ABSTRACT:
A drive part for converting rotational movement in a fuel pump to the wobble movement includes the shaft for transmitting an outside drive force, the swash plate rotated by the shaft and the wobble plate for converting the rotational movement of the swash plate to the wobble movement. Plural pistons are reciprocated in response to the wobble movement of the wobble plate. The crank room containing the swash plate, the wobble plate and the piston are separated into the fuel room and the drive room by 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 reciprocating movement of the individual pistons.
