Abstract:
A thermostat device, which comprises:a heat expansion element which is expandable and shrinkable upon sensing a temperature change of a circulating fluid in a circulation channel embedded in a case member;a sliding member:a thermo-element for causing sliding movement of said sliding member in accordance with expansion and shrinkage of the heat expansion element, said sliding member comprisesa first valve element rotatably supported by a valve shaft in the circulation channel, and controlling a flow rate of the circulating fluid by rotation of the valve shaft in accordance with sliding of the thermo-element in order to open or close said valve shaft,said sliding member being disposed outside the circulation channel of the circulating fluid, anda bottom bypass structure in communication with said circulation channel and having a bypass channel for said circulating fluid, said bypass channel being located downstream of said valve element so as to open or close said circulation channel to thereby bypass the circulation fluid to one side of the valve for heat exchange.
