Abstract
A temperature responsive flow control valve has a plunger type actuator positioned in a fluid flow passageway between a valve head and an adjustable abutment member. The actuator includes a canister filled with a heat expansible material which expands upon heating to drive the actuator from the canister so as to engage the valve head and drive it out of seated engagement with a valve seat against the biasing force of a spring. The abutment member is axially adjustable toward and away from the valve seat to adjust the distance therebetween. By adjusting the distance between the abutment member and the valve seat the temperature at which the actuator expands to a sufficient degree to open the valve may be adjusted. A controlled leak through the valve is provided.
