Abstract: An actuating device for a mixing valve having a valve housing and a movable valve member includes a hand lever which is partly accommodated within a housing and operatively connected to the valve member. The hand lever is movable about two axes perpendicular to each other and is provided with an arc which projects through a slot into the interior of the housing. In order to minimize the size of the slot and to obtain an attractive visual appearance, the arc is provided with an inner contour aligned with the respective housing portion and having a radius extending from a fixed point of one of the axes.

Abstract: An operating mechanism for a fluid flow shifting valve of a sanitary mixing faucet assembly or the like of, for example, a bathtub and shower, which raises or lowers a flow shifting valve stem guided in the mixing faucet body so as to shift the fluid flow between two outlets, comprises an operating lever pivotally connected to the valve stem and also attached pivotally to a preferably rodlike, centrally located pivot bearing, wherein the lever arm of the operating lever is proportioned so that a reduced applied force is sufficient to effect a shift in fluid flow. Advantageously the operating lever may be provided with a press contact or a lever cap attached to its top for ease of operation. The operating mechanism is essentially integrated in the mixing faucet body so that it does not protrude significantly.

Abstract: In a pressure compensated mixing valve, the hot and cold water lines each include electrically actuated valves. Each valve has a movable valve rod coupled to a valve cone via a deformable member. The deformable members are acted upon such that as water pressure increases or decreases, the deformable member moves the valve cone to a more closed or opened position.

Abstract: A valve slide plate of ceramic oxide or a similarly suitable material with at least one overflow passage in the form of an aperture and which is movable on a rigidly mounted base plate with fluid passages by a driver element includes a flexible seal which is interposed between the valve slide plate and the driver element and is vulcanized to the valve slide plate, and which engages the driver element with only a minimal contact pressure determined by the prevailing pressure of the liquid flowing through the valve.

Abstract: A mixing valve of the type utilizing a fixed valve seat disk and a movable control disk is described. The axis of rotation of the control disk in the valve housing is offset in relation to the center of the valve seat disk towards the inlet passages. With this arrangement the pivot angle for setting the mixture ratio is increased.

Abstract: A volume control valve in accordance with the invention is formed in a valve body which is adapted for insertion into a valve fitting. The valve body includes a valve seat insert and a valve disk. A sealing element is disposed between the valve seat insert and the valve fitting. The sealing element is carried on a supporting piece such that a first face of the sealing element is disposed on one side of the supporting piece and a second face is disposed on the other side of the supporting piece. The supporting piece is held against shoulders in the body such that the valve seat insert is prestressed by a predetermined amount by the first face. The second face is deformable against the fitting to accomodate different fitting depths.

Abstract: Valve, in particular for the sanitary engineering field, with two flat and smoothened plates, one on top of the other, held in a housing and movable towards each other as a valve element whereby the plates have one or more through-apertures for one or more media.To simplify installation and reduce costs, the two plates are combined into one pack with appropriate sealing and sliding elements, the pack being bedded in a housing formed from two semi-monocoques having apertures for a valve actuating element and the inlet and outlet lines capable of insertion into an inlet and outlet flow device with pre-tensioning, whereby the contact surfaces of the two semi-monocoques are matched to the individual thickness of the pack by material deformation and are inseparably connected the one with the other.

Abstract: A shower head which provides a pulsating output utilizes a swirl chamber to impart a swirl to the water flow. The use of water driven parts is thereby eliminated.

Abstract: A mixing valve arrangement for producing temperature controlled water wherein an electromagnetically actuatable supply valve is coupled in each of the hot and cold water supply lines is described. Electronic control loop circuits generate a temperature control signal from both a temperature preselector and a temperature detector and a volume control signal from both a volume preselector and a mixed water flow volume detector. An electronic decoupling circuit is interposed between the two control loop circuits and the valve actuating circuits to derive control signals representative of the degree of opening of the two supply valves from the temperature and volume control signals.

Abstract: A mixing valve is provided with modular self contained units for controlling the volume, controlling mixtures ratio, and providing pressure balancing. Each unit may be separately replaced.

Abstract: PCT No. PCT/DE78/00020 Sec. 371 Date May 4, 1979 Sec. 102(e) Date May 4, 1979 PCT Filed Aug. 14, 1978 PCT Pub. No. WO79/00134 PCT Pub. Date Mar. 22, 1979Mixer valve for sanitary engineering with a slide plate, adjustable by means of a handle, to regulate the mixture ratio and outflow volume of tap water.For the precise and comfortable setting of the mixed water temperature in the preferred setting range, particularly between 30.degree. and 45.degree. C., and for the simple, space-saving and cost-favorable manufacture of the device, it is proposed to arrange the slide-plate parallel to the center axis in the valve housing and mount it in a movable and slewable manner around a rotational axis displaceable parallel to the center axis, whereby the slide plate is guided by a head piece displaced in relation to the center axis and protruding from the valve housing on a lever mounted to allow upwards and downwards movement in the jacket of a head housing mounted rotatably around the center axis.

Abstract: A valve slide plate is described in which flow noises are reduced. A flow passage for regulating through-flow volume or mixture is recessed in the surface of the valve plate. The flow passage is of expanded cross-section within the plate.

Abstract: A water level control system for use with bath tubs includes a capacitive proximity switch disposed external to one wall of the bath tub. The vertical position of the switch is adjustable. The switch generates a signal when the water level is approximately that of the switch. The signal is used to control a water supply solenoid and/or an alarm indication.
