Abstract
An axial piston pump including a housing, a cylinder block, and a swash block. The cylinder block is rotatable within the housing about a vertical axis and includes an array of openings in the cylinder block distributed about the vertical axis and an array of pistons reciprocatably movable within the respective openings. The swash block is rotatable about an axis of rotation that is transverse to the vertical axis, and the degree of rotation is configured to control the extent of reciprocation of the pistons as the cylinder block rotates. The swash block has arc shape conical bearing surfaces tilted relative to the axis of rotation that are configured to guide movement of the swash block rotationally about the axis of rotation and prevent movement of the swash block axially along the axis of rotation.
