Patent ID: 7866624

Claim:
A valve for controlling a cryogenic flow medium from a tank, said valve comprising: a valve body; a valve plate positioned within the valve body; a valve seat element positioned in the valve body adjacent to the valve plate and defining a flow channel therebetween; a spring mounted to the valve plate and the valve body, said spring having a spring bias that forces the valve plate against the valve seat to close the flow channel; and a heating element positioned proximate to the valve plate, wherein the heating element is heated for causing the heating element to expand and move the valve plate away from the valve seat against the bias of the spring to open the flow channel and allow the cryogenic medium to flow therethrough, wherein the valve is a cryo-valve associated with a cryogenic tank, said cryogenic tank including an insulating layer, said cryo-valve being position within the insulative layer so that only wires associated with the crvo-valve extend out of the insulative layer.
