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.

Abstract: The valve upper part has a head piece (1), a spindle (2) and a valve piston (3). The valve piston (3) can move axially in the head piece (1). The spindle (2) can rotate in the head piece (1). Spindle (2) and valve piston (3) are connected together via a movement thread (24, 32). The movement of the valve piston (3) in the axial direction is limited by a stop arranged internally on the head piece (1) and arranged externally on the spindle (2) in the same cross-sectional plane. For axial location, the valve piston (3) and the head piece (1) each have a polyhedron (31; 14) which is formed by teeth which are triangular in cross-section and which interlink. When the valve piston (3) is closed the sealing is hydrostatic by means of a sealing ring (42) retained in the head piece (1).

Abstract: An axially movable valve piston (3) and a rotatable spindle (2), which are connected with one another via a thread (24; 32), are guided in a headpiece (1). A sealing ring (5), which projects beyond the end face of the headpiece (1) facing the suppy duct, is held by the headpiece (1). The sealing ring (5) is designed on the projecting outer end face as a surface (54) for resting against a valve seat (62) and on the opposite inner end face as a lip seal (52) cooperating with the valve piston (3). In its section cooperating with the lip seal (52), the valve piston (3) is designed in a flat and seal-free manner.

Abstract: A valve seal having a profiled ring of a rubber elastic material, and an externally threaded supporting ring which is disposed about and vulcanized to the ring. The external portion of the supporting ring projects outwardly beyond the external surface of the profiled ring.
