Abstract
A hydraulic machine is provided comprising a cylinder unit () having a plurality of cylinders () which are located on a circle line around an axis of rotation of said cylinder unit (), a valve plate () located at an axial end of said cylinder unit () and having a through-going opening () for each cylinder (), and a port plate, said valve plate () and said port plate resting against each other in sliding contact at a contact face, wherein a pressure in each cylinder () acts on a pressure area on a side of said valve plate () opposite said port plate. In such a hydraulic machine the risk of leaking should be kept small. To this end said pressure area () deviates from a circular form.
