摘要： A valve (15) includes a housing (20) with a valve seat (23) and a structure (24) fixedly disposed remote from the valve seat (23). A valve head (40) is provided to open and close the valve seat (23), such that fluid can flow when the valve seat (23) is open. An elastic system (60) is anchored on the structure (24) and coupled to the valve head (40), and includes a biasing element (70) and an elastic element (80) formed of memory metal alloy which contacts the fluid permitted to flow. The biasing element (70) and the elastic element (80) are configured to cooperatively move the valve head (40) toward a valve seat open position when a fluid temperature is below a lower limit, and to cooperatively move the valve head (40)toward a valve seat closed position in opposition to the biasing element when the fluid temperature is above an upper limit.
