Abstract
A pressure sensitive valve suitable for various fluid delivery applications is disclosed consisting of a hollow body having an inlet and valve seat which defines the outlet. A valve stem is disposed within the hollow body, the stem having a valve head adapted to cooperate with the valve seat to open and close the valve, and also having a twisted biasing element which responds to fluid pressure on the valve head by linear expansion. The valve is particularly suited for automotive and industrial fuel injection.
