Title: Axial piston pump
Inventor: TANI NOBUYUKI
IPC: F04B53/00
Filed: 1991-12-27
Abstract: PURPOSE:To provide an axial piston pump causing low noises. CONSTITUTION:A plain bearing is used for a bearing 5 supporting a rotary shaft 3. A cylinder block 8 fitted through spline on the rotary shaft 3 is supported by a plain bearing 11 consisting of an inner ring 9 press fitted in the outer peripheral part of the cylinder block 8 and an outer ring 10 press fitted in the inner peripheral part of a casing 1. A first path 20, second paths 28, 29 and a third path 32 are provided respectively in a retainer guide 19, the rotary shaft 3 and a valve plate 21. The plain bearings 5, 11 do not cause mechanical impact sounds. Since no radial load is applied to the spline fitted part of the cylinder block 8, the impact sounds caused by the collision of teeth with each other do not take place. Since working oil is supplied through the first, second and third paths to the suction side of the valve plate 21, pressure loss on the suction side is reduced to reduce noises caused by cavitation.
