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. An actuating lever is displaceable in the housing about the main axis and about a transverse axis crossing the main axis for shifting the movable plate between a closed position with both of the movable-plate inlet ports out of alignment with the fixed-plate inlet ports and blocked by the fixed-plate outer face, a pair of end positions with one of the movable-plate inlet ports aligned with one of the fixed-plate inlet ports and the other of the movable-plate inlet ports out of alignment with the other of the fixed-plate inlet ports, and an intermediate position with each of the movable-plate inlet ports partially overlapping the respective fixed-plate inlet port.
