Definitions
- the invention relates to jet regulators that are used, for example, on sanitary fittings.
- Such jet regulators can form two channels that are arranged inside one another and are separate from one another, with an outer channel of the two channels being assigned a splitter unit, through which a water guide of an inner channel of the two channels is inserted.
- jet regulators are already known from practice. They can be used, for example, on sanitary fittings that themselves have two different water channels, for example one for cold water and a second for warm, hot or boiling water.
- the object of the invention is to provide aerator of the type mentioned, which are characterized by a simple structure and associated simple assembly and handling.
- a jet regulator of the type mentioned which has the means and features of the first independent claim directed to such a jet regulator.
- the water supply of the inner channel be locked in the separating unit of the outer channel and thus be fixed in two axial directions.
- the decomposition unit of the outer channel has a double function:
- the separating unit ensures that the water flowing through the outer channel is broken up and, if necessary, mixed with air, and on the other hand, the separating unit acts as a fastening means, which keeps the water flow of the inner channel of the two channels in two axial directions relative to the other elements of the aerator fixed.
- the water guide of the inner channel can be a water guide sleeve. Furthermore, it is possible for the water guide to have a peripheral locking groove in which the separating unit is arranged when the water guide is in the locked position of use.
- the latching groove can define a relative position of the water guide to the splitter unit and also bring about a structurally simple and at the same time reliable axial fixation of the water guide on the splitter unit in two axial directions.
- the locking groove can be delimited axially by two shoulders of the water guide.
- the separating unit can be arranged between the two shoulders of the water guide and within the locking groove.
- one of the two shoulders of the water guide, in particular a downstream shoulder of the water guide has a smaller radial extent than the other shoulder of the water guide, by which the locking groove of the water guide can be limited.
- the shoulder of the water guide with a smaller radial extent can be assigned a, preferably downstream, starting bevel, for example in the form of a starting cone, via which the splitter unit can be inserted into the locking groove of the water guide.
- an aerator of the type mentioned is also proposed, which has the means and features of the second, independent, on such an aerator directed claim has.
- a jet regulator with a splitter unit and an attachment screen is also proposed, which is fastened to the splitter unit with an anchoring element that grips behind the splitter unit on the outflow side. With the aid of the anchoring element, the attachment screen can be fastened to the splitter unit. This can simplify the design of the aerator and its assembly and make it more robust.
- jet regulator it is provided that it has the features of both independent claims, each directed to a jet regulator.
- the anchoring element is, for example, the previously mentioned water guide of the jet regulator.
- the water guide may be a water guide for the aforementioned internal channel.
- the anchoring element not only assumes the function of attaching the attachment screen to the splitter unit, but also as a water guide.
- the anchoring element can have a shoulder which grips behind the splitter unit on the outflow side. In the position of use, the separating unit can lie against the preferably downstream shoulder of the anchoring element and provide a connection between the anchoring element and the separating unit, which ultimately also fixes the attachment screen to the separating unit.
- the anchoring element passes through the splitter unit and/or the attachment screen.
- the dismantling unit and/or the attachment screen can each have a, preferably central, opening through which the anchoring element, in particular the water supply, in Position of use is pushed through in order to attach the attachment sieve to the decomposition unit.
- the splitter unit has a shoulder on the inflow side.
- the attachment screen can lie against this shoulder on the inflow side. Due to the shoulder of the separating unit, the attachment screen can then be fixed axially in its position on the outflow side relative to the separating unit and the anchoring element, in particular the water supply of an inner channel, for example the inner channel already mentioned.
- the anchoring element has a stop, in particular on the inflow side.
- the attachment screen can rest against this stop and be axially secured and fixed in position on the inflow side.
- the attachment screen can thus be arranged between the break-up unit and the anchoring element and can be fixed in its position in two axial directions by them. In this way, the attachment screen is then fixed between the separating unit and the anchoring element fastened to the separating unit.
- the anchoring element is detachably connected to the attachment screen.
- the anchoring element can thus be manufactured separately from the attachment screen.
- the splitter unit has a splitter plate or is designed as a splitter plate.
- the water flow is above an outlet structure of the aerator ends .
- the water flow is guided through an outlet structure of the jet regulator.
- the water flow can optionally protrude from the outlet structure, in particular an outlet structure into which the outer channel of the two channels opens.
- the aerator can have at least one attachment sieve and/or at least one sieve insert in the area of the water supply.
- the at least one attachment screen and/or the at least one screen insert can have openings through which the water supply of the inner channel is guided.
- the openings can be spaced apart from the water supply. This is beneficial in order to ensure that existing attachment screens and/or screen inserts can be used with the water supply without structural changes.
- the spacing allows sufficient residual wall thickness in the components, which allows for economical production z. B. favored in plastic injection molding.
- a sieve element can be arranged and/or formed in the water supply.
- the sieve element can be molded onto the water supply.
- the respective connection can be realized, for example, by a corresponding snap connection.
- a non-detachable snap connection can prevent the attachment screen from being washed away.
- the anchoring element can be detachably or non-detachably connected to the decomposition unit.
- the respective connection can be implemented, for example, via a corresponding snap connection.
- a detachable snap connection can, for example, be characterized in that it becomes softer under load, while a non-detachable snap connection becomes more snagged under load.
- a non-detachable snap connection may be established by an included angle at the base of an undercut that is equal to or less than 90°.
- a releasable snap connection can be easier to manufacture if the demolding direction corresponds to the insertion direction of the snap connection. This is because the demoulding is then typically carried out as forced demoulding over the undercut, which is difficult if the snap connection is intended to be non-detachable, i.e. self-fixing. In this case, multi-part or moveable cores would then have to be used, which is very expensive.
- each channel of the jet regulator can have its own inlet, which is separate from the inlet of the other channel and can be charged with liquid independently of the other channel and its inlet.
- each channel separately to a liquid source assigned to the respective channel.
- one of the two channels can be connected to a source of hot water and the other of the two channels to a source of cold water. A possibly undesired mixing of the liquids within the aerator can thus be avoided.
- the jet regulator can be designed in such a way that the two channels can be used simultaneously. It is thus possible to charge both channels with liquid at the same time.
- the jet regulator can also be designed in such a way that no switching is required on the jet regulator to operate the channels.
- the two channels can, in particular if they have separate inlets and separate outlets, provide flow paths through the jet regulator that are separate from one another and/or can be used independently of one another. For example, it is possible to use the flow paths provided by the channels at the same time. This can improve the performance of the aerator and expand its uses.
- a decomposition unit can be characterized functionally, for example: it can force a flow onto a defined path in order to decouple subsequent flow conditions from upstream conditions.
- a diffuser can be characterized functionally: it can force a flow to a radial flow with subsequent turbulence.
- a sieve element can be characterized functionally, for example: it can have a rectifying effect on a have water flow.

- FIG. 8 shows the detail marked with the circle VI II in FIG. 7 in an enlarged representation.
- the figures show an aerator, designated as a whole by 1, which forms two separate channels 2 and 3 arranged one inside the other.
- a decomposition unit 4 is assigned to an outer channel 2 of the two channels 2 and 3 .
- a water guide 5 of an inner channel 3 of the two channels 2 and 3 is inserted through the decomposition unit 4 .
- the water guide 5 of the aerator 1 is designed as a water guide sleeve. It has a peripheral latching groove 6 in which the dismantling unit 4 is arranged when the water guide 5 is in the latched position of use.
- the locking groove 6 is delimited axially by two shoulders 7 and 8 of the water guide 5 .
- a shoulder 7 on the outflow side has a smaller radial extension than the other, inflow-side shoulder 8 of the water guide 5 . This makes it easier to insert the splitter unit 4 into the latching groove 6 via the shoulder 7 of the water guide 5 on the outflow side and thus to fix the water guide 5 on the splitter unit 4 of the jet regulator 1 .
- the outflow-side shoulder 7 with a smaller radial extension is also associated with an outflow-side run-on bevel 9 .
- the starting bevel 9 is designed as a starting cone. About this starting slope 9, the dismantling unit 4 during assembly of the The aerator 1 can be inserted comparatively easily into the locking groove 6 of the water guide 5 .
- the aerator 1 also has an attachment screen 10 for the outer channel 2 , which is attached to the separating unit 4 and to the water guide 5 .
- the attachment screen 10 for the outer channel is fastened to the separating unit 4 with an anchoring element 11 .
- the water guide 5 for the inner channel 3 also serves as an anchoring element 11 for fastening the attachment iebs 10 to the splitter unit 4 .
- the anchoring element 11 engages behind the splitter unit 4 on the outflow side. This can be seen particularly well in the sectional views of the jet regulator 1 according to FIGS. 6 and 7.
- the previously mentioned shoulder 7 of the water guide 5 on the outflow side which delimits the locking groove 6 of the water guide 5 on the outflow side, engages behind the splitter unit 4 .
- the separating unit 4 has a shoulder 12 on the inflow side, by means of which the attachment screen 10 is fixed axially on the outflow side.
- the attachment sieve 10 thus rests on the separating unit 4 on the inflow-side step 12 of the separating unit 4 .
- the inflow-side step 12 of the separating unit 4 grips behind the attachment screen 10 on the outflow side.
- the attachment screen 10 On the inflow side, the attachment screen 10 is secured axially by an inflow-side stop 13 of the water guide 5 .

- the dismantling unit 4 and the attachment screen 10 are connected to one another by a detachable snap connection.
- the anchoring element 11 and the attachment screen 10 are also connected to one another by a non-detachable snap connection. These non-detachable snap connections prevent the attachment screen 10 from being washed away.
- the anchoring element 11 is permanently connected to the dismantling unit 4 . This also prevents the attachment screen 10 with the anchoring element 11 from being washed out.
- the splitter unit 4 of the jet regulator 1 comprises a splitter plate 14 .

- the fitting 15 has an external thread 18 with which a threaded sleeve 19 of the jet regulator 1 is screwed for fastening the jet regulator 1 to the fitting 15 .
- a sieve element 23 is formed within the water channel 5 .
- the sieve element 23 is at a distance from the outlet end of the water guide 5, so that a water jet can recombine and then has no gaps, for example at webs. Furthermore, in this way, a tool now has to be moved twice a half way when demolding compared to a full way.
- the sieve element 23 is molded onto the water channel 5 and forms a materially homogeneous, monolithic unit with it.
- the jet regulator 1 On the outflow side of the separating unit 4 , the jet regulator 1 has further sieve inserts 20 in the area of the water channel 5 , which radially surround the water channel 5 .
- the water channel 5 is guided through openings 21 in the sieve inserts 20 , the edges of the openings 21 being arranged at a distance from the water channel 5 .
- the separating unit 4 and the attachment screen 10 also have openings 21 through which the water guide 5 is inserted.
- the two channels 2 and 3 have separate inlets 24 and 25 on the inflow side, via which they can be connected to different liquid sources. Furthermore, the two channels 2 and 3 have outlets 26 and 27 that are separate from one another on the outflow side.
- Both channels 2 and 3 can be operated simultaneously. It is thus possible for both channels 2 and 3 to be charged with liquid at the same time if required.
- the aerator 1 is designed in such a way that no switchover is necessary for the simultaneous operation of channels 2 and 3 .
- the two channels 2 and 3 provide flow paths 28 and 29 through the jet regulator 1 that are separate from one another and can be used independently of one another if required.
- the invention deals with improvements in the technical field of jet regulators.
- an aerator 1 with two separate channels 2 and 3 arranged one inside the other is proposed as an improvement, in which a water guide 5 of an inner channel 3 latches in a separating unit 4 assigned to an outer channel 2 of the two channels 2 and 3 and thus in two axial directions is fixed.
