ABSTRACT:
A thermal relief valve for a gas cylinder has a body with an inner wall defining a passageway for flow of fluid between inlet and outlet. A piston within the bore moves between a first position arresting flow from inlet to outlet, and a second position permitting flow from inlet to outlet. A restricting assembly for arresting movement of the piston towards the second position includes a thermal sensitive element of suitable eutectic material at the bore inner wall, with protrusions defining a first camming surface, and two or more restricting elements defining a second camming surface positioned to engage the first camming surface. The thermal sensitive element, at lower temperatures, maintains the second camming surface for engagement with the first camming surface, thereby to arrest movement of the piston, and, at higher temperatures, permits movement of the restricting elements into a position with the second camming surface spaced from engagement with the first camming surface, thereby to permit movement of the piston to release fluid.
