摘要： Needles include a cylindrical outer needle that is brought into contact with and moved away from a nozzle body (113) to open and close an injection hole (1132) and an inner needle (112), slidably inserted in the outer needle (111), that is moved into and out of a sack-tip-portion space (171). When the inner needle (112) enters the sack-tip-portion space (171) and completely occupies the sack-tip-portion space (171), the fuel injection direction B is made downward relative to the injection-hole central axis C. Thus, it is possible to control the fuel injection direction B by controlling the amount of lift of the inner needle (112).

摘要： A fuel injection pump for an internal combustion engine has a shaft rotatable by the engine. The shaft is formed therein with a radial bore and an axial bore communicated therewith. Pumping plungers are slidably disposed in the radial bore to cooperate therewith to define a compression chamber and cyclically reciprocated to vary the volume of the compression chamber. An injection plunger is slidably disposed in the axial bore to divide the interior thereof into a first pressure chamber always communicated with the compression chamber and a second pressure chamber adapted to be communicated with a delivery port in a discharge stroke of the pump. The first and second pressure chambers are supplied with fuel in a suction stroke of the pump. The fuel in the second pressure chamber is discharged therefrom in the discharge stroke. A single solenoid valve is provided to control the fuel discharge timing and the quantity of fuel to be discharged from the pump.

摘要： At least one choked flow passage communicates between one side of the movable member and the other side of the movable member and limits an amount of fuel, which passes from the one side of the movable member to the other side of the movable member, when the movable member is moved by an urging force of a relief spring toward a valve element. A larger amount of fuel, which is larger than the amount of fuel that is passable through the at least one choked flow passage, flows from a first return flow passage to a second return flow passage, when the movable member is moved toward the other side, which is opposite from the valve element, against the urging force of the relief spring.

摘要： A fuel injection device wherein when the combined natural resonant period of a piezo stack and a driving member constituting part of a piezo injector of a fuel injection device is denoted by T, and the voltage rise time taken from the moment the charging to the piezo stack is initiated until the piezo stack is charged to a target charge voltage is denoted by t, then, in order to prevent oscillating loads from being applied to the piezo stack after elapse of the voltage rise time t when t≦0.5 T±0.1 T, the voltage rise time t that satisfies the relation 0.6T≦t is set in a controller for the piezo injector and, thus, the voltage rise slope of the piezo stack immediately before reaching the end of the voltage rise time t is made gentler to suppress the expansion and contraction force occurring in the piezo stack and thereby enhance the long-term reliability of the piezo stack.

摘要： A distributor type fuel injection pump has an accumulator. When an internal combustion engine is in low-speed rotation or in low-load operation, the accumulator accumulates part of the fuel pressurized within a fuel compression chamber, thereby lowering the fuel injection rate. Also, the fuel injection pump is provided with compensator which operates simultaneously with the accumulator. While the injection rate is lowered by operation of the accumulator, the compensator extends the injection period to compensate for the reduction of injection quantity attributed to reduction of the injection rate.
