Abstract:
1. A fluid apparatus comprising: a shaft disposed to be rotatable; a plurality of pistons disposed to be reciprocated; a housing for containing the shaft, the housing having a plurality of cylinder bores in which the pistons are disposed; a swash plate rotatable integrally with the shaft for reciprocating the pistons, the swash plate slanting with respect to a center axis of the shaft, wherein the swash plate has a slant center about which the swash plate pivots while slanting, and the slant center substantially corresponds to the center of gravity of the swash plate; a balancer that adjusts the slant center of the swash plate to a position substantially corresponding to the center of gravity of the swash plate, regardless of a slant angle of the swash plate with respect to the center axis of the shaft; a shoe disposed at a radial outside portion of the swash plate to pinch the swash plate while slidably contacting the swash plate, wherein: the balancer is provided in the first side of the circular plate and the arm is provided in the second side of the circular plate such that the arm and the balancer are located on opposite sides of the circular plate.
