Abstract
An improved hydraulic apparatus is disclosed which may function as either a hydraulic pump or hydraulic motor. A port plate (18) is provided with a high pressure arcuate prot (82) which permits the full range of rotation of the port plate to be used in linearly adjusting the rate of fluid flow into the cylinders (22) of the cylinder block (20). The invention provides a maximum range of adjustability of the volume of fluid flow passing through the cylinders.
