Abstract: A sanitary outlet fitting including a water outlet (2) and a jet regulator (1) which is associated with the water outlet and includes a jet regulator housing (3) with integrated components. The jet regulator housing can be inserted into the water outlet by an axial insertion movement and includes a holding element (6) provided with at least one radially mobile projection (10) for connecting to the water outlet. The outlet fitting includes either a locking element (8) that can be actuated from the outside without using a tool for selectively blocking and releasing the holding element, or an unlocking tool (65) can be inserted into the annular space (68) between the inner peripheral edge of the water outlet and the outer peripheral edge of the housing by an axial insertion movement. The insertion movement of the unlocking tool can be converted into a radial movement of the at least one projection of the holding element from a functional position into an unlocking position.

Abstract: The invention relates to a backflow preventer (1) integrateable into a gas or liquid pipeline (2). The inventive backflow preventer consists of a closing body (3) which is embodied in the form of a hollow body which is open on a drainage side thereof and defines a passage channel (5) between itself and the central counterpart (4) opposite thereto. Said closing body (3) is displaceable by a flow medium flowing through the passage channel (5) in a flow direction (Pf 1) from a sealing contact thereof with said counter part (4) of the closing body to the open position thereof against the opposing force of elasticity and o r stability thereof. Said backflow preventer (1) is easily producible even with a small number of components and is characterised by a high flow and low pressure loss.

Abstract: A backflow preventer (1) is provided that, in an insertable housing (2) thereof, includes a valve member (6) located in a housing interior (5). The valve member (6) sealingly rests against a valve seat (7) in the closed position thereof while being movable from the closed position thereof into the open position thereof counter to a restoring force. The interior (5) of the housing is provided with an interior section (A) which has an interior cross section that is larger than the outer circumference of the valve member in the movement zone of the valve member (6).

Abstract: A backflow preventer (1) having a mounting housing (2) that is inserted into a fluid conduit (3) is provide and includes at least one sealing ring (4) which is supported within an annular groove (5) located on the outer circumference of the mounting housing (2) and has a sealing effect between the mounting housing (2) and the fluid conduit (3). The backflow preventer provides that the sealing ring (4) can be moved counter to a restoring force from a sealing position into a leakage position so as to compensate pressure when the backflow preventer (1) is closed and a fluid volume is sealed on the outflow side, thereby conteracting an excessive increase in internal pressure.

Abstract: A sanitary fitting (1) formed from a multi-wall housing (2) which can be inserted into a sanitary water pipe is provided that has at least two adjacent walls (6,7) surrounding an inner region (8). The fitting includes a checj valve , and one wall of the housing (2) is a tubular wall (7) formed of a flexible and/or elastic material. In order to relieve pressure when the check valve is closed and the fluid volume is sealed in on the outflow side, the housing wall (7) can be moved towards the adjacent housing wall (6), compressing the at least one inner region (8), or can be spaced apart from the adjacent housing wall (6) or moved away from same, enlarging the at least one inner region (8).

Abstract: An interchangeable sanitary part in the form of a check valve including an outer housing (3) which can be inserted into a fluid line and has at least one peripheral seal (20, 21) on its outer circumference, which seals the outer housing (3) and the fluid line against each other. In order to avoid using additional O-rings, the at least one seal (20, 21) for providing linear or planar sealing is produced from the same material as the outer housing and forms a single element with the outer circumference of the housing. A least one peripheral sealing lip (8) located on the inner surface of the outer housing (3) is provided which is formed of the same material as the outer housing. The free end of the sealing lip (8) protrudes in such a way that, when the check valve is closed, the lip acts on the closing part (4) or the inner surface of the outer housing (3) in a sealing manner.

In another embodiment of the invention, an integratable part is embodied as a backflow preventer, and at least one peripheral sealing lip (8) forms one element with the inner surface of the outer housing (3) or the closing part (4), mounted on the same, and consists of the same material as the surface or closing part.

Abstract: The invention relates to a backflow preventing check valve (1) comprising a housing (2) in which a closing member (3) is arranged. The closing member is moveable between a closed position and an open position and is disposed on a valve seat with a sealing area in the closed position. A pressure-compensation device is provided for when the backflow preventing check valve is closed and a volume of fluid is sealed off on the outflow side. In order to counteract an undesireable high pressure load when the check valve is closed, the outflow area defined by the closing body (3) in a closed position is joined to at least one pressure compensation chamber (6) whose receiving volume corresponds approximately to the expansion volume of the sealed-off fluid and which is disposed outside the area which is defined on the outflow side.
