Patent abstract
A fluid control thermostatic valve contains thermally responsive wax. As temperature rises, the wax expands thus pushing a deformable member up a confined path defined by guide 40 until the member contacts a fixed post 60. An immobile retainer 72 is secured to the fixed post 60. Force from the elastic member against the post causes actuator 30 to separate from retainer 72, thus opening a flow passage. The control valve is unique because retainer 72 functions as both a valve seat for actuator 30 and a fixed support for spring 84.
