ABSTRACT:
A simple, one-chamber housing, having a uniformly increasing chamber diameter, has a generally ball-shaped valving element therewithin, and opposite ends of the housing are ported to admit and discharge fluid into and from the chamber. The element is freely translatable within the chamber, being guided on a housing-traversing rod, between a valve seat at one end of the housing, and abutments adjacent the other end of the housing. A first spring biases the element away from the valve seat, and second, more powerful spring is restrainingly held at the other end of the housing, ready to overpower the first spring, and force the element onto the seat, to close off the discharge porting, when inordinately elevated-temperature fluid enters the housing. A temperature-responsive arrangement, at the other end of the housing, is operative to release the second spring, and an element-confronting piston to cause the piston to bottom the element in the seat and seal off the discharge porting, until the temperature of the fluid modulates. The rod, then, is used to reset the second spring to its restrained disposition.
