<p>A hydraulic rotating axial piston engine (1), having a housing, enclosing a cylinder barrel (111) journalled in said housing for rotation around a barrel axis and having a number of circumferentially arranged cylinders (113b) with a number of pistons reciprocating between two defined end positions. The pistons cooperate with an angled plate in order to obtain said reciprocating movement. The axial piston engine has an input/output shaft, and the cylinder barrel has channels (115b) connecting each cylinder to ports (116b) in the cylinder barrel which ports alternatively act as inlet and outlet ports. The housing has an inlet and outlet channel, each having a kidney-shaped port, facing towards said inlet and outlet ports of said cylinder barrel. The kidney-shaped ports communicate with a number of the ports at the barrel. The cylinder barrel ports extend in both directions outside the cylinders in the two circumferential directions of the cylinder barrel. The channels (115b) open to the cylinders (113b) along the peripheral wall of each cylinder and the opening (150) to the cylinders has substantially the same area as the area of the ports (116b) of the barrel (11/111).</p> |
