ABSTRACT:
A fuel injection valve which is adapted to carry out fuel injection in a double-step manner such that lifting of the nozzle needle through the initial injection stroke causes contraction of a first nozzle spring and subsequent lifting of the nozzle needle through the main injection stroke causes contraction of a second nozzle spring as well as the first nozzle spring. A first adjusting threaded member threadedly engages the nozzle holder and accommodates a second movable spring seat, the second nozzle spring urging the former, and a second adjusting threaded member for adjusting the setting load of the second nozzle spring. The first adjusting threaded member is disposed in urging contact with the first nozzle spring for adjustment of its setting load through its rotative displacement, independently of adjustment of the setting load of the second nozzle spring which is made by the second adjusting threaded member. A shim is interposed between the second movable spring seat and a seating surface of the first adjusting threaded member, the thickness of which determines the initial insection lift and is adjusted in dependence on the relationship between the distance between the first movable spring seat in its seated position and the first adjusting threaded member, and the length of a predetermined portion of the second movable spring seat.
