Abstract
A sanitary mixer tap with thermostat control comprises a cold water inlet (1), a hot water inlet (2) and a mixed water outlet, and incorporates a fixed valve seat disc (3), a valve disc (4), a temperature control and regulation unit (5), a control and regulation piston (6), a temperature dependent regulating element (7), an actuating lever, and a control lever (8) connected to the actuating lever. The valve seat disc (3) has a cold water inlet opening (9) connecting with the cold water inlet (1) and a hot water inlet opening (10) connecting with the hot water inlet (2), and the valve disc has passages (11, 12) communicating with the cold water inlet opening (9) and the hot water inlet opening (10) of the valve seat disk (3). The temperature control and regulating unit (5) has cold and hot water inlet openings (13, 14) communicating with the passages (11, 12) in the valve disc (4), and also annular spaces (15, 16) for cold and hot water respectively. The control and regulating piston (6) can be set relative to the temperature control and regulating unit (5) in an initial temperature-determining position of temperature control, and can be controlled for temperature regulating purpose…
