Abstract
A hydraulic rotating axial piston engine has a housing enclosing a rotatable cylinder barrel. The cylinder barrel has a number of axial cylinders with a number of reciprocating pistons therein. The pistons reciprocate between two defined end positions and cooperate with an angled plate in order to obtain the reciprocating movement. The cylinders have ports alternatingly acting as inlet and outlet ports and the housing has at least one inlet and outlet channel. The channels each have a kidney-shaped port, facing towards the inlet and outlet ports of the cylinder barrel, and communicating with a number of the ports at the barrel. The cylinder barrel is rotatable relative to a first axis, which is inclined relative to a second axis of an input/output shaft. The angled plate is rotatable together with the input/output shaft around the second axis. The rotation of the cylinder barrel and the input/output shaft are synchronized by means of synchronizing means. The combination of the cylinders and pistons are an even number and the synchronizing means has a synchronizing torque which during the whole rotation of the cylinder barrel is directed in substantially one single direction.
