ABSTRACT:
An axial piston pump assembly includes a housing having first and second interconnected housing portions (12,14). A cylinder barrel (18) has an axis of rotation and is rotatably supported in the housing about the axis of rotation. The cylinder barrel (18) includes a plurality of pistons (22). The pistons (22) are reciprocally supported in the each of the piston cavities (20) for reciprocating movement parallel to the axis of rotation reacting with a cam surface (30) and causing the reciprocating movement of the pistons (22). The pistons (22) include a body portion (44) having a longitudinally extending central bore (46). One end of the bore (46) defines a fluid inlet (48) into the bore (46) and the other end defines a fluid outlet (51). The fluid inlet (48) includes a ball seat (50) and a ball member (52) seated therein and substantially over the fluid inlet (48), the ball member (52) engaging the cam surface (30).
