Abstract

The needle valve is seated against the valve seat by the differential pressure of the fuel. Lifting of the needle valve is caused by transmitting a control pressure sufficient to overcome the differential pressure under the piston. This control pressure is delivered via the control member which selectively opens and closes the control line to the flow of pressure medium.
