Abstract: A shower partition of the type which is attached to a wall and which can be swiveled as well as swung open and closed, between a rest position and an open position in which the shower partition forms an enclosed shower stall in conjunction with the wall to which it is attached. The shower partition includes a pair of separate subunits, each of which includes a plurality of segments which are hinged with one another. A first end of each subunit is attached to the wall in spaced apart relationship with respect to the first end of the other subunit, and opposite, second ends of the subunits abut one another, when opened, to form the shower stall. When the subunits are opened to form the shower stall, the inner segments are able to fold outward to the rest position while the outer segments are able to fold inward into the rest position but are blocked from folding further outward.

Abstract: A suitable design is given of a closure damper for a sanitary water fitting, especially in the form of a single-handle mixing unit, with a casing, an activation handle, and with a control unit presenting a disk, piston, balls, or the like, as well as a closure damper to extend the closure time and reduce the closure rate arranged between the handle and the fitting casing, whereby the closure damper is designed as a piston and cylinder unit. It is provided for watertight membrane (20) to surround piston and cylidner unit (16, 17) outside, connected with cylinder (16) on the one hand and piston (17) on the other, watertight in both cases, which forms membrane chamber (24) when piston (17) is pushed in, and a flow connection exists between inside space (25) of cylinder (16) sealed against piston (17) and the outside of cylinder (16) encircled by membrane (20).

Abstract: In a sanitary water valve having a control member which consists of three disk cams arranged above one another and which is enclosed by a casing, whereby the lower and the upper disk cam are stationary and the middle disk cam is moveable relative to the stationery disk cams by an actuator which engages in it, whereby the actuator, which is arranged in two planes to tilt and to swivel, passes through the casing lid and the upper stationery disk cam, the bearing of the actuator is to be improved. To this end, the actuator 23 is seated on bearings (30) which are arranged on casing 12, which encloses the control member 11, in such a manner that the fulcrum of the actuator (23) is situated in the plane of the casing lid (15).

Abstract: A sanitary mixing valve for controlling the flow and mix of hot and cold water supplied respectively from a hot water inlet and a cold water inlet. The valve includes a valve body coupleable to the hot and cold water inlets and having a water outlet. A disk packet is supported on the valve body and includes a control disk. The control disk includes a mixing chamber for receiving a mix of the hot and cold water. A temperature-dependent control element is positioned on the control disk to directly measure the temperature of the mixed water in the mixing chamber. The temperature of the water emerging from the water outlet is regulated according to the measured temperature.

Abstract: An electronic temperature control method and apparatus unit for a mixing valve for plumbing fixtures. The loop gain in the control unit is at least approximately inversely proportional to the instantaneous slope of the characteristic curve of the mixing valve, and the slope of the characteristic curve is determined from the instantaneous conditions of valve opening, hot and cold supply temperatures and mix temperatures.

Abstract: An assembly is provided for the prevention of scalding in showers and other such installations. The assembly includes a valve assembly within a mixed water supply line and a temperature sensitive element for controlling the operation of the valve assembly. The valve assembly is preferably designed to allow some leakage when in the closed position.

Abstract: A sanitary fitting and plumbing fixture, such as a sink, bathtub or lavatory, are so arranged such that the actuating lever and spout are disposed in recesses formed in the plumbing fitting, the spout being constructed so that when water is flowing through the fitting, it is discharged from the spout in a waterfall-like fashion.

Abstract: An electric immersion thermometer, for use in a device such as a mixing faucet, is disclosed. The immersion thermometer includes a body which houses a temperature sensing assembly in which the sensing element is encapsulated or laminated in a plastic sheath or jacket. The encapsulating sheath being formed from a plastic thermally shrinking tubing and a plastic bracket for mechanically supporting the thermometer. A plastic insert also can be mounted in the body of the immersion thermometer that is coupled to the faucet. The plastic jacket has good heat conducting and electrical insulating properties.

Abstract: A single-handle sanitary valve, of the type having valve means including a movable control disc mounted in face-to-face seating contact with a stationary valve seat, is disclosed. The valve seat disc includes temperature attentuating means operatively coupled between the hot and cold water inlet openings of the stationary valve seat disc and the hot and cold water supply conduits so that when the mixing valve is in its operative mode, a relatively large movement of the handle produces only a relatively small change in mixed water temperature, thereby achieving a greater so-called comfort zone.

Abstract: A top cartridge for an individual, sanitary, dual-control, shut-off valve is provided. The cartridge includes an upper stationary and a lower rotatable disk, each disk including port apertures. The disks are arranged with a defined clearance in the longitudinal direction of a driver pin. A driver is welded to the pin and includes a finger which engages the rotatable disk. The upper end of the pin is pressed within a spindle. The spindle is positioned within a bushing to prevent calcination and corrosion thereof. A seal is provided near the bottom end of the pin between the driver and the rotatable disk.

Abstract: An electronically operated mixing valve is disclosed wherein a combination of a control module which houses the electronics for electrically operating a valve module having one or more valves for mixing, shut-off and distribution of mixed water which is in contact with at least one temperature sensor, and an electromechanical motor module which is electrically connected to the valve module for automatically operating the one or more valves.

Abstract: The invention relates to a sanitary single-handle mixing valve having control elements composed of at least two discs, one of which serves as a fixed valve seat disc with two inlet openings for cold and hot water. For purposes of operating the mixing valve in combination with thermally or hydraulically controlled flow heaters, the centroids of the port areas of the inlet openings, or at least the centroid of the port area of the cold water inlet opening, is shifted a few degrees of angle towards the cold water setting in order to achieve hydraulic asymmetry when the operating handle is in its central position.

Abstract: A sanitary mixing valve assembly, of the single handle type, which includes both a thermostatic control means to preset water temperature, and valving means to regulate volume flow between opened and closed positions, is disclosed. The thermostatic control means and valving means are arranged and constructed to form a unit within a replaceable cartridge.

Abstract: A damping means for controlling the closing action of a sanitary fitting to lengthen its closing time and, thereby, reduce its closing speed, is disclosed. The damping means is operatively mounted between the handle and valve control unit assemblies.
