ABSTRACT:
A fluid valve for controlling a high pressure fluid including a non-resilient valve seat with a flat seating surface. A non-resilient valve member has a concave end with an annular knife edge to sealingly engage the flat seating surface. A barrel slidably guides the valve member in movements with respect to the valve seat and forms a fluid chamber with the valve seat. The valve seat includes passageways between a high pressure valve inlet and the fluid chamber and between the fluid chamber and a valve outlet. An electrical actuator is operably energized to move the valve member into sealing engagement with the valve seat and return means disengage the valve member from the valve seat. The electrical actuator and valve member are part of an electronically-controlled fuel injector system with an injector body, a fuel injection pumping assembly with a nozzle receiving fuel from a fuel inlet to inject the fuel under pressure, and a pressure control valve assembly for controlling the fuel injection.
