Abstract: A mixing valve has a housing, a fixed valve plate in the housing having a flat outer surface generally centered on and perpendicular to a main axis and formed offset from the main axis with a pair of angularly offset and axially throughgoing inlet ports, and a movable valve plate in the housing having an inner surface flatly engaging the outer surface of the fixed valve plate and an opposite outer surface. The movable valve plate is formed with a pair of angularly offset and axially throughgoing inlet ports alignable with the fixed-plate inlet ports. The ports of one of the pairs of inlet ports are at different radial spacings from a center of the respective plate.
Abstract: A valve assembly has a valve housing formed with a bore open at a surface and extending along an axis, an inlet passage opening into the bore, inner and outer outlet passages also opening into the bore, and an inner valve seat between the inlet passage and the inner outlet passage. A sleeve fitted in the bore forms an outer valve seat between the inlet passage and the outer outlet passage and a valve body is displaceable in the bore between an inner position against the inner seat and blocking flow from the inlet passage to the inner outlet passage and an outer position against the outer seat and blocking flow from the inlet passage to the outer outlet passage. A retaining disk fitted in the bore between the outer surface and the sleeve secures the sleeve in the bore. A stem extending through the sleeve and through the disk has an inner end connected to the valve body and an outer end outside the valve housing. Seals are provided between the sleeve and the stem.
Abstract: A valve cartridge has a hollow housing having an open end, a floor plate closing the open end and formed with a plurality of throughgoing ports each having an inner surface, a valve plate in the housing fixed atop the floor plate and formed with holes aligned with the floor-plate ports, a movable valve plate in the housing atop the fixed valve plate and formed with a cavity, and an actuating element connected to the movable valve plate for displacing the movable valve plate on the fixed plate and shifting the cavity into and out of engagement with the fixed-plate holes so that if one of the holes is supplied with water under pressure the actuating element can control flow from the one hole to the other hole. Respective annular seal rings made of an elastomeric plastic are received in the ports, formed in situ in the ports, and have outer surfaces bonded to the inner surfaces of the respective ports. The floor plate is made of a material that can bond to and slide relative to the plastic of the seal rings.
Abstract: A water valve has a fixed valve housing, a knob pivotal on the housing about a knob axis and formed with a radially throughgoing aperture, and an abutment projecting radially from the housing. The aperture passes the abutment on rotation of the knob on the housing about the knob axis. A pivot on the knob defines a rocker axis adjacent the aperture and substantially parallel to but offset from the knob axis. A rocker pivotal on the pivot about the rocker axis has an end displaceable radially through the aperture between an inner position engageable with the abutment on movement of the window past the abutment and a position not engageable with the abutment on such movement. A spring braced between the rocker and the knob urges the rocker into the inner position.
