Abstract

PURPOSE: To improve self absorbing capacity by a method wherein a retainer is connected to a swash plate through a ball-and-roller bearing to give force for pulling pistons positively from the swash plate.
CONSTITUTION: The spherical seat of a shoe 9 is inserted into the holes 16 of the retainer 15, the upper surface of the shoe 9 is pushed by the retainer 15, deep grooves having a semicircular arc section are provided between the external peripheral surface of the retainer 15 and the internal peripheral surface of the external cylinder 18 inserted in the swash plate 11 and rollers 17 are inserted between these deep grooves to provide a ball-and-roller bearing. In the suction process the shoe 9 is pulled positively by the retainer 15, the rollers 17, the external cylinder 18, the swash plate 11 in such order, each piston 8 is drawn out of a cylinder block and oil is absorbed from the suction port 20 through a value plate 19.
