PROBLEM TO BE SOLVED: To make up a thermostat valve for refrigerant circulation of an internal combustion engine, having an actuating member of an electrically heatable thermal responsing movability so that it hardly depends on the constructive shape of a housing. SOLUTION: This thermostat valve is provided with a housing (11) for an actuating member (10) of the thermally actuated properties of which the piston (12) is made to operate a valve member (13) and a support (25) for a return spring (24) for encouraging a valve member (13) on a base plate (17).
