Abstract
A hydraulic machine having a housing, a cylinder block located in the housing and having axial pistons slidably movable in cylinders, a shaft rotationally connected to the cylinder block, and a swash plate in load engagement with the pistons of the cylinder block. The swash plate is pivotally mounted in the housing by at least one bearing, such that said swash plate is pivotally adjustable about a kinematic axis to alter a hydraulic displacement of the pistons in the cylinder block. The thrust pistons are located between the swash plate and the housing so as to urge the swash plate toward the cylinder block.
