Abstract: In a cylindrical casing, a temperature regulation system shifts a valve sleeve body axially between valve seats of the cold and hot water inlets and a flow control lever mounted on screw threads propels a valve seat body mounted as a piston within the casing and carrying one of the valve seats so as to vary the distance between the two valve seats between which the sleevelike valve body moves. The control rod of the temperature regulating system passes through the valve seat body to bear against a balance spring the other end of which is adjustable by a temperature setting grip that varies the compressive force on the spring, but an adjusting device is interposed between the control rod and the spring for slightly varying the effective rod length in accordance with the position of the flow-control lever so as to compensate for a tendency of the controlled temperature to shift from the preset value when the total flow is varied.
