ABSTRACT:
In a sanitary single-lever mixer valve, the linear displacement of a movable plate cam, which can carry out a combined rotary and linear movement upon a fixed plate cam arranged in a housing, is influenced by an elastic locking device. This acts in the region of two co-operating guide surfaces, of which one is provided on an element rotatably guided in the housing and the other is provided on the movable plate cam. A first opening is provided in a first of these guide surfaces. A second opening is provided in the second of these guide surfaces, has an approximately circular cross section, is intersected by the guide surface and receives a spring element. The latter is constructed as an incompletely closed hollow moulded element which attempts to expand elastically within the opening and therefore always projects as far as possible beyond the associated guide surface. However, the spring element can be forced completely into the accommodating opening under elastic compression.
