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.
