Abstract:
A fuel injection valve comprising;a) a body; b) an electromagnetic solenoid disposed in the inside of said body; c) a movable core movable in the axial direction and disposed in the inside of said electromagnetic solenoid; d) a needle valve fixedly secured to the distal end of said movable core, said needle valve disposed in the inside of said body such that said needle valve is movable in the axial direction; e) a fixed portion disposed at a given position in the inside of said body such that said movable core approaches said fixed portion at the time said needle valve in the valve is moved in the closing direction, and such that a gap is formed between said fixed portion and said movable core at the time when said valve is being closed; and f) squeezing means being operable such that when fuel which remains in the gap formed between said movable core and said fixed portion is pressurized in correspondence with the movement of said movable core toward the valve closing side, said flow of fuel is squeezed at a portion which defines a passage for the fuel extruded through said gap.
