    摘要: An axial plunger pump which does not need bellows by restricting fuel to a cylinder bore configuring a pump portion and by lubricating the other portion with oil. The high pressure fuel pump includes a plunger reciprocating according to a shaking movement of a swash plate, a cylinder block forming a pump chamber together with the plunger, and a sealing member provided between the plunger and a cylinder bore for sealing oil leaked from the pump chamber to a chamber surrounding the pump chamber, wherein oil in the oil chamber is supplied from the outside of the high pressure fuel pump.

    摘要: An axial plunger pump includes a shaft having a swash plate effecting swing motion and transmitting driving force from the outside, plungers reciprocate by the swing motion of the swash plate. A cylinder block has cylinders formed so as to open on the side of the swash plate, with the plungers inserted therein. Passages in the block supply refuel to the cylinders. A body combined with the cylinder block encloses the swash plate. Sealing members are arranged between the plungers and the cylinders on the swash plate side of the passages formed in the cylinder block for sealing gaps between the plungers and the cylinders, respectively.

    摘要: The drive part for converting the revolution movement to the wobble movement is composed of the shaft for transmitting the drive force from outside, the swash plate rotated by the shaft and the wobble plate for converting the revolution movement of the swash plate to the wobble movement. Plural pistons are reciprocated in responsive to the wobble movement of the wobble plate. The crank room containing the swash plate, the wobble plate and the piston is separated into the fuel room and the drive room by the bellows. The bearings for transmitting the drive force between the shaft in the drive room and the swash plate, and the bearing for transmitting the drive force between the swash plate and the wobble plate are placed inside the drive room in order to lubricate the bearings. By arranging plural pistons inside the fuel room, the fuel is forced to be taken in and discharged by the reciprocate movement of the individual pistons.
