid or network structure is formed by webs crossing at intersection nodes and delimiting between them outlet openings.

A further solution of the above object, which may also be realized instead of the embodiments described above or in addition to the features described above, provides that the individual jets formed in the burster openings in at least a first rotational position of the housing parts against the outer wall of the Beam channels are guided, and that in relation to the

Beam regulator longitudinal axis at least one of the channel walls and preferably the inner channel wall of the Zerlegeröffnungen is oriented obliquely outwards.

In this invention proposal that is in the beam splitter divided and guided by the Zerlegeröffnungen water from there directed as a single jets against the outer channel wall of the jet channels to flow from there at least initially as a ring to each other arranged individual jets to Strahlreglerauslauf.

In this case, a clean and stable outflow jet image is additionally favored when the jet channels are arranged in an annular gap between the outer circumference of the inner sleeve and the housing inner circumference of the jet regulator housing.

In order for the individual jets emerging from the jet channels to form an outgoing jet image forming an annular wall inside the housing or for the individual jets to emerge from the jet regulator according to the invention as individual spray jets arranged annularly relative to one another, it is advantageous if the jet channels are in an outlet-side subarea of the jet regulator housing and if this outlet-side partial region has a clear housing cross-section which widens in the outlet direction. In this embodiment, the jet channels still open in the housing interior of the jet regulator housing in an outflow-side subarea, where they can combine, for example, into a ring wall formed from a thin water band. Since the outlet-side portion has a widening in the outlet direction clear housing cross section, this annular wall spreads after emerging from the jet regulator housing still slightly, whereby this ring wall is maintained over a relatively long distance of the exiting water jet without the water to a dirty and Uneven spray pattern coincides.

The stability of the individual spray jets or the here from The annular wall formed the individual jets is maintained even after exiting the jet regulator housing over a comparatively ^¬ long path when profiling is provided on the inside circumferentially ^¬ outgoing part of the jet regulator housing, which is formed by oriented in the flow direction inputs and formations. These indentations and formations on the housing inner circumference of the jet regulator housing mean that the annular wall formed by the water is maintained over a relatively long distance as a constant water film. In order for the outflow jet pattern formed on the housing inner circumference of the jet regulator housing to emerge particularly cleanly from the jet regulator according to the invention, it is advantageous if the jet regulator slide has a spoiler lip on the inner circumference of its outlet side portion.

A homogenization of the jet pattern over a large pressure range is favored if the jet regulator is part of a sanitary inserting unit and if the flow regulator is preceded by a flow regulator or a flow restrictor.

In this case, a particularly compact and space-saving design is favored if the flow rate regulator or the flow restrictor can be used up to a support in the first housing part.

The flow rate regulator or the flow restrictor can be accommodated secured in the housing interior of the jet regulator housing and in particular the inflow-side first housing part, if the flow rate regulator or the flow restrictor is preceded by a header or filter, which is preferably releasably fixable on the first housing part. This intent or filter has to filter out the lime or the like dirt particles possibly contained in the inflowing water, which could otherwise impair the function of the inserting unit and also of its jet regulator.

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

The insertion units 1, Γ have an inflow-side attachment or filter screen 3, 3 'which has to filter out the lime or dirt particles contained in the inflowing water, which otherwise settle in the insertion units 1, 1' and their functions could affect. In order to be able to regulate the amount of water flowing through the inserting units 1, 1 'per unit of time to a fixed maximum value, a flow rate regulator 4, 4' is arranged between the header or filter screen 3, 3 V and the jet regulator 2, 2 '. In order to be able to switch between two outlet jet patterns, the jet regulator 2, 2 'of the insertion units 1, 1' has at least two housing parts 5, 6 rotatable relative to one another; 5 ', 6'.

The second housing part 6, 6 'is sleeve-shaped at least in its inflow-side portion. The first and second housing parts 5, 6; 5 '6' are releasably locked together, wherein the integrally connected to the beam splitter 7, 7 'first housing part 5 is inserted into the second housing part 6, 6', that the cup-shaped first beam disintegrator portion 17, 17 'of the first Housing parts 5 in the sleeve interior of the second housing part 6, 6 'protrudes. In the figures, it can be seen particularly clearly that an inner sleeve 19, 19 'is provided in the second housing part 6, 6', the outlet end face of which forms the central outlet opening 10, 10 'of the jet regulator housing. This inner sleeve 19 is integrally formed in the insertion unit 1 in the second housing part 6. The outlet end face of the inner sleeve 19, 19 'forming the central outlet opening 10, 10' is here designed as a grid or network structure which is formed by webs 21, 21 'which intersect at intersection nodes and are delimited between outlet openings 20, 20' , The webs 21, 21 'of this lattice structure are arranged here such that the outlet openings: 20, 20' practically form a honeycomb cell-like lattice structure. In the rotational position of the grille parts 5, 6 shown in FIGS. 2 and 4, the individual jets formed in the burster openings 8 are guided against the outer channel wall of the jet channels 9. This flow path is indicated in Figure 2 by the arrow line Sl. In order to guide the individual jets formed in the burster openings 8 against the outer channel wall, at least the inner inner peripheral wall of the burster openings 8 is oriented obliquely outward. Each individual jet emerges from its associated jet channel 9 in the bisector of the opposite channel walls, each individual jet is flattened after hitting the Gehäuseinnenumfangswandung and so forms a closed and practically a circumferential ring wall forming water curtain. In FIG. 15, it can be seen that in the outlet-side partial region of the jet regulator housing, a profiling is provided on the inner peripheral side, which is formed by indentations 22, 23. At the same time, they rejuvenate between two adjacent ones Formations 23 formed integrals 22 in the outlet direction such that the spray jet generated in the rotational position shown in Figure 2 can continue to spread until exiting the jet regulator housing. The indentations and formations 22, 23 form guiding ribs and guide grooves on the inner circumference of the housing, which further promote the spreading of each individual beam, so that a discharge area which widens conically outwards forms the spray jet over the longitudinal axis of the jet - giving direction. The spread of the spray jet formed from the individual rays is further promoted by the fact that the outlet-side partial region of the second housing part 6 has a clear housing cross-section widening in the outlet direction and that a sharp tear-off edge is provided on the inner circumference of this outlet-side partial region.

In the rotational position shown in FIGS. 1 and 3, the water coming from the flow rate regulator 4 is directed radially outwards to the burster openings 8, in order subsequently to be guided as individual jets through the free spaces or longitudinal gaps remaining between the jet channels 9, which in each case in a radially inwardly formed and serving as Umlenkschräge 37 rounding hen, which deflects these individual rays in the direction of the inner sleeve 19. In the inner sleeve 19, an insert part 24 is used on the inflow side, which has a grid or network structure, which is formed of webs crossing at intersection nodes. The rotational position of the housing parts 5, 6 according to Figures 1 and 3 corresponding flow path is shown in Figure 1 by the

Arrows S2 illustrates. Since the burster openings 8 of the jet separator 7 represent cross-sectional constrictions, the individual jets formed in the burster openings 8 experience a Speed increase, which leads to a negative pressure according to the Bernoulli equation on the downstream side of the jet breaker 7. The negative pressure formed on the outflow side of the jet breaker 7 causes ambient air to be sucked into the housing interior of the jet regulator housing via the jet channels 9, which are formed there with the individual jets to form a homogeneous, non-squirting and pearly-soft overall jet. In this case, the mixing space formed between the insert part 24 and the downstream end face of the cup-shaped jet separator subregion 17 is reduced by the cup-shaped design of the jet separator 7 such that a comparatively small mixing chamber is formed, in which no unwanted resonances can occur. The good mixing of the ambient air sucked into the interior of the housing with the water flowing through the jet regulator 2 is additionally facilitated by _: the grid or network structure of the insert 24 arranged on the outflow side of the mixing chamber and into the housing interior of the jet regulator - Housing is used.

It can be seen from a comparison of the rotational positions shown in FIGS. 1 and 3 on the one hand and FIGS. 2 and 4 on the other hand that the flow paths S1 or S2 do not seal: between the two jet types of the jet regulator 2-namely, as an expanding ring wall exiting jet on the one hand and aerated overall jet on the other hand - require.

The flow rate regulator 4 can be used up to a support 25, 25 'in the first housing part 5. Since the intent or filter screen 3, 3 'with the first housing part 5, 5' releasably connected, preferably releasably latched, is the intent or; Filter sieve 3, 3 'nachge in the flow direction switched flow rate regulator 4, 4 'in the interior of the first housing part 5, 5' in the area of the jet breaker 7, 7 'space-saving housed. The flow rate regulator 4, 4 'here has at least one annular gap 26, 26', in each of which an annular throttle body 27, 27 'of elastic material is inserted. The at least one annular gap 26, 26 ^v has on its inside and / or outside circumferential wall a control profiling, between which and the elastic throttle body 27, 27 'a control gap remains, which narrows under the increasing pressure of the inflowing water, the amount of water flowing through per unit of time is adjusted to a defined maximum value.

Also; The insertion unit 1 'shown in FIGS. 16 to 29 can be mounted with the aid of an outlet mouthpiece 28' at the water outlet of a sanitary water outlet fitting not shown here. The outlet nozzle 28 'is formed at least in two parts and has an inflow-side and a downstream-side portion 32', 33 ', which portions 32', 33 'are rotatably connected to each other. On the inflow side portion 32 'of the outlet mouthpiece 28' is an internal or - as here - external thread 34 'is provided, which is mounted in a corresponding external or internal thread on the water outlet. The rotatably interconnected sections 32 ', 33' of the outlet mouthpiece 28 'are each sleeve-shaped, with their sleeve interior pass into each other. In the sleeve inner spaces of the outlet mouthpiece 28 'and its sections 32', 33 'of the jet regulator 2' is used. The jet regulator 2 'can also be switched between two outflow jet images. In order to be able to switch over between two exit jet images, the jet regulator 2 'also has two housing parts 5' which can be rotated relative to one another. 6 '. While the inflow-side first housing part 5 'with the help of the portion 32' is held firmly on the water outlet, the downstream second housing part 6 'with the serving as a handle portion 33' of the outlet nozzle 28 'rotatably connected such that the second housing part 6' relative to first housing part 5 'can be rotated.

On the inner circumference of the housing of the second housing part 6 ', preferably uniformly spaced steel channels 9' are provided in the circumferential direction, which trap the individual jets coming from the disintegrating openings 8 'of the jet disintegrator 7'. The second housing part 6 'is formed here from two separate parts, of which the inner sleeve 19' is inserted into an outer sleeve 42 '. The jets coming from the Zerlegeröffnungen 8 'individual jets are in one, first rotational position of the housing parts 5', 6 'between the inner sleeve 19' and the outer sleeve 42 'of the second housing part 6' continued before they reach the downstream arranged spray nozzles 35 ', which in open the outlet side portion of the jet regulator housing. In the annular space located between the jet channels 9 'and the spray nozzles 35', the jet regulator 2 'has at least one ring insert 36' which has a grid or network structure and which is intended to serve as a flow rectifier which compares the water flowing through it. This grid structure is formed in the ring insert 36 'used here by radial webs, which limit flow holes between them. Since at least the inner portion of the spray nozzles 35 'bounding peripheral walls is directed obliquely outward, the separately from the spray nozzles 35' visible separately emerging individual beams are deflected obliquely outwards, so that a formed from diverging individual jets, annular peripheral outflow jet image is formed. In contrast to the second rotational position of the housing parts 5 ', 6', the individual jets emerging from the breaker openings 8 'are each guided over a deflection slope 37', which projects the individual jets formed in the breaker openings 8 'in this second rotational position in the direction of the central outlet opening 10 'deflect radially inward. In this case, one of the deflecting bevels 37 'is provided between adjacent jet channels 9'. In the deflection bevels 37 'is in each case a rafts or fin-shaped flow divider 44' is provided, which already causes a first division of the inflowing water. By the fin-shaped flow divider 44 ', the radially inwardly deflected at the Umlenkschrägen 37' water is divided into at least two partial streams, wherein the radially inwardly diverted partial streams in each case in turn on the downstream of the jet separator 7 'projecting pins 38' impinge and be there again divided so that a particularly good mixing of the flowing through the jet regulator 1 'water with the Utngebungsluft. The thus mixed with ambient air water can then escape via the central outlet opening 10 'from the jet regulator 2' as a ventilated water jet.

As already described for the insertion unit 1 shown in FIGS. 1 to 15, the water guided via the deflection slopes 37 'in the interior of the jet regulator housing is also mixed with ambient air. Since the burster openings 8 'of the jet breaker 7' represent cross-sectional constrictions, the individual jets formed in the Zerlegeröffnungen 8 'experienced an increase in speed, which leads according to the Bernoulli equation on the downstream side of the jet breaker 7' to a negative pressure. The negative pressure formed on the outflow side of the jet breaker 7 'causes ambient air into the housing interior of the jet regulator housing via the spray nozzles 35' is sucked in there, which are formed there with the individual jets to a homogeneous, non-squirting and pearly-soft overall jet, which flows through the central outlet opening 10 '. The good mixing of the sucked into the housing interior ambient air with the water flowing through the jet controller 2 is further favored by the at the outflow side of the pot bottom of the pot-shaped Strahlzerlegers 7 'in the flow direction protruding pins 38'. In the rotational position shown in FIG. 25, the ambient air sucked in via the spray nozzles 35 'is guided via the air intake ducts of the inflow-side first housing part 5' oriented approximately in the longitudinal extent of the jet regulator 2, wherein pocket-shaped recesses 45 'are formed there on the outflow side of the jet breaker 7'. are located. Looking at the figures 21, 22, 26, 27 and 29 together, it can be seen that the breaker openings 8 'of the jet breaker 7' open into channel-shaped discharge channels which extend from one another in the circumferential direction through these pocket-shaped recesses 45 'on the downstream side of the jet breaker 7' are separated. In the rotational position shown in FIG. 25, in which the water mixed with ambient air flows out of the jet regulator 2 'through the central outlet opening 10', excessive spraying of the water impinging on the deflecting slopes 37 'is avoided, which otherwise exceeds that in this rotational position Air intake ducts serving jet channels 9 'could flow out. In the rotational position shown in FIG. 25, these pocket-shaped recesses 45 'produce a splash guard which prevents a leakage of leakage flows from the spray nozzles 35'. With these pocket-shaped recesses 45 ', not only can material savings be achieved in the manufacture of the housing part 5', but rather these recesses 45 ', which carry on the ambient air, also offer improved water splash protection. In the exemplary embodiments 1, 1 'shown in FIGS. 1 to 29, pin-shaped or web-shaped flow obstacles are provided on the outflow side of the deflecting bevels 37, 37'. In the case of the jet regulator 1 shown in FIGS. 16 to 28, pins 38 'are formed on the outflow side of the pot-shaped jet breaker 7' on the bottom of the pot and form such pin-shaped flow obstacles. The in this rotational position inwardly deflected water is guided by these spaced apart pins 38 'and thereby additionally decelerated. The pins 38 ⁴ taper toward their downstream pin ends and have a rounded pin end. In this case, a central Topfboden- portion 40 'is at the pot bottom of the pot-shaped Strahlzerlegers 7' before, this pot bottom of the Strahlzerlegers 7 'is stepped, at least on its downstream side. Despite this step-shaped design of the pot bottom, the pin ends of the pins 38 'are arranged approximately in one plane. The individual jets coming from the burster openings 8 ', which were guided below the pot base of the pot-shaped Strählzerlegers 7' by means of Umlenkschrägen 37 'through the spaced apart and in Stahlregler longitudinally oriented pins 38' are then fed to the central outlet opening 10 ', which forms the escaping water into a homogeneous, non-splashing and pearly soft outflow jet pattern.

In FIGS. 16 and 17 it can be seen that the first housing part of the jet regulator is inserted into the inflow-side end opening of the first section 32 'of the outlet mouthpiece 28' until its peripheral peripheral annular flange 29 'protrudes: on an annular shoulder 30' in the interior of the sleeve first portion 32 'rests. The first housing part 5 'is by a sealing ring 41 'embraced, which seals a between the outer periphery of the first housing part 5' and the downstream end second section 6 'eventually remaining annular gap. The outer sleeve of the second housing part 6 'is latched in the downstream end second portion 33', wherein the outer sleeve 42 'at the same time the inner sleeve 19' between itself and the first portion 32 'holds. The jet splitter 7 'has on its pot bottom inside a central support pin 43', which supports the flow rate regulator 4 'with its end oriented towards the flow direction.
