Swash plate axial piston pump with pulsation damping means

摘要

At least two passages(24) with associated outlet holes(27) are formed in a connecting plate(17) and also in the web(26) in the cam plate dividing the LP kidney slot from the HP kidney slot and connect a reversing capacity(23) to the piston bores(11) passing through the web. The outlet holes of the passages corresponding to the piston bores are located on the reference circle formed by the LP(19) and the HP(18) kidney slots. The outlet holes and the passages may have the same or different diameters.
