摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve in which a control valve element is accurately controlled to an intended intermediate displacement magnitude. SOLUTION: The fuel injection valve comprises the control valve element 8 displaced to control pressure in a pressure chamber 5 acting on a nozzle hole valve element 4, an actuator 17 for creating operating force for displacing the control valve element, and an elastic supporting means 22 for elastically supporting the control valve element against the operating force. The actuator can vary the operating force through control of a controlled variable. The elastic supporting means is displaced together with the control valve element with increasing operating force. When displaced to an intended intermediate displacement magnitude, the control valve element abuts an abutting member 23. Before its own displacement, the abutting member is pressed with a set pressing force by an elastic member 24 separate from the elastic supporting means in the opposite direction to the operating force.

摘要： PROBLEM TO BE SOLVED: To control a needle at three positions of zero-, intermediate- and full-lifting without needing complicated control of a control valve. SOLUTION: A control room 2 acting on a needle 1 in a valve closing direction is communicated with a valve chamber 31 of a control valve 3 through the first and second out-orifices 22 and 24. The first out-orifice 22 is closed by the needle 1 or an intermediate lifting control piston 6 lifted integrally with the needle 1 when it goes over an intermediate lifting amount. When a valve element 32 is fully opened to open a low pressure port 33 and to close the second out-orifice 24, the low pressure port 33 is communicated with the first orifice 22 to lift the needle 1, and when over the intermediate-lifting position, the first orifice 22 is closed to hold the intermediate amount. Further, when the valve element 32 is half-opened and the first and second orifices 22 and 24 are both opened, the needle 1 is continuously lifted even after the intermediate amount to reach the full-lifting position.

摘要： PROBLEM TO BE SOLVED: To widen the control voltage width of an actuator for holding a valve element at a definite intermediate position in a system which controls the back pressure of a nozzle needle by a control valve and also controls the lifting amount of the control valve at three positions of fully closing, intermediate and fully opening. SOLUTION: A first control room 2 acting downward on a needle 1 and a second control room 4 acting downward on a lift lock piston 6 for defining the lifting amount of the needle 1 are both communicated with the valve chamber 31 of the control valve 3 through the first and second out-orifices 22 and 42. Further, a small diameter piston 54 for driving a valve element 32 is composed of a piston body 54a and its outer peripheral magnification-converting ring 54b. When the ring 54b abuts on a step part 55 at an intermediate position, the piston body 54a and the valve element 32 are held at the intermediate position until the area of a displacement enlarging chamber 53 receiving an oil pressure changes to sufficiently elevate the actuator voltage. Thereby, the control voltage width is widened and intermediate lift control performance is obtained favorably.

摘要： PROBLEM TO BE SOLVED: To minimize a spreading amount of a piezo stack required for opening valve and to miniaturize the device by eliminating requirement for changing a spring according to common rail setting pressure and uniforming increase amount of pressure in a control chamber required for opening valve. SOLUTION: A back pressure chamber 6 is faced to the upper end surface 2c of a displacement extending piston 2 sliding integrally with a needle 3 for opening or closing an injection hole to guide common rail pressure, and the common rail pressure is balanced with a fuel pressure applied to the lower end surface 2b of the displacement extending piston 2 and a fuel pressure applied to the needle 3. Thus, the needle 2 is applied only with an energizing force in the valve closing direction of the spring 13, so that the device can be operated by a constant spring force independently of the common rail pressure. The back pressure chamber 6 is communicated with an accumulating chamber 11 for accumulating fuel supplied to the injection hole 33, so that fuel in the back pressure chamber 6 is speedily discharged in opening the valve, pressure increase is suppressed, and the needle 2 is speedily lifted.

摘要： PROBLEM TO BE SOLVED: To control an injection pressure to a target value by relieving fuel to a high pressure pump side by utilizing a reverse flow phenomenon during closing of a check valve wherein a flow rate during lifting is further increased during a forward flow than during a reverse flow. SOLUTION: In a fuel injection device having a pressure accumulating piping 2 used for an internal combustion engine, a check valve 8 is arranged at the delivery port of the high pressure pump 1 of a fuel injection device. By utilizing the reverse flow phenomenon of a check valve 8 wherein a flow rate during lift is further increased during a forward flow than during a reverse flow, fuel is relieved to the high pressure pump 1 side. Since a flow rate factor when the check valve 8 is lifted like the above is further increased during a forward flow than during reversing, by applying a reverse pressure after a positive pressure enough for slight lifting of the check valve 8 is applied, a total flow rate is reduced to a minus, whereby pressure reduction control is practicable.
