Abstract: A sanitary insert unit (1), which can be inserted into a discharge fitting is provided, comprising a substantially conically-shaped upstream sieve (2) with a downstream-located throughflow regulator (3) and a jet regulator (4) in a direction of flow. The throughflow regulator (3) is arranged substantially inside the inner area (6) of the insert unit, which is defined on theupper side by the upstream sieve (2). The throughflow regulator (3) has a cross-sectional shape that is substantially adapted to the cross-sectional profile of the upstream sieve (2). The throughflow regulator (3) has a rising sloping surface (9) which rises gradually in a radially inward manner from an outer, particularly annular, edge area and which leads to a control gap (10) or a similar throughflow opening that leads to the jet regulator (4). The rising sloping surface (9) and the upstream sieve are spaced apart from one another.

Abstract: A sanitary washing unit (1) having a hand washing basin (1) and at least one sanitary outlet armature (3). The sanitary outlet armature (3) has at least two spaced apart outlet openings (4) to produce visually separated outward flowing water streams (5). The washing unit (1) of the invention has the feature that the longitudinal axes of the outlet openings (4) that determine outflow direction of the water streams (5) are arranged at such an angle that adjacent water streams (5) overlap at least in sections in the atmospheric area between the outlet opening (4) and the impact zone of the water streams (5) in the wash basin (2) or that the distance between the water streams increases. The risk of excessive splashing in the wash basin area is considerably reduced by the washing unit (1).

Abstract: A cartridge insert for insertion in a fluid line is provided having a cartridge housing within which is located at least one backflow inhibitor and downstream at least one flow regulator. The backflow inhibitor has a closing element, which, in a closed position thereof, lies tightly sealed on a valve seat of the cartridge housing and which may be displaced from the closed position against a return force into an open position. A downstream guide pin projects from the closing element, and extends into a guide opening of a central regulator core of the flow regulator, and the flow regulator is formed from a regulator element made from an elastic material that surrounds the regulator core, which rests on an annular shoulder and defines a control gap, which changes with pressure between the above and an opposing enclosing wall.
