Abstract
The valve body has an orifice that provides communication between a high-pressure side passage through which a cooling medium flows in and a low-pressure side passage through which the cooing medium flows out. Also, the valve is provided with a valve element that adjusts the volume of the cooling medium passing through this orifice, an operating rod that operates the valve element in the valve opening position, and a temperature-sensing drive section that drives this operating rod. On the upstream side of the orifice of the high-pressure side passage is disposed a support ring that constrains the ball-shaped valve element of the valve body.
