摘要： An apparatus comprising a movable temperature sensing member (39) capable of sensing mainly the temperature of high-temperature coolant flowing in from a high-temperature coolant port (33) and driving toward the side of the high-temperature coolant port (33) in dependence upon the sensed temperature; a main valve (36) fitted integrally to the movable temperature sensing member (39) and constructed so as to render a low-temperature coolant port (31) and a mixing compartment (32) openable in conformity to the driving of the movable temperature sensing member (39) toward the side of the high-temperature coolant port (33), thereby controlling the inflow rate of low-temperature coolant from the low-temperature coolant port (31) to the mixing compartment (32); and a high-temperature coolant inducing part (42) communicating with the high-temperature coolant port (33) and adapted to regulate the flow of high-temperature coolant from the high-temperature coolant port (33) toward the surround of the movable temperature sensing member (39) and effect outflow thereof to the mixing compartment (32).

摘要： Disclosed is a thermostat device which can both stabilise operation during the initial stages of valve opening, and can stabilise the temperature of a liquid coolant which is circulated in a cooling system circuit. A circular sealing lip (29) is provided on the outer periphery of an approach section (24) of a main valve (21), said approach section being to a cylindrical valve seat (11), and the circular sealing lip is elastically pressure welded to the inner peripheral surface of the cylindrical valve seat (11) when the valve is closed. The circular sealing lip (29) is provided so as to form a waveform having concavity and convexity curving in the drive direction of the main valve (21), due to a thermo-sensitive movable body (31). Thus, the contact position of the circular sealing lip with the inner peripheral surface of the cylindrical valve seat when the valve is closed can be displaced in the drive direction of the main valve according to the position in the circumferential direction of the circular sealing lip. Therefore, liquid coolant is made to flow in at a low flow amount during the initial stages of valve opening, the flow amount of the liquid coolant can be gradually increased as the main valve moves in the valve opening direction, and operation during the initial stages of valve opening can be stabilised.
