Abstract
A thermostat-regulated sanitary mixing tap has a cold water inlet (1), a hot water inlet (2), a mixed water outlet, a temperature control and regulation block (5), a control and regulation piston (6), temperature-dependent regulating means (7) which cooperate with the control and regulation piston (6), an actuating lever, restoring spring means (35) which bias the control and regulation piston (6) in the direction of the regulating means (7), a cold water ring-shaped chamber (15) and an adjacent hot water ring-shaped chamber (16). To control the temperature, the control and regulation piston (6) may be set at an initial position with respect to the temperature control and regulation block (5), in order to determine the initial temperature, and may be controlled by the regulating means (7) in order to regulate the temperature. In order to prevent the temperature of the mixed water from being affected by any leakage currents from the cold water (15) and/or hot water (16) ring-shaped chambers and to achieve a control and/or regulation which is as free as possible from such influences, at least one ring-shaped sealing membrane (16) provided between the temperature control and regulatio…
