  • Patent number: 6921032
    Abstract: The sprayer has, in the interior of the handle, a flow channel, in which the cylinder element is arranged. The piston is mounted in a freely displaceable manner in the cylinder element, and the cylinder element is open on the end side in the direction of the shut-off valve. The cylinder element and the piston bound, for example, an air-filled gas volume. If pressure surges occur when the shut-off valve is closed quickly, these pressure surges are damped by the piston moving in the direction of the cylinder bottom and compressing the gas in the gas volume in the process.

  • Patent number: 6837259
    Abstract: The invention relates to a fitting part, suitable for conducting water of different temperature from at least one mixing and proportioning element. The fitting part has at least three ducts, the first duct and the second duct each running from a lower opening arranged in the region of the lower end of the fitting part to an opening at the side on the fitting part, and the third duct running from a lower opening arranged in the region of the lower end of the fitting part to an upper opening arranged in the region of the upper end of the fitting part and having at least one branch with a lateral opening. The flow direction of the water through the third duct is defined individually for each fitting by suitable separate closing elements, so that a large number of different fittings can be produced using a small number of components. The invention also relates to a fitting with such a fitting part.

  • Patent number: 6830072
    Abstract: The invention relates to a fitting housing having an underside, a top side, lateral outer surfaces, a water outlet, a cutout for accommodating a mixing and/or metering cartridge, two supply channels, which lead from the underside to the cutout and through which, during use, the mixing and/or metering cartridge is fed hot and/or cold water, and at least one discharge channel, which leads from the cutout to the water outlet and through which, during use, water is led away from the mixing and/or metering cartridge. According to the invention, the fitting housing, at least over part of the height of the cutout, is in the shape of a polygon in cross section. The discharge channel has a first channel section which runs in the vertical direction in the region of one of the corners of the polygon. As a result of the shape according to the invention of the basic body, it is possible to reduce both the amount of material used and the dimensions of the basic body, while maintaining the same stability.

  • Publication number: 20040231725
    Abstract: A temperature measuring device and a flowrate measuring device are both connected to a regulating unit, thus enabling the mixing temperature of the mixing water flowing through a supply line and the flowrate to be determined. The regulating unit serves for controlling a mixing valve and a shut-off valve. At the end of the filling operation, the overall volume introduced into a container and input via a control apparatus has the likewise input desired temperature, the regulating unit continuously determines, based on the flowrate and the measured mixing temperature, since a starting time point, the actual heat quantity contained in a part volume which has already flowed out.

  • Patent number: 6789698
    Abstract: Device by means of which a supply container subjected to positive pressure is connected in a sealed manner to a consumer element with the aid of a sealing element, sealing in the direction of the surroundings taking place before an opening element opens the valve of the supply container. This is realized by a sealing element which, as measured in the longitudinal direction (L) from the base of the cutout, is wider than the opening element, and by an amount of play, which allows the sealing element to accommodate the full displacement.

  • Publication number: 20030196712
    Abstract: The invention relates to a control cartridge and to a fitting equipped therewith, for regulating the water flow at a water outlet of a fitting. The control cartridge comprises a first control element which is provided with passage holes and can be rotated about an axis, and a stationary, second control element which bears against the first control element and is provided with passage holes, and an actuating element, the first control element and the second control element being arranged in a cartridge housing. The actuating element is connected in a rotationally fixed manner to the first control element via a connection reaching through the cartridge housing. When in use, the cartridge housing can be connected fixedly to a first outlet part of the water outlet and is capable of holding a second outlet part which, when in use, is arranged downstream with respect to the first outlet part.

  • Patent number: 6631735
    Abstract: The sanitary fitting is intended for two different qualities of water and, for this purpose, has outlet connecting branches (20, 21) which are separate from one another and into which two channel systems (50, 56), which are routed separately from one another through a common fitting housing (1), open out. Each channel system (50, 56) is provided with a valve arrangement (53, 17), each valve arrangement being functionally separate from the other and of which the top valve arrangement (17), assigned to the channel system (56), has a closure body (41) which executes a lifting movement and of which the actuating element (44) forms the top termination of the sanitary fitting.
