Description

The invention relates to a jet regulator with a ring-shaped or sleeve-shaped jet regulator housing, in which a, the inflowing water is provided in a plurality of individual beams splitting jet splitter, and provided with a provided on the outlet end side of the jet regulator housing, manually deformable form-elastic plastic coating, which is cup-shaped and seals with a raised peripheral wall of its pot shape on the housing inner circumference of the jet regulator housing.

From the DE 20 2010 002 325 U1 already a jet regulator with a sleeve-shaped jet regulator housing is already known. In the jet regulator housing of the previously known jet regulator, a jet splitter is provided, which has to divide the incoming water into a plurality of individual jets. The jet splitter has a central cam-shaped depression which has at its peripheral wall circumferentially spaced flow openings. At the outlet end face of the jet regulator housing a manually deformable form-elastic plastic coating is provided, which is designed cup-shaped. This cup-shaped Plastic covering has a plurality of outlet openings, which are delimited by teat-shaped and outlet-side protruding projections of the plastic covering. Here, the soft elastic plastic covering is stiffened by a perforated disc, which forms the outlet end face of the jet regulator housing and the holes are penetrated by the teat-shaped projections of the plastic coating.

Since the peripheral edge of the pot-shaped plastic covering should seal against the housing inner circumference of the jet regulator housing, this peripheral edge is inclined with its inflow-side end edge against the housing inner circumference. The mere inclination of the inflow-side end edge of the plastic covering, however, can not be sufficient, in particular at high water pressures, to preclude leakage currents between the plastic lining on the one hand and the inner housing circumference of the jet regulator housing on the other.

From the DE 198 52 411 A1 already a jet regulator is known, which can be mounted on a sanitary outlet fitting. The previously known jet regulator has a jet regulator housing, which is designed as a sleeve-shaped molded body, on the outlet side of which a soft or form-elastic plastic material is injection-molded. The existing of soft or form-elastic plastic material component of the jet regulator housing forms a soft and / or water-repellent surface, with a lime formation should be avoided. By slight manual deformations of the superficially molded soft or elastic plastic material adhering calcifications should be easy to remove. Care must be taken in the selection of materials that the soft or elastic plastic material on the other hand hard or rigid plastic material of Sprinkle the jet regulator housing, the production of the previously known jet regulator may require a considerable additional effort.

From the FIGS. 3 to 5 the DE 198 52 411 A1 One already knows a jet regulator with a sleeve-shaped jet regulator housing, the outlet end face is formed as a usable in the jet regulator Auslaufscheibe, which carries a flat grid structure with flow openings. The jet regulator housing of the previously known jet regulator is formed from two housing halves adjoining one another in a longitudinal center plane, between which the flat grid structure can be inserted before the housing halves are folded together. This lattice structure has a very thin coating of a soft and / or water-repellent plastic material which can be applied by dip coating or by spraying onto the formed as a plastic injection molded part grid structure. By the water-repellent plastic layer of lime formation at the outlet end of the jet regulator housing should be largely counteracted. Due to the soft design of this plastic layer, a cleaning of the outlet end face is to be facilitated, since by slight manual surface deformation any adhering calcifications are easily removable. The formed as a plastic injection molded part grid structure of DE 198 52 411 A1 The previously known jet regulator is dimensionally stable such that this lattice structure can be inserted into the housing interior only before the housing halves of the longitudinally split jet regulator housing are folded together. Since the soft coating is applied by dip coating or by spraying, and since the soft coating is correspondingly thin, the plastic injection-molded part of the lattice structure must at the same time be sufficiently yielding to achieve surface deformation, can replace the adhering calcifications. The lattice structure of the previously known jet regulator is therefore designed so flat that the wall sections delimiting the flow openings of the lattice structure can not simultaneously act as flow guide walls.

From the DE 103 13 501 A1 One already knows a jet regulator whose jet regulator housing is deformable, at least in the region of the liquid outlet, from an undeformed functional layer into a shape-changed cleaning layer. The achievable by manual pressurization deformability of the housing is greater than the Bruchdehnbarkeit of adhering to the housing deposits and dimensioned so that such deposits can be released from the housing. As in the case of DE 103 13 501 A1 previously known jet regulator the jet regulator housing, if appropriate, should have such a defined deformability only in a partially limited subregion, the production of the previously known jet regulator and its complex designed jet regulator housing is associated with considerable effort.

From the DE 10 2010 012 326 Known already a jet regulator of the type mentioned with a jet regulator housing, at the outlet end face an insertable into the jet regulator housing Auslaufscheibe is held, which has a perforated, grid or network structure with flow openings, wherein the spout carries a manually deformable form-elastic plastic coating. In order to produce such a jet regulator with comparatively little effort from a variety of materials, the discharge disk is designed as a multi-component injection molded part whose base or molded body is made of hard or dimensionally stable plastic material, wherein the basic or molded body with a component from the other soft or form-elastic Plastic material is encapsulated, and wherein the flow openings of the perforated, grid and / or network structure are bounded by flow guide walls. Despite the separate design, the production of the multi-component injection-molded part serving as discharge disc requires considerable effort. In order to be able to produce such a multi-component injection molded part, in particular from different materials, complex injection molding tools are required, in which the various materials can be processed in accordance with the processing conditions required for this purpose. The provision of complex injection molding tools and the different manufacturing steps adapted to the different materials require considerable expense.

There is therefore in particular the task of creating a structurally simple and functionally reliable jet regulator of the type mentioned, which can be produced with the least possible effort.

The achievement of this object is in the jet regulator of the type mentioned in particular that at the outlet end face an insertable into the jet regulator housing is held disc having a perforated, grid and / or network structure with flow openings, that the outlet disc to manually deformable carries formelastic plastic covering, that the plastic covering is releasably held on the outlet disk, that the outlet disk and the plastic covering are mutually pivotally supported in the jet regulator housing that seals the plastic covering with its raised peripheral wall between the outer periphery of the outlet disk and the housing inner circumference of the jet regulator housing and the downstream on the Jet splitter a central cam is formed, which is supported during pivoting of the discharge disc on this or on an inflow on the outlet disc molded central cam.

The jet regulator according to the invention has a jet regulator housing which is designed in the form of a ring or sleeve. At the outlet end face of the jet regulator housing a discharge disc is held, which is insertable into the jet regulator housing. This spout disc, which has a perforated, grid and / or mesh structure with flow openings, also carries a manually deformable form-elastic plastic covering, which can be freed by manual pressurization and deformation of calcium deposits. Since the plastic lining is releasably held on the outlet disk, the plastic lining and the outlet disk can be made separately from each other. Since the discharge disk and the plastic covering which is detachably held thereon are produced separately from one another, comparatively simple injection molding tools can therefore be used, and the production steps can be carried out irrespective of different material properties. In this case, the plastic covering is fixed as a separately manufactured component on the outlet disk. The plastic covering is designed cup-shaped, such that the plastic covering with a raised peripheral wall of its cup shape seals between the outer periphery of the outlet disk and the housing inner circumference of the jet regulator housing. In this way, unwanted leakage currents in the region between the outlet disk and the housing inner circumference of the jet regulator housing are avoided, which could otherwise adversely affect the jet pattern of the jet regulator according to the invention. Since the plastic covering with a raised peripheral wall of its pot shape between the outer periphery of the outlet disk and the housing inner circumference of the jet regulator housing seals, and since thus the plastic lining bearing Auslaufscheibe is inserted into the jet regulator housing, a modular system is also possible, in which the plastic lining bearing Auslaufscheibe is interchangeable with another Auslaufscheibe with or without plastic coating, for example, the material properties and / or If necessary, it is possible to change the flow characteristic of the jet regulator according to the invention. In order to allow an alignment of the water jet emerging from the jet regulator, the outlet disk with the plastic covering carried thereby is pivotably held in the jet regulator housing. By pivoting the existing outflow disc and plastic coating unit in the jet regulator housing, the outflow of the outflowing water jet can be changed if necessary.

In order to be able to shape the water flowing through well in the jet regulator according to the invention, it is provided that the jet regulator has one, the inflowing water in a plurality of individual beams dividing beam splitter. At this jet splitter, a central cam is formed downstream. This, provided on the jet splitter cam is supported during pivoting of the outlet disk on this or on an inflow on the outlet disc integrally formed central cam from such that a pivoting movement of the unit formed from the outlet disk and plastic covering is facilitated.

In order to securely and firmly and yet be able to fix a separately produced from the spout disc plastic pad on the spout disc, yet with little effort, it is advantageous if the plastic pad is held positively against the spout disc.

In this case, a particularly advantageous embodiment according to the invention, in which the plastic covering completely seals between the outlet disk and the housing inner circumference of the jet regulator housing, provides that the plastic lining with the free edge region of its peripheral wall facing away from the bottom of the pot is held in a form-fitting manner on the outlet disk.

The separately produced plastic lining of the jet regulator according to the invention can be clamped in a simple manner between the outlet disk and the housing inner circumference of the jet regulator housing and set. However, in order not to impair the mobility of these components of the jet regulator according to the invention and to ensure the proper functioning of the jet regulator, it may be expedient if the free edge region of the circumferential wall facing away from the bottom of the pot is angled inwards in such an area that this edge region encloses the inflow-side peripheral end edge Outlet disk engages behind. In this embodiment, the plastic covering with the outlet disc forms a largely immovable unit, although the plastic coating is kept only releasably on the outlet disk.

In addition or instead, however, the plastic covering may also have on the inner peripheral side at least one preferably circumferential holding recess or recess on the free edge region of its circumferential wall facing away from the bottom of the pot, which cooperates with a holding recess or recess on the outer circumference of the outlet disk.

In this case, an advantageous embodiment according to the invention provides that the plastic covering on the inside and on the outlet disk are provided on the outside each pairwise corresponding positioning aids.

In order to be able to connect the outlet disk to the plastic covering and / or to easily produce the relative position between the plastic lining and the outlet disk during assembly, it is advantageous if the outlet disk has at least one connecting pin or connection opening on its downstream end face. which cooperates with a connection opening or a connecting pin on the outlet disk facing end face of the plastic covering.

A preferred development according to the invention provides that the plastic covering has on its inflow-side outer circumference at least one circumferential sealing lip or sealing nose, which seals with / on the inner circumference of the jet regulator housing. Such a plastic covering, which has at least one circumferential sealing lip or sealing nose on its outer circumference, can seal the region between the outlet disk on the one hand and the inner housing circumference of the jet regulator housing on the other hand particularly well.

A structurally simple and particularly advantageous embodiment according to the invention provides that the outlet disc and / or the plastic covering which surrounds it is designed in the manner of a spherical segment on its outer circumference, and the swivel disk thus formed is pivotably mounted in a partial region designed as a socket on the inner circumference of the housing of the jet regulator housing. In this embodiment, for example, the unit formed from the outlet disk and the plastic coating form a ball-joint-like swash plate which is pivotally mounted in the socket provided in the housing interior of the jet regulator housing.

In order for the unit formed from the outlet disk and the plastic covering to be held firmly in the housing interior of the jet regulator housing even at high water pressures, a preferred embodiment according to the invention provides that the outlet disk can be inserted through an inflow-side insertion opening up to the partial area designed as a socket in the interior of the housing Radiation controller housing is used.

It is advantageous if the outlet disk and the plastic lining have flow openings which merge into one another. The flow openings provided in the outlet disk and the plastic covering and merging into one another are thus delimited by guide walls which align the individual jets formed in the flow openings in the direction of the beam angle defined by the relative position of the outlet disk.

In order to be able to form a homogeneous overall jet with the aid of the jet regulator according to the invention, it is advantageous if the flow openings of the outlet disk and those of the plastic lining are arranged on preferably coaxial hole circles.

In this case, a preferred embodiment according to the invention that arranged on an outer circle of holes Flow openings are provided in a circumferential annular wall of the plastic covering.

In order, if necessary, to be able to generate a spray jet with the aid of the jet regulator according to the invention, which is formed from a plurality of individual jets aligned in the same direction, it is advantageous if the throughflow openings provided in the plastic lining preferably conically constrict at least over a partial region of their longitudinal extension in the direction of flow ,

Possible limescale deposits are particularly easy to solve if a downstream portion of at least one flow opening and preferably the arranged at least on the inner hole circles flow openings in a projecting over the plastic covering teat or a projection is provided.

In addition or instead, it may be advantageous if the cam provided on the jet splitter is supported on the cam of this runner disk during pivoting of the outlet disk.

In order to prevent excessive pivoting of the outlet disk and to always ensure proper functioning of the designed as a pivoting jet regulator jet regulator, it is advantageous if a component inserted upstream of the outlet disk in the jet regulator housing is formed a pivot stop for the designed as a swash plate Auslaufscheibe.

A preferred embodiment according to the invention, which ensures a firm hold of the constituent elements forming the jet regulator according to the invention, provides that the Beam splitter is designed as an inflow-side pot bottom of a pot-shaped insert part, which cup-shaped insert part is inserted into the jet regulator housing.

The installation of the jet regulator according to the invention is facilitated if the insert in the jet regulator housing and releasably is held in particular frictionally and / or positively.

In particular, in the case of strongly fluctuating water pressures, it can be advantageous if the flow regulator is preceded by a flow rate regulator on the inflow side, and if the flow rate regulator is preferably detachably connected to the jet divider and held in particular latchable.

FIG. 11:

off the jet regulator FIG. 10 in a detail longitudinal section in the area between the outlet disc, plastic lining and jet regulator housing.

In the FIGS. 1 to 11 is a jet regulator in different versions 1, 100 and 101 shown. The jet regulator 1, 100, 101 is monierbar at the water outlet of a sanitary outlet fitting, not shown here, to form a homogeneous and non-spattering, possibly also pearly soft water jet. The jet regulator embodiments 1, 100, 101 shown here are designed as spray jet regulators, in which the outgoing water jet is formed from a plurality of individual jets issuing approximately axially parallel to each other.

The jet regulator 1, 100, 101 has an annular or sleeve-shaped jet regulator housing 2, at the outlet end face of which a run-out disk 3 which can be inserted into the jet regulator housing 2 is held. This spout 3 carries a manually erfombaren form-elastic plastic covering 4, which can be freed by manual pressurization and deformation of calcium deposits. In the case of the jet regulator 1, 100, 101, this plastic covering 4, which is made of a form-elastic plastic, is manufactured separately from the outlet disc 3, which is made of a harder material and, in particular, harder plastic material, and then detachably held on the outlet disc 3. Since the outlet disk 3 and the plastic covering 4 detachably held thereon are produced separately from one another, this can be done comparatively Simple injection molding tools are used and the manufacturing steps are feasible regardless of different material properties. Since the plastic covering 4 is detachably held on the outlet disk 3, a modular system is also possible in which the one plastic covering 4 is exchangeable with another plastic covering, in order, for example, to be able to change the material properties and / or the flow characteristic of the jet regulator if necessary. In this case, the plastic covering 4 is designed cup-shaped in such a way that the plastic covering 4 with a raised peripheral wall 16 of its cup shape between the outer periphery of the outlet disk 3 and the housing inner circumference of the jet regulator housing 2 seals.

The outlet disk 3 and the plastic covering 4 have flow openings 5, 7 merging into one another, each forming a hole, grid and / or net structure and here a hole structure.

In Fig. 4 It can be seen that the outlet disk 3 is held pivotably in the jet regulator housing 2 with the plastic covering 4 provided thereon. The outlet disk 3 and here also the plastic covering 4 together form a spherical segment-shaped swivel disk on its outer circumference, which is mounted pivotably in a partial region configured as a joint socket 6 on the housing inner circumference of the jet regulator housing 2.

In the FIGS. 1, 4 . 8th and 10 It can be seen that the outlet disk 3 and the plastic covering 4 held thereon pass through an inflow-side insertion opening of the jet regulator housing 2 as far as the partial region configured as a joint socket 6 into the interior of the housing Radiation controller housing 2 can be used. In the FIGS. 1, 4 . 8th and 10 can also be seen that the flow openings 5, 7 of the outlet disk 3 and the plastic lining 4 are arranged on concentric hole circles. At least on an outer hole circle and here arranged on all bolt holes flow openings 7 in the plastic covering 4 are provided in a circumferential annular wall 8 of the plastic covering 4. It is also possible that an outflow-side portion of at least the arranged on the inner hole circles flow openings 7 each provided in a over the plastic covering 4 protruding teat or a projection.

In the longitudinal sections according to the FIGS. 1, 4 . 8th and 10 It can be seen that the flow openings 7 provided in the plastic covering 4 conically constrict in the flow direction at least over a partial region of their longitudinal extent.

In the jet regulator housing 2 of the jet regulator 1, 100, 101 is a cup-shaped insert part 11 can be used, the inflow-side pot bottom is designed as a beam splitter 10. This jet separator 10 has a central and here cam-shaped depression 12, which has on its peripheral wall 13 in the circumferential direction preferably equally spaced flow openings 14. The outflow-side peripheral end edge of the insert part 11 arranged on the inflow side upstream of the outlet disk 4 is designed as a pivot stop for the unit which serves as a swivel disk and is formed from the outlet disk 3 and the plastic covering 4.

Around the central recess 12 of the jet breaker 10 around openings 12 are provided at a radial distance from the recess 12, which in a coaxial circle of holes around the recess 12 are arranged around. The water flowing into the jet regulator housing 2 is deflected in the depression 12 and passed through the flow openings 14 into the housing interior of the jet regulator housing 2. The individual jets formed in the flow openings 14 are deflected and the turbulence caused by these individual jets form a mixing zone in the housing interior of the jet regulator housing 2, which favors the production of a soft and homogeneous water jet.

The insert part 11 is detachably and in particular positively held in the jet regulator housing 2. On the pot-shaped insertion part 12, a locking flange 18 is circumferentially provided, which engages in a locking groove 19 on the housing inner circumference of the jet regulator housing 2.

In the longitudinal sections according to the FIGS. 1, 4 . 8th and 10 it can be seen that the depression 12 on the downstream side of the jet breaker 10 forms a central cam. This downstream of the jet splitter 10 provided cam is acted upon by a cam or pin 17 which projects on the inflow side of the outlet disk 3. Upon pivoting of the outlet disk 3 and the plastic lining 4 held thereon, the cams formed on the jet separator 10, on the one hand, and on the outlet disk 3, on the other hand, abut each other. In FIG. 4 It can be seen that the insertion part 11 inserted in front of the outlet disk 4 forms a pivot stop for the unit formed as a swashplate of the outlet disk 3 and the plastic covering 4.

In the single part illustration according to figures it can be seen that the outlet disk 3 and the plastic covering 4 of the Jet regulator versions 1, 100, 101 are held against rotation against each other. For this purpose, the one component 3 or 4, at least one longitudinal groove or the like securing groove 23 is provided here, into which a locking projection 24 engages the respective other component 4 or 3.

From a comparison of FIGS. 1 to 4 It is clear that the bottom of the pot facing away from the free edge region 20 of the provided on the plastic covering 4 peripheral wall is angled in the jet regulator 1 inwardly such that this edge region 20 engages behind the inflow-side peripheral end edge of the outlet disk 3. In contrast, the outlet disk 3 is used in the jet regulator 100 only in the plastic covering 4 and is securely held between the jet regulator housing 2 and the insert 11 in the housing interior of the jet regulator housing. In order to regulate the flow rate pressure-independent to a maximum value, the jet regulators 1, 100, 101, a flow rate controller 21 is connected upstream. This flow regulator 21 is on the inflow side of the jet separator 10 releasably held and in particular releasably latched. On the flow regulator 21, a header or filter screen 22 is placed, which has to retain dirt particles.

While in the jet regulator 100 according to the 8 and 9 the outlet disc 3 is merely inserted into the pot-shaped plastic covering 4, these components 3, 4 of the jet regulator 1, 100 are positively connected to each other. For this purpose, the plastic covering 4 is held with the free edge region of its peripheral wall facing away from the bottom of the pot form fit to the outlet disk 3. In the Fig. 1 to 4 can be seen that the bottom of the pot facing away from the free edge region 20 of the peripheral wall can be angled inwardly such that this edge region 20 engages behind the inflow-side circumferential end edge of the outlet disk 3. Additionally (cf. Fig. 1 to 4 ) or instead (cf. 10, 11 ), the plastic covering 4 on the inner side facing away from the bottom of the pot free edge region of its peripheral wall at least a preferably circumferential Halteeinformung and / or - as here - Halteausformung 28, which cooperates with a Halteausformung or Halteeinformung 29 on the outer circumference of the outlet disk 3.

So that the outlet disk 3 and the plastic covering 4 have flow openings 5, 7 which merge into one another, a fixed relative position between these components 3, 4 must be ensured. In order to be able to ensure the desired relative position between the plastic covering 4 and the outlet disk 3, it is expedient if, on the inside, and on the outlet disk 3 on the outside, in each case paired with corresponding positioning aids are provided on the outside. So is in the item view according to Fig. 7 recognizable that the outlet disk 3 and the plastic covering 4 are held against rotation against each other. For this purpose, at least one longitudinal groove or similar positioning groove 23 is provided on the one component 3 or 4, in which a positioning projection 24 engages the respective other component 4 or 3. Additionally or instead, it is possible that the outlet disk 3 on its downstream end face at least one connecting pin or - as here - a connection opening 25, which / which cooperates with a connection opening or a connecting pin 26 on the outlet disk 3 facing end side of the plastic covering 4. In the jet regulator 101 according to the 10 and 11 is provided in the outlet disk 3 connection opening 25 formed as a continuous connection opening, which passes through the plastic covering 4 against the flow direction projecting connecting pin 26.

In Fig. 3 is indicated that the plastic covering 4 may have on its inflow-side outer circumference at least one circumferential sealing lip or sealing nose 27, which seals on the inner circumference of the jet regulator housing 2.

From a general view of the Fig. 6 and 7 It is clear that the flow openings 5, 7 of the outlet disk 3 and the plastic lining 4 are arranged on concentric hole circles. It is in Fig. 6 It can be seen that the throughflow openings 7 of the plastic covering 4 arranged on at least one, preferably on an outer and here on all of the perforated circles, are each provided in a peripheral annular wall 8 of this plastic covering 4. It is also possible, however, that a downstream portion of at least one flow opening 7 and preferably arranged on the inner hole circles flow openings 7 is provided in a projecting over the plastic covering 4 teat or a projection.

The positioning of plastic covering 4 and outlet disc 3 by the pairwise cooperating connection openings 25 and connecting pins 26 is particularly advantageous in the production of the jet regulator, as a quick installation is possible because it is immediately apparent that the connecting pin 26 of the plastic covering 4 may not be in position the connection opening 25 of the outlet disk 3 is introduced. It can not come to a leak in the area of these positioning aids 25, 26, since the the plastic covering 4 protruding connecting pin 26 is made of elastic material, so that an additional anchoring is achieved by mushroom-like deformation of the connecting pin 26 at its free end of the pin after insertion of the connecting pin 26 in the connection opening 25. In any case, leakage in this area would only lead to leakage water leaving one of the flow openings 7 downstream.
