摘要： A plumbing system is provided with a coupling having a chamber, an inlet passageway through which a fluid may enter the chamber from a supply, an outlet passageway through which a fluid may exit the chamber and the coupling, and a vent passageway in fluid communication with the chamber and having a vent inlet in communication with ambient atmosphere and a vent outlet in communication with the chamber. The coupling is provided between a source of liquid (e.g. a control capsule for mixing hot and cold water supplies via a user operable valve) and an outlet nozzle (e.g., a hose-connected spray head). A vacuum breaker check valve is located in the vent passageway of the coupling and includes a valve member for closing the vent inlet when pressure in the chamber is greater than pressure at the vent inlet and for opening the vent inlet when pressure in the chamber is less than pressure at the vent inlet.

摘要： A first automatic valve of a safeguard is connected in the flow path of a sanitary fitting. The diaphragm, acting as the valve body of a second valve, interacts with the valve seat and the first valve is arranged on said diaphragm. Under normal operating conditions, the second valve is closed and the first valve is opened. Under conditions allowing backflow counter to the direction of the arrow S, the first valve closes automatically, by which action the diaphragm is deformed counter to the direction of the arrow S due to the suction on the input side, which results in the second valve being inevitably opened. By this construction, water is prevented from flowing back into the feedline and the outlet is connected to the ambient air through the opened second valve and the aeration path.

摘要： A sanitary fitting includes a fitting housing which has a fixed housing part which is overlapped by a jacket element which can be swivelled about an axis. Projecting toward the front from the jacket element is a nozzle in which a guide bush is inserted. Together with the inner wall of the nozzle, the guide bush bounds a jacket space which is connected to the surroundings by a passage. Furthermore, the jacket space is communicated by an aeration passage to an annular channel which is communicated by an aeration line to an aeration aperture of a safeguard mechanism. Water fed through a feed line is mixed in a control cartridge and flows through the safeguard mechanism, connected downstream from the control cartridge, and through a pipe into a hose to a shower. In the case of conditions permitting backflow of water into the feed line, the safeguard mechanism prevents backflow and aerates the pipe and the hose while exposing an aeration aperture. Any water thereby escaping through the aeration aperture is conducted through an aeration channel into a deeper part of a sink.

摘要： The sealing arrangement comprises a seal having end sealing surfaces. The one end sealing surface bears against an annular sealing surface of a valve seat screwed into a lower part of a water faucet. The other end sealing surface presses upon a non-rotatable disk which bears against a rotary disk. The seal comprises radially outwardly projecting supporting ribs in the region of the end sealing surfaces. These supporting ribs are supported at a supporting ring of a housing of a ceramic upper part or portion. A slit spring washer bears against the seal at the inner or internal side thereof. With this sealing arrangement it is rendered possible that the seal has to be fitted into the water faucet with only a small bias or loading, because the seal efficiently utilizes the water pressure and converts or transforms such water pressure into a force which presses the end sealing surfaces with greaater compression or pressure against the annular sealing surface and the non-rotatable disk, respectively.

摘要： In a valve space surrounded by a housing is arranged a sleeve-shaped valve body made of elastomeric material. The valve body is fastened with a fastening end thereof to the housing, and a flow channel thereof is flow-connected to an inlet orifice. The valve body bears, with a middle portion of the valve body spanning a ventilation orifice, on a ventilation-valve seat formed on the housing. There adjoins the middle portion a bead which the end portion, bearing under prestressing on the valve-seat element, adjoins on the other hand. With water flowing in the direction of flow and also with an equal pressure prevailing on the inlet side and outlet side, the valve body bearing on the ventilation-valve seat prevents the outflow of water through the ventilation orifice. With a negative pressure prevailing on the feed side, the middle portion lifts off from the ventilation-valve seat, in order to ventilate the outlet orifice.

摘要： The fitting has a valve (18) for cold water and a valve for (sic) (20) for hot water. Arranged fixedly on the closure part (38) interacting with the valve seat (42) is the auxiliary valve seat (56) of the relevant auxiliary valve (52, 54). The closure element (58) can be displaced in the direction of the axis (30) from the idle position shown into the desired limiting position by displacement of the control pin (82) in the direction of the axis (78') and by rotation of the same about the axis (78'). The auxiliary valves (52, 54) are thereby opened which leads to a pressure drop in the pilot control space (40). The closure parts (38) are lifted from the valve seats (42), by which means the water can flow from the inlet (22, 22') into the outlet (48, 48'). When the valve (18, 29) is opened, the gap between the O-ring (66) and the auxiliary valve seat (56) thus becomes smaller. This results in a pressure balancing occurring between the pilot control space (40) and the other side of the closure part (38). The quantity of water flowing through a valve (18, 20) is thus determined by the limiting position of the closure element (58). The fitting thus no longer requires a mixing valve, the temperature of the mixed water flowing out through the water outlet head (28) is determined by the quantity of cold and hot water released by the valves (18, 20).
摘要翻译： 该配件具有用于冷水的阀门（18）和用于热水的阀门（20）。 与阀座（42）相互作用的封闭部件（38）上固定地布置有相关辅助阀（52,54）的辅助阀座（56）。 通过控制销（82）在轴线（78'）的方向上的位移和旋转（82）的位移，闭合元件（58）可以沿轴线（30）的方向从所示的空转位置移动到期望的限制位置 与轴线（78'）相同。 辅助阀（52,54）由此被打开，导致先导控制空间（40）中的压降。 封闭部件（38）从阀座（42）提升，通过这种方式，水可以从入口（22,22'）流入出口（48,48'）。 当阀（18,29）打开时，O形环（66）和辅助阀座（56）之间的间隙因此变小。 这导致在先导控制空间（40）和封闭部分（38）的另一侧之间发生压力平衡。 因此，流过阀门（18,20）的水量由封闭元件（58）的限制位置决定。 因此，配件不再需要混合阀，通过出水头（28）流出的混合水的温度由阀（18,20）释放的冷热水量决定。

摘要： A housing for a discharge valve includes a hollow cylindrial socket which projects in the radial direction, and in which a siphon an actuating pin for control of the valve stopper is mounted in a leakproof manner in a ball-and-socket joint arrangement. A spherical part enclosing an intermediate portion of the actuating pin is received in a ball socket recess in a holding element, which is snapped onto the socket in a leakproof manner. The ball socket recess has on the outer side a spheri-zone type sealing surface on which an O-ring slides. A set of fingers of the holding element partially enclose the spherical part and press it with a specific force against the sealing surface.
