Abstract
In a hydraulic axial piston machine, which may be a pump or hydraulic motor, whose cylinders are located on a larger circle than the cylinder ports and the stationary high pressure and low pressure ports of a stationary body, a tilting moment is exerted on the cylinder block which is compensated by radial pressure exerted on the cylinder block by positioning cylinder and piston members operated either directly by high pressure fluid from the high pressure conduit of the stationary body, or indirectly under the control of a valve operated by leakage fluid obtained from a recess in the control face of the stationary body.
