Abstract: A flow regulator, jet regulator or backflow preventer (11) having at least two components or parts (2, 11), a first one (2) of which can be inserted into a receiving opening (12) of the second part (12). The two parts (2, 11) can be interconnected using a locking arrangement (13, 17). One part is provided with at least one locking cam while the other part (11) is provided with a locking groove which is assigned to the locking cam and is used as a counterpart. One of the parts is provided with a slot (15) or similar recess located at a distance (a) from the outer or inner circumference of the part (2) in the area of the at least one locking groove.

Abstract: A jet regulator (1) having a jet fractionating device (2) which distributes the incoming water flow into a plurality of individual jets is provided. The jet regulator (1) has at least one individual jet, from the individual jets formed by the fractionating device, which impacts on a node point (3) of a criss-crossing grid of bars (4, 5) of an outlet side downstream grid network (6). At least one node point (3) is configured as an inlet side recess of the grid network (6) and/or the jet regulator is an aerated jet regulator having a jet regulator housing (7) which includes at least one aeration opening (8) on a periphery of the housing thereof and at least one reflection projection (9) which is used to maintain the water jet at a distance from the aeration opening that is arranged on the inner periphery of the housing in the direction of flow below the at least one aeration opening (8). The jet regulator (1) provides an improved fractionating of the incoming individual jets.

Abstract: A plumbing outlet armature (2) with a liquid guide (3), which opens into a fitting outlet (4) in an area in which a plumbing functional unit (5) in the form of an insertion cartridge is provided. The outlet fitting is provided such that the clear open cross-section of the liquid guide (3) is adapted to the insertion cartridge (5) at least in the opening area of the fitting outlet (4), and the insertion cartridge (5) can be inserted into the fitting outlet (4) from the opening side and is removably held therein. The inventive outlet armature is characterized by the insertion cartridge being removably held in the fitting outlet (4) by a sleeve-shaped intermediate holder (6), which intermediate holder itself is removably held in the fitting outlet (4) by a screw or bayonet connection. The inventive outlet fitting (2) can be used with a jet regulator or with another plumbing functional unit (5) without any significant limitations of the structural clearance.

Abstract: A functional plumbing unit embodied as an insertion cartridge (2) is provided that is to be inserted into a liquid conduit (3) of a discharging plumbing fixture (4) which includes a housing (5), a jet regulator, and an attachment screen (9) located at the inlet end. The housing (5) is formed in one piece with a perforated plate located at the discharge end as part of the jet regulator, and has an external thread (10) on an outer surface thereof, with the external thread being screwable into an internal thread (13) of the dischargint fixture (4). A ring seal (12) is located adjacent to the external thread (10) at the discharge end. The length of the housing (5) is dimensioned essentially for accommodating the external thread (10) and the adjacent ring seal (12).
