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.

Abstract: An extremely compact, simple and reliable thermostatically control valve for mixing two fluids of different temperatures comprises means for manual adjustment of volume and temperature of the mixed fluids leaving the valve, wherein said adjustment means are disposed for setting a temperature sensible member adapted to control by means of its thermal expansion the position of a control member which in turn controls the volumes of the different fluids in order to maintain the mixed fluid at the temperature set, the supply of one of said fluids being arranged through a pipe extending through said control member and opening in a first chamber communicating with a second chamber wherein said temperature sensitive member is disposed, said fluids being mixed in either of said first or second chambers, and said second chamber being provided with a further communication duct communicating with the outlet of the valve.
