摘要： To the housing part of a backflow-preventer for a sanitary device there is fastened an outer sleeve, made from elastomeric material, exhibiting a sleeve section which is distanced from the housing part. The outer sleeve embraces an inner sleeve which is fixedly supported to the housing and includes a supporting section, which is dimensioned such that the inner sleeve, when acted on by water flowing in the direction of flow, cannot fold inward. The sleeve section bears, under pretensioning, against the supporting section and is expanded by the pressure of the water so as to clear an opening between the sleeve section and the inner sleeve. If the water current is interrupted, the outer sleeve immediately bears again against the inner sleeve. The end sections of the inner and outer sleeves are configured like a sealing lip. The backflow-preventer prevents water from flowing back, even under the least underpressure on the feed side. Moreover, it is not sensitive to foreign bodies.

摘要： The mixing fitting (10) has a shutoff valve (22) for hot water and a shutoff valve (24) for cold water. These shutoff valves (22, 24) are constructed as diaphragm valves and each have an auxiliary valve (62, 62') provided in the pilot control space (50). To operate these auxiliary valves (62, 62'), permanent magnets (76) are provided which can be swivelled about the axle (80') into and out of the range of action on the closure elements (64) of the auxiliary valves (62, 62'). To open the shutoff valves (22, 24), the swivel body (78) is swivelled by means of the drive (94) with the permanent magnets (76) into the region of the closure elements (64), by which means the latter are pulled toward the permanent magnets (76) with the auxiliary valve (62, 62') opening. The pressure in the pilot control space (50) drops and the shutoff valve (22, 24) is opened by the closure part (44) being lifted from the valve seat (40). If the permanent magnets (76) are again swivelled out of the range of action on the closure elements (64), the latter close the auxiliary valves (62, 62'), which results in the pressure in the pilot control space rising again due to the passage (52). The closure part (44) again comes to rest on the corresponding valve seat. The shutoff valve (22, 24) is thus closed.

摘要： The fitting has in each case a hydraulically operable shutoff valve (40, 42) for hot and cold water. The diaphragm-shaped closure part (56) interacts with the valve seat (52). Provided on the side opposite the valve seat (52) is a pilot control space (60) which is connected through the passage (62) to the annular channel (48) and the corresponding feedline (20). Via control lines (86'), each pilot control space (60) is connected to the outlet line (24) via an auxiliary valve (70'). The two auxiliary valves (70') are constructed on a ceramic disk valve (72) and can be operated jointly. When the auxiliary valves (70, 70') are closed, the pressure in the pilot control space (60) corresponds to the pressure in the annular channel (48), the shutoff valves (40, 42) are closed. By rotating the operating shaft (86) the two auxiliary valves (70') are opened, by which means the pressure in the pilot control spaces (60) drops. The closure part (56) is lifted from the relevant valve seat (52) and the shutoff valves (40, 42) are opened. When the auxiliary valves (70') are closed by rotating the operating shaft (86), the pressure in the pilot control spaces (60) rises again, by which means the shutoff valves (40, 42) are closed. The joint operation of both shutoff valves (70, 70') requires extremely little energy.

摘要： Water supplied from a mixing faucet or combination set via an inflow chamber to a change-over valve effects by impact pressure that a double-sided valve member--as a result of an asymmetrical arrangement between a first valve seat and a second valve seat--moves to the first valve seat, thereby blocking the supply to a shower outlet. Therefore, the water is conducted via the second valve seat into a bath-tub outlet. By actuating a draw-button, the double-sided valve member is reversed in order to block the bath-tub outlet and release the shower outlet. Impact pressure now effects self-locking in this position. When the water is turned off and impact pressure no longer prevails, the two-sided valve member thereupon moves into an inoperative positon by the force of two mutually counteracting springs. The conduit leading to the shower is automatically emptied by means of an annular gap remaining between the first valve seat and the double-sided valve member. It is thus precluded that bacteria can multiply or be reproduced in standing water.
