摘要： A fuel injection device for internal combustion engines includes a needle valve (3) for opening and closing an injection port (33), a control chamber (5) for applying a fuel pressure to the needle valve (3) in a needle valve opening direction, a spring (13) for applying a biasing force to the needle valve (3) in a needle valve closing direction, a piezoelectric actuator (4) for increasing and decreasing a fuel pressure in the control chamber(5), a piston (2) which slides with the needle valve (3) so as to receive the fuel pressure in the control chamber (5) at a lower end face (2b) thereof, and a pressure storage chamber (11) for storing a fuel to be supplied to the injection port (33). The fuel injection device further includes another control chamber (6) which communicates with a fuel supply line (17) for applying a fuel pressure to an upper end face (2c) of the piston (2) in a needle valve closing direction. The another control chamber (6) communicates with the pressure storage chamber (11) via communication means (22).

摘要： A fuel injection valve (1) provided with a control valve (8) which is displaced in order to control a pressure within a pressure chamber (5) acting upon a jet hole valve (4), an actuator (17) which generates an operation force for displacing the control valve (8), and elastic support means (22) which elastically supports the control valve in resistance to the operation force. The actuator (17) can change the operation force by controlling a control amount, and the elastic support means (22) is displaced along with the control valve (8) in accordance with increase of the operation force. When the control valve (8) is displaced to a chosen intermediate position it abuts with an abutting member (23). This abutting member (23) is pushed by a set pushing force, generated by a elastic member (24) which is separate from the elastic support means (23), which acts in the opposite direction to the operation force prior to the displacement of the abutting member (23). By structuring the fuel injection valve (1) in this way, it is possible to accurately control the control valve (8) such that it has the chosen intermediate displacement.
