ABSTRACT:
A control valve assembly for a fuel injector includes a valve seat with fluid inlet and fluid outlet and a flat seating surface. A poppet valve has a concave end portion with knife edge for sealingly engaging the flat seating surface on the valve seat. The poppet valve is operated to close by a solenoid coil and is opened and maintained open by a return spring or a permanent magnet. Faster valve closing and faster valve opening is obtained.
