    摘要: A cylinder is configured into a bottomed tubular form and includes an inner peripheral wall, an inner bottom wall, an outer peripheral wall and an intake hole and a discharge hole. The inner peripheral wall slidably guides the plunger. The intake hole and the discharge hole communicate between the inner peripheral wall and the outer peripheral wall. A pump housing includes a cylinder receiving hole that includes an inner peripheral wall, into which the cylinder is inserted. A pressurizing chamber is formed by the inner peripheral wall and the inner bottom wall of the cylinder and a distal end outer wall of the plunger.

    摘要: A plunger stopper is installed to a cylinder hole forming portion of a cylinder forming member. The plunger stopper cooperates with a step portion of a plunger to limit movement of the plunger in a state where a slide surface of the plunger contacts an inner peripheral wall surface of the cylinder hole.

    摘要: A gas chamber is placed adjacent to a variable volume chamber of a high pressure pump. The gas chamber includes an inner blocking wall, which borders on the variable volume chamber and contacts fuel in the variable volume chamber, an outer blocking wall, which is opposed to the inner blocking wall, and gas, which fills a space that is defined between the inner blocking wall and the outer blocking wall.

    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.
