Abstract: In order to simplify the manufacture of an insert part, which has two web structures, each of which forms a plurality of webs, it is proposed that the insert part is manufactured by a molding process in such a way that the two web structures touch each other in respective contact surfaces, but nevertheless remain separated from each other by a mold parting plane. This has the technical advantage that the respective outer contour of the webs of the respective web structure can be defined exclusively with a respective mold part without an offset of the respective other mold part having a negative effect on the shaping of the webs.

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: A tool (1) and a method for assembling and/or for disassembling a sanitary insert part (2), in particular a sanitary outflow orifice (3), are provided. Here, the tool (1) is designed with a latching element (4) and/or mating latching element (5) for a preferably releasable and/or captive connection (6) to the sanitary insert part (2).

Abstract: A joint (1) having a fluid line (9) disposed in the interior of the joint (1) is provided, with the joint (1) including a first joint element (2) and a second joint element (3) for receiving the first joint element (2), the first joint element (2) in the second joint element (3) being freely pivotable in space about a pivot point. The first joint element (2) and/or the second joint element (3) include an anti-twist device which prevents the first joint element (2) rotating within the second joint element (3).

Abstract: A sanitary fitting (1) having a fitting housing (2) in which a valve (5) is disposed, an outflow pipe (11) in which an outflow piece (13) is disposed and which is connected to the fitting housing (2), and an outflow hose (15) which fluidically connects the outflow piece (13) to the valve (5). The outflow pipe (11) is designed to be pivotable relative to the fitting housing (2); the outflow hose (15) has, at a location spaced apart from both its ends, a fixed deflection (16); and the fitting housing (2) has a duct (17) in which the outflow hose (15) is routed and in which the outflow hose (15) is rotatable about an axis running along a pivot axis of the outflow pipe (11).

Abstract: An aerator (1) having a housing (2) and a jet-splitting device (3) arranged or formed in the housing (2) for splitting an individual jet into a plurality of separate liquid components. The aerator (1) has at least two flow channels (4), which are oriented obliquely in such a way that the outlet directions (12) defined by the flow channels (4) meet each other. An insert part (5) is inserted into a hole (6) in the main body (28) of the jet-splitting device (3), which hole is oriented in particular in the longitudinal direction of the housing (2), such that the hole (6) is divided into the at least two obliquely extending flow channels.

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 outflow unit (1) to be used in a water dispensing device (20), having a water supply (3) and a water outlet (4), which sanitary outflow unit includes at least one holding element (11) that can be switched between a release position and a holding position, wherein, in the holding position, a peripheral contour (18) of the sanitary outflow unit (1) is enlarged by the holding element (11). The holding element (11) includes in particular a bending element (12) having a holding lug (13) which, in the holding position of the holding element (11), engages behind a wall (22) of an installation opening (21) in the water dispensing device (20).

Abstract: A hose connection (1) having at least one hose receptacle (3a), into which a hose end (4a) can be introduced, wherein a clip (6) extends through the at least one hose receptacle (3a) in order to engage into a clip receptacle (9a) of the hose end (4a). The clip (6) is designed to be self-retaining at the at least one hose receptacle (3a).

Abstract: A hose assembly (1) is provided having a structure (2), in which the structure (2) has circumferential ribs (3), the axial extent of which varies, preferably periodically, along a circumference, and locally limited gap-filling elevations (4), as a result of which, a braiding impression is produced, without a separate braiding of the hose assembly (1) being carried out. The structure (2) is applied by at least two embossing dies (7), in particular embossing rollers (8), which are rollable on the hose assembly (1), in particular are rollable in synchronism on the hose assembly, and are part of an extrusion process.

Abstract: A method for removing a jet regulator from a fixture outlet, a jet regulator and to a set consisting of a jet regulator and a tool are provided, wherein the jet regulator has a housing and a latching element mounted movably on the housing. The latching element is adjustable by a force transmission from a spring element, which is arranged inside a cutout of the housing and is accessible from outside the fixture outlet, to the latching element. The latching element, in its rest position, protrudes over the housing in order to hold the jet regulator in the fixture outlet. A tool for removal purposes is inserted in an insertion direction into the fixture outlet, and the spring element is acted upon with the tool during the insertion operation until the latching element releases the jet regulator.

Abstract: A jet regulator (1) that includes, on the outflow side of a splitter unit (2), a plate-shaped carrying structure (43), from which flow obstacles (5) project on both sides into a mixing space (3).

Abstract: A pressure limiter (1) such as may be used, in particular, in sanitary water supply systems. So that the pressure limiter (1) may also be reliably used in water-carrying systems in which contamination of the water flow from particles, for example from sand grains, is likely, the pressure limiter (1) has guide faces (8), which have a cross-sectional taper (9) in at least one direction of a displacement movement of a sleeve (4) of the pressure limiter (1).

Abstract: In order to simplify the operation of a valve assembly (2) which includes a plurality of valves (3) that have respective activating elements (8) which serve for in each case manually opening the valves (3), the activating elements are temporarily blocked with the aid of at least one shut-off part (6) so that an activation of at least one of the other valves (3) of the valve assembly (2) is currently precluded.

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).
