Abstract

PURPOSE:To prevent burning caused by fretting of piston even under low pressure, high rotation and quite low inclination angle of swash plate, by making bush groove properly in workable range while employing coarse and fine grindstones to apply plato-horning in the land section with shorter interval to enable intrusion of oil. CONSTITUTION:Spiral circumferential grooves 11 are made in a bush 3 then minute grooves 12 shallower than said grooves are made in the land section by means of a coarse grindstone and convex sections are worked by means of a finer grindstone. Even when the inclination angle of swash board is quite low and the piston stroke is short, oil will instrude into the sliding face of the land section to prevent fretting thus to prevent burning of piston.
