  • Patent number: 5960828
    Abstract: A sanitary fitting contains in a common basebody thereof a flow control valve and a thermostatic valve. The flow control valve contains a valve for the cold water and a valve for the hot water. These valves are arranged upstream of the thermostatic valve in the direction of flow. Both valves are actuated by a common control valve. In addition, the flow control valve may be used for selecting several outlets.

  • Patent number: 5647530
    Abstract: A sanitary valve contains a valve housing with a fixed control surface and a hot water intake. In the valve housing is provided a control element, which controls the water quantity leaving the valve. According to the invention the sanitary valve contains a scalding protection, which is arranged and constructed on the control element in such a way that on exceeding a predetermined temperature it reduces or prevents the passage of water through a hot water-carrying opening.

  • Patent number: 5580031
    Abstract: A stop valve which is in particular constructed as a valve top for a sanitary fitting, contains an actuating member constructed as a rotary spindle. The actuating member, which is held in axially non-displaceable manner, engages with a hexagonal neck in a closing body, whose external thread engages in an internal thread of the valve top. The closing body has a closing face cooperating with a valve seat. The valve seat is displaceable to a limited extent in the axial direction and contains a rubber-elastic member.

  • Patent number: 5277454
    Abstract: In a bath rim fitting or other fitting, in which a shower hose extends through a plate or the like and whose back is difficultly accessible, it is proposed to connect the shower hose to the fixed pipe with the aid of a pressure hose. The pressure hose is sufficiently long that it can at least be drawn up to the plate opening by pulling on the shower hose, so that it is possible to replace the latter in front of or outside the plate.

  • Patent number: 4733688
    Abstract: A mixer valve has a valve cartridge arranged in interchangeable manner in a valve casing. A fixed control disk and a movable control disk can be moved counter to one another by an operating element in said valve cartridge. The latter has a roughly tubular casing, which is closed on the outside by a cup-shaped sleeve and on the inside by a cartridge bottom. As a result of this construction, the cartridge can be replaced particularly easily.

  • Patent number: 4630643
    Abstract: A valve contains a connection for connecting to a tube of a supplemental shower head or spray nozzle, the connection preferably containing a check valve. In the case of the preferred embodiment, the connection for the supplemental apparatus is arranged in the handle of the operating lever connected to a spherical plug valve. The water is supplied to the handle through the hollow connecting rod, from the interior of the spherical plug.

  • Patent number: 4617965
    Abstract: A control disk insert for a one-lever mixer valve contains two preferably, planar disks, whereof one fixed disk has at least one opening zone for hot water and at least one opening zone for cold water. The control disk facing the fixed control disk and movable with two degrees of freedom can both completely close and continously completely open the opening zones in the fixed control disk. The opening zones of the fixed control disk and the control edges of the movable control disks are constructed in such a way that the control disk insert has two completely separated, independently operating, but mechanically coupled controlsystems. Both control systems can be used for a common water outlet, or for two separate water outlets.

  • Patent number: 4449551
    Abstract: A single mixing valve has a ball-like valve plug with hot and cold water inlet ports and outlet ports and a valve housing having a valve seat face of the same form as the plug. The housing has inlet ducts for the hot and cold water to be mixed and an outlet duct for the mixed water, the ducts porting into the face. A driving part is joined with the plug and is able to be rocked therewith for changing the rate of outlet of water from the valve and to be moved for changing the mixing ratio of the hot and cold water. The driving part is limited in its rocking motion to motion about a rocking axis running through a middle point of the plug and is limited to turning about an axis of turning running through the middle point. The valve has a guide plate, which may be turned in a plane parallel to the rocking axis of the driving part, with same in relation to the housing. The plate has a slot in which the driving part is keyed while being able to be moved along the slot.

  • Patent number: 4352369
    Abstract: This mixing valve has a spherical plug to be operated by an operating rod, having communicating inlets and outlets which differ from one another each as to number and arrangement, formation and/or in size, so that the operating direction for varying the mixing ratio is reversed when the plug is rotated 180.degree..
