Abstract

A unit for a single-lever mixing valve, includes a fixed housing defining an upper region, and a bottom, inlet region. An inner sleeve is located within the fixed housing. A cage is located within the fixed housing and adjacent to the inner sleeve. The cage is rotatable and radially displaceable relative to the housing. A spindle is swively mounted obliquely inside the inner sleeve, and engages the cage. The spindle is actuated externally relative to the fixed housing. A plurality of flat, superposed washers are provided. Each washer has at least one opening therethrough. One of the washers is an inlet valve attached to the fixed housing. Another of the washers is a distributor, temperature valve attached to the cage. Another of the washers is a volume valve forming a shim fitted between the inlet valve and the temperature valve. The volume valve and the cage are together radially displaceable on the inlet valve relative to the fixed housing. The temperature valve and the volume valve are together radially displaceable relative to the inlet valve. The temperature valve and the cage are rotatable together relative to the volume valve.
