Abstract

The present invention relates to a jet regulator ( 2 ) has a jet regulator housing with at least two housing parts ( 5, 6 ) which are rotatable relative to one another and of which an inflow-side first housing part ( 5 ) is mountable in a rotationally fixed manner on the water outlet of a sanitary outlet fitting and of which an outflow-side second housing part ( 6 ), at least at its outflow-side housing outer circumference, is configured as a handle or is connected to a handle, wherein the first housing part ( 5 ) has a jet splitter ( 7 ) having a plurality of splitter openings ( 8 ), wherein spaced-apart jet ducts ( 9 ) are provided on the housing inner circumference of the second housing part ( 6 ), and wherein the individual jets coming from the splitter openings ( 8 ) are guided through the jet ducts ( 9 ) and formed into an annularly circumferential outlet jet pattern in a first rotary position of the housing parts ( 5, 6 ), and are deflected in the housing interior of the jet regulator ( 2 ) to a central outlet opening ( 10 ) in the jet regulator housing in a second rotary position. The jet regulator according to the invention is characterized in that a rotary latch having at least one latching tooth ( 13 ) is provided, said latching tooth ( 13 ) being integrally formed on a duct wall facing the housing interior of the jet regulator housing and said latching tooth ( 13 ) interacting with a latching profile, and in that a lattice or grid structure that extends over the central outlet opening ( 10 ) is integrally formed on the outflow side of the second housing part ( 6 ).

2. The jet regulator as claimed in claim 1 , wherein the at least one latching tooth ( 13 , 13 ′) comprises at least two latching teeth, at least two of the jet ducts ( 9 , 9 ′) are each provided with a latching tooth.

3. The jet regulator as claimed in claim 1 , wherein the annularly circumferential outlet jet pattern is formed by individual jets that are arranged orbitally and emerge from the jet regulator ( 2 ′) separately from one another.

4. The jet regulator as claimed in claim 1 , wherein the annularly circumferential outlet jet pattern emerges from the jet regulator ( 2 ) as an annular wall.

5. The jet regulator as claimed in claim 1 , wherein the flexible tongue ( 14 ) of the at least one jet duct ( 9 ) is separated on both sides from adjacent duct side walls by wall incisions ( 15 , 16 ).

6. The jet regulator as claimed in claim 1 , wherein the latching profile provided on the circumferential wall of the first housing part ( 5 , 5 ′) has latching cams ( 12 , 12 ′) which are arranged alongside one another in the circumferential direction and of which in each case two adjacent ones of the latching cams ( 12 , 12 ′) bound a latching indentation ( 11 , 11 ′) between one another.

7. The jet regulator as claimed in claim 6 , wherein each said subregion, bearing in each case one of the latching cams ( 12 ′), of the wall is configured as a flexible tongue, and wall incisions ( 15 ′, 16 ′) are provided between adjacent flexible tongues in a region of each said latching indentation ( 11 ′).
