ABSTRACT:
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.
