ABSTRACT:
A thermostatic mixing valve is provided comprising a thermostat body arranged in an elongated housing and actuating an axially displaceable control member, which regulates the inlet areas for the warm and cold water. The control member cooperates with a sleeve member for regulating one of the inlet areas. The sleeve member is axially displaceable in the housing by the pressure from one of the liquids and this movement is limited by a stop ring. The end of the sleeve member remote from the control member cooperates with an axially displaceable closing sleeve regulating the outlet area of the mixed water. Pressure means actuated by an actuating lever acts upon the closing sleeve by pivoting said lever about an axle perpendicular to the housing. The mixed water temperature being regulated by rotating said lever, at which means being arranged to axially displace the thermostat body.
