The invention relates to a temperature regulating/pressure relief valve employing a shaped memory alloy wire positioned under tension within the housing of the valve. The wire contracts upon an increase in temperature in the fluid passing through the valve thereby initially either closing or opening the valve, and subsequently loading a spring which maintains the valve closed or opened under a predetermined pressure.

A temperature regulating, pressure relief valve comprising a hollow interior housing, normally opened entrance and exits ports within said housing for allowing fluids to flow through the interior of said housing, a closure device for said entrance port, an assembly for sliding movement within the interior of said housing affixed to said entrance port closure device, mechanical springs for movement of said sliding assembly, a shaped memory alloy wire assembly comprising wires held in tension within said sliding assembly, said shaped memory alloy wires contracting upon temperature increases of said fluids and thereby causing sliding movement in one direction of said assembly and said closure device resulting in the closing of said entrance port and the compressing of said mechanical springs for maintaining pressure upon said entrance port closure device, and said shaped memory alloy wires relaxing upon temperature decreases of said fluids and thereby resulting in sliding movement in an opposite direction of said assembly and said closure device resulting in the opening of said entrance port and the opposite compressing of said mechanical springs for maintaining pressure against closing said entrance port.
