초록 ▼

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.

대표청구항 ▼

A fluid pressure control valve assembly for a fuel injector comprising: a valve body with fluid inlet and fluid outlet ports; a valve seat communicating with said fluid inlet and said fluid outlet ports, said valve seat having a flat seating surface; a poppet valve slidably mounted in said valve body with one poppet end portion sealingly engagable with said valve seat flat seating surface to block said fluid inlet; an electrical actuator adapted for mounting at the other poppet end portion and operably energized for moving said poppet valve into said sealing engagement with said valve seat; return means coupled to said poppet valve to disengage said poppet valve from said valve seat; and said one poppet end portion having a concave end portion for sealingly engaging said flat seating surface of said valve seat. An electronically-controlled fuel injector system comprising: an injector body having a fuel inlet and a fuel outlet; a fuel injection pumping assembly, including a nozzle receiving fuel from said fuel inlet for injecting said fuel under pressure from said pumping assembly; a pressure control valve assembly for controlling the injecting of said fuel, said control valve assembly including a valve seat having a valve seat inlet connected to said injector body fuel outlet and having a drain fuel outlet, said control valve assembly including, a poppet valve slidably mounted in said valve body with one poppet end portion sealingly engagable with said valve seat flat seating surface to block said valve seat inlet; said one poppet end portion having a concave end portion for sealingly engaging said flat seating surface of said valve seat; an electrical actuator adapted for mounting at the other poppet end portion and operably energized for moving said poppet valve into said sealing engagement with said valve seat; and return means coupled to said poppet valve to disengage said poppet valve from said valve seat.
