  • Patent number: 5397053
    Abstract: A shape memory effect actuated diaphragmatic anti-scald valve, including a valve housing having a fluid flow path therethrough and including a pilot chamber. There is a first valve seat within the housing and a second valve seat within the housing and downstream from said first valve seat. A pilot valve is located within the chamber of the valve housing for preventing fluid flow through the chamber in which the pilot valve element is located when the SME valve is in its normal flow position and a first valve element is retained seated on the first valve seat by the pilot valve. There are means for controlling the open and closed positions of the pilot valve depending upon the temperature of the fluid flowing through the SME valve.
