Abstract: A sanitary insert part (1), with at least one flow-determining functional unit (2) and a diffusor (4) arranged in the flow direction (3) after the flow-determining functional unit (2), the diffusor (4) having a diffusor space (5), the diffusor space (5) is partially limited by an impact face (6) which deflects water flowing into the diffusor space (5) in a lateral direction. The diffusor space (5) has several outlet openings (7), and the impact face (6) is adjoined by a drainage ramp (8), which allows water impinging on the impact face (6) and draining therefrom to run off in the position of use in the direction of the outlet openings (7).

Abstract: A jet regulator (104) that has a jet regulator housing (1) which on the housing external circumference thereof has an external thread (2) for screw-fitting into an internal thread (3) in the water outlet (4) of a sanitary outlet fitting. The jet regulator (104) includes a housing part-region of the jet regulator housing (1) that is disposed on the outflow side of the external thread (2) in the direction towards the internal circumference of the water outlet (4) that is angled in such a manner that a drainage annular space (8) is formed between said housing part-region and the internal circumference of the water outlet (4).

Abstract: A jet regulator (1) which can be mounted on the water outlet of a sanitary outlet fitting and has a jet regulator housing (2), in which a jet splitter (3) is provided, which has splitter openings (17) for dividing the water flowing through into individual jets, and at least one insert part (5), which has a grid structure (6) consisting of two sets of parallel webs (7; 8) which touch one another or intersect at crossing nodes (9). In the jet regulator (1), the sets are arranged in two levels offset in the longitudinal direction of the jet regulator; the mutually parallel webs (7) of an inflow side set have a round or rounded web cross-section, and the webs (8) of an outflow side set have a flattened portion (10) on their inflow side and are rounded on their outflow side (11).

Abstract: In an outflow structure (10) of a jet regulator (1), holes (17, 19, 25) are formed in the edge region of a regular arrangement (12) which are enlarged with respect to the regular arrangement (12), in order to avoid the formation of small holes (17, 19, 25) in the edge region.

Abstract: A sanitary insert (1) in which the overall cross section of the aeration ducts (9, 18, 22, 23) of a jet aeration unit (3) is reduced by a ratio to the outer circumference of a mixing chamber (6) so that an air flow captures a leakage flow on the seal-free outer circumference of the insert (1) and transports the same into the mixing chamber (6).

Abstract: A sanitary insert part (1), with at least one flow-determining functional unit (2) and a diffusor (4) arranged in the flow direction (3) after the flow-determining functional unit (2), the diffusor (4) having a diffusor space (5), the diffusor space (5) is partially limited by an impact face (6) which deflects water flowing into the diffusor space (5) in a lateral direction. The diffusor space (5) has several outlet openings (7), and the impact face (6) is adjoined by a drainage ramp (8), which allows water impinging on the impact face (6) and draining therefrom to run off in the position of use in the direction of the outlet openings (7).

Abstract: A sanitary insert (1), in particular for insertion. into a faucet outlet, and/or into a water conduit, including at least one housing part (2) which is open at one side and has a receiving space (3) that is accessible via the open side, at least one insert screen (4, 5) which is inserted into the receiving space (3) of the at least one housing part (2), at least one splitter unit (6) which is arranged upstream of the at least one insert screen (4, 5) in a flow direction (7) of the fluid, and at least one orientation aid (8, 9). At least one mating orientation aid (10, 11) corresponding to the orientation aid (8, 9) is formed on the at least one insert screen (4, 5).

Abstract: In an outflow structure (10) of a jet regulator (1), holes (17, 19, 25) are formed in the edge region of a regular arrangement (12) which are enlarged with respect to the regular arrangement (12), in order to avoid the formation of small holes (17, 19, 25) in the edge region.

Abstract: A jet regulator having a sleeve-shaped jet regulator housing which is assembleable on the water outlet of a sanitary outlet fitting, and having a wall which supports a perforated structure that forms the outlet end side of the jet regulator and which in the jet regulator housing is pivotable between a use position, in which the perforated structure extends transversely across an outflow-side sleeve opening of the jet regulator housing, and a cleaning position, in which the water flowing through the jet regulator housing can flow out on both sides of the wall through opening gaps formed between the wall and the neighboring housing internal circumferential wall. The wall has a spherical-layer-shaped external circumference and via which it is pivotably mounted in a joint socket provided on the housing internal circumferential wall of the jet regulator housing. A handling element extends from the wall and is latchable on the outflow-side housing end side of the jet regulator housing.
