A control thermostat (1) is connected to a liquid cooling system of an internal combustion engine. The control thermostat (1) has an inlet side housing (11), an outlet side housing (10), both the housing being communicated with each other to form a valve passage therein, a thermo-actuator (2) provided in the valve passage, a valve (17) operated by the thermo-actuator (2). The inlet side housing (11) and the outlet side housing (10) are communicated with coolant passages of the liquid cooling system so that a part of the coolant in the cooling system flows from the inlet side housing (11) to the outlet side housing (10) passing through the valve passage. The thermo-actuator (2) is arranged so as to close the valve (17) when the coolant temperature is higher than a predetermined temperature. A jacket (41) is provided for transmitting heat of the coolant discharged from the outlet side housing (10) to an element of the internal combustion engine, whereby controlling temperature of the element to a constant value. <IMAGE> |
