DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(14) FIGS. 1 to 11 illustrate a jet regulator in various embodiments 1, 100 and 101. The jet regulator 1, 100, 101 is fittable on the water outlet of a sanitary outlet fitting (not shown specifically) in order to form a homogeneous and non-spraying, optionally also sparkling and soft water jet. The jet regulator embodiments 1, 100, 101 illustrated here are configured as a spray jet regulator in which the emerging water jet is formed from a plurality of individual jets emerging approximately axially parallel to one another.

(15) The jet regulator 1, 100, 101 has a ring-shaped or sleeve-shaped jet regulator housing 2, on the outlet end side of which an outlet disk 3 insertable into the jet regulator housing 2 is held. Said outlet disk 3 bears a manually deformable, dimensionally elastic plastic lining 4 which can be freed from limescale deposits by manual pressurization and deformation. In the case of the jet regulator 1, 100, 101, said plastic lining 4 produced from dimensionally elastic plastic is manufactured separately from the outlet disk 3, which is composed, in contrast, of harder material and in particular harder plastic material, and is subsequently held releasably on the outlet disk 3. Since the outlet disk 3 and the plastic lining 4 held releasably thereon are produced separately from each other, comparatively simple injection molding dies can be used for this purpose, and the production steps can be carried out regardless of different material properties. Since the plastic lining 4 is held releasably on the outlet disk 3, a modular system is also possible, in which the one plastic lining 4 is replaceable by another plastic lining in order to be able to change, for example, the material properties and/or the throughflow characteristics of the jet regulator when required. The plastic lining 4 here is of cup-shaped design, specifically in such a manner that the plastic lining 4, by means of a raised circumferential wall 16 of the cup shape thereof, provides a seal between the outer circumference of the outlet disk 3 and the housing inner circumference of the jet regulator housing 2.

(16) The outlet disk 3 and the plastic lining 4 have throughflow openings 5, 7 which merge into each other and in each case form a perforated, grate and/or mesh structure and here a perforated structure.

(17) It can be seen in FIG. 4 that the outlet disk 3 is held pivotably together with the plastic lining 4, which is provided thereon, in the jet regulator housing 2. The outlet disk 3 and also the plastic lining 4 here together form a pivoting disk which is in the shape of a spherical segment on the outer circumference thereof and is mounted pivotably in a partial region, which is configured as a joint socket 6, on the housing inner circumference of the jet regulator housing 2.

(18) It can be seen in FIGS. 1, 4, 8 and 10 that the outlet disk 3 and the plastic lining 4 held thereon are insertable into the housing interior of the jet regulator housing 2 through an inflow-side insertion opening in the jet regulator housing 2 as far as the partial region configured as a joint socket 6. It can also be seen in FIGS. 1, 4, 8 and 10 that the throughflow openings 5, 7 of the outlet disk 3 and of the plastic lining 4 are arranged on concentric hole circles. At least the throughflow openings 7 arranged on an outer hole circle, and here the throughflow openings 7 arranged on all of the hole circles, in the plastic lining 4 are provided in an encircling ring wall 7 of the plastic lining 4. It is also possible that an outflow-side partial region at least of the throughflow openings 7 arranged on the inner hole circles is provided in each case in a teat projecting over the plastic lining 4 or in a projection.

(19) It can be seen in the longitudinal sections according to FIGS. 1, 4, 8 and 10 that the throughflow openings 7 provided in the plastic lining 4 taper conically at least over a partial region of the longitudinal extent thereof in the flow direction.

(20) A cup-shaped insertion part 11, the inflow-side cup base of which is configured as a jet splitter 10, is insertable into the jet regulator housing 2 of the jet regulator 1, 100, 101. Said jet splitter 10 has a central and here cam-shaped hollow 12, the circumferential wall 13 of which has throughflow openings 14 which are preferably spaced apart from one another uniformly in the circumferential direction. The outflow-side circumferential end edge of the insertion part 11 arranged upstream of the outlet disk 4 on the inflow side is designed as a pivoting stop for the unit which serves as a pivoting disk and is formed from outlet disk 3 and plastic lining 4.

(21) Openings 15 are provided around the central hollow 12 of the jet splitter 10, at a radial distance from the hollow 12, said openings being arranged in a coaxial hole circle around the hollow 12. The water flowing into the jet regulator housing 2 is deflected in the hollow 12 and is conducted further through the throughflow openings 14 into the housing interior of the jet regulator housing 2. In the process, the individual jets formed in the throughflow openings 14 are deflected and, in the housing interior of the jet regulator housing 2, the resulting swirling of said individual jets forms a mixing zone which promotes the production of a soft and homogeneous water jet.

(22) The insertion part 11 is held releasably and in particular in a form-fitting manner in the jet regulator housing 2. For this purpose, a latching flange 18 is provided on the circumferential side of the cup-shaped insertion part 12, said latching flange engaging in a latching groove 19 on the housing interior circumference of the jet regulator housing 2.

(23) It can be seen in the longitudinal sections according to FIGS. 1, 4, 8 and 10 that the hollow 12 forms a central cam on the outflow side of the jet splitter 10. Said cam which is provided on the outflow side of the jet splitter 10 is acted upon by a cam or pin 17 which projects on the inflow side of the outlet disk 3. When the outlet disk 3 and the plastic lining 4 held thereon are pivoted, the cams integrally formed on the jet splitter 10, on the one hand, and on the outlet disk 3, on the other hand, are supported on each other. It can seen in FIG. 4 that the insertion part 11 which is inserted upstream of the outlet disk 4 forms a pivoting stop for the unit consisting of outlet disk 3 and plastic lining 4, which unit is configured as a pivoting disk.

(24) In the illustration of individual parts according to the figures, it can be seen that the outlet disk 3 and the plastic lining 4 of the jet regulator embodiments 1, 100, 101 are held on one another in a manner secure against rotation. For this purpose, at least one longitudinal flute or similar securing groove 23 is provided the one component 3 or 4, in which a securing projection 24 on the other component 4 or 3 in each case engages.

(25) From a comparison of FIGS. 1 to 4, it becomes clear that, in the case of the jet regulator 1, the free edge region 20 of the circumferential wall provided on the plastic lining 4, which free edge region faces away from the cup base, is angled inwards in such a manner that said edge region 20 engages behind the inflow-side circumferential end edge of the outlet disk 3. By contrast, in the case of the jet regulator 100, the outlet disk 3 is merely inserted into the plastic lining 4 and is held securely between the jet regulator housing 2 and the insertion part 11 in the housing interior of the jet regulator housing. In order to adjust the throughflow capacity to a maximum value independently of the pressure, a throughflow quantity regulator 21 is connected upstream of the jet regulators 1, 100, 101. Said throughflow quantity regulator 21 is held releasably, and in particular is latchable releasably, on the jet splitter 10 on the inflow side. An ancillary or filter screen 22 which has to retain dirt particles is placed onto the throughflow quantity regulator 21.

(26) While, in the case of the jet regulator 100 according to FIGS. 8 and 9, the outlet disk 3 is merely placed into the cup-shaped plastic lining 4, said parts 3, 4 of the jet regulator 1, 100 are connected to each other in a form-fitting manner. For this purpose, the plastic lining 4 is held by the free edge region of the circumferential wall thereof, which edge region faces away from the cup base, in a form-fitting manner on the outlet disk 3. It can be seen in FIGS. 1 to 4 that the free edge region 20 of the circumferential wall, which edge region faces away from the cup base, can be angled inward in such a manner that said edge region 20 engages behind the inflow-side circumferential end edge of the outlet disk 3. In addition (cf. FIGS. 1 to 4) or instead (cf. FIGS. 10 and 11), the plastic lining 4 can have, on the free edge region of the circumferential wall thereof, which edge region faces away from the cup base, on the inner circumferential side at least one preferably encircling recessed retaining molding and/or, as here, projecting retaining molding 28, which interacts with a projecting retaining molding or recessed retaining molding 29 on the outer circumference of the outlet disk 3.

(27) In order that the outlet disk 3 and the plastic lining 4 have throughflow openings 5, 7 merging into each other, a defined relative position between said parts 3, 4 should be ensured. In order to be able to ensure the desired relative position between plastic lining 4 and outlet disk 3, it is expedient if positioning aids corresponding with each other in each case in pairs are provided on the inner side of the plastic lining 4 and on the outer side of the outlet disk 3. It can thus be seen in the illustration of the individual parts according to FIG. 7 that the outlet disk 3 and the plastic lining 4 are held on each other in a manner secured against rotation. 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 on the other component 4 or 3 in each case engages. In addition or instead, it is possible that the outlet disk 3, on the outflow-side end side thereof, has at least one connecting pin or, as here, a connecting opening 25, which connecting pin/connecting opening interacts with a connecting opening or a connecting pin 26 on that end side of the plastic lining 4 which faces the outlet disk 3. In the case of the jet regulator 101 according to FIGS. 10 and 11, the connecting opening 25 provided in the outlet disk 3 is designed as a continuous connecting opening through which the connecting pin 26 projecting on the plastic lining 4 counter to the flow direction passes.

(28) It is indicated in FIG. 3 that the plastic lining 4, on the inflow-side outer circumference thereof, has at least one encircling sealing lip or sealing lug 27 which seals against the inner circumference of the jet regulator housing 2.

(29) From an overall view of FIGS. 6 and 7, it becomes clear that the throughflow openings 5, 7 of the outlet disk 3 and of the plastic lining 4 are arranged on concentric hole circles. It can be seen in FIG. 6 that the throughflow openings 7 of the plastic lining 4, which throughflow openings are arranged on at least one hole circle, preferably on an outer hole circle and here on all of the hole circles, are in each case provided in an encircling ring wall 8 of said plastic lining 4. However, it is also possible for an outflow-side partial region of at least one throughflow opening 7 and preferably of the throughflow openings 7 arranged on the inner hole circles to be provided in a teat projecting over the plastic lining 4, or in a projection.

(30) The position of plastic lining 4 and outlet disk 3 by means of the connecting openings 25 and connecting pins 26 interacting in pairs is advantageous in particular in the production of the jet regulator since rapid assembly is possible because it can immediately be seen that the connecting pin 26 of the plastic lining 4 is possibly not introduced into the connecting opening 25 of the outlet disk 3 in a suitable position. Leakage cannot occur in the region of said positioning aids 25, 26 since the connecting pin 26 projecting on the plastic lining 4 is composed of elastic material, and therefore an additional anchoring is achieved by mushroom-head-like deformation of the connecting pin 26 at the free pin end thereof after the connecting pin 26 is introduced into the connecting opening 25. In any case, leakage in this region would only lead to the leakage water emerging on the outflow side from one of the throughflow openings 7.
