A hydraulic rotating axial piston engine, having a housing, enclosing a rotatable cylinder barrel, having a number of axial cylinders with a number of reciprocating pistons, said pistons reciprocating between two defined end positions. The pistons cooperate with a plate angled relative to a rotational axis (10) for the barrel in order to obtain said reciprocating movement. The cylinders have ports alternatingly acting as inlet and outlet ports. The housing has an inlet and an outlet channel, each having a kidney shaped port (28, 29), facing towards said ports of said cylinders and communicating with a number of said ports. The housing has two parts, one part of the housing parts defining the turning positions of the barrel in the end positions of the pistons. A second part (4) of the housing parts defines the turning positions of the kidney shaped ports, relative to the end positions. The first and second parts of the housing is alternatively positionable in two different turning positions in order to choose rotational direction of the cylinder barrel. The two turning positions are two different positions deviating from a relative turning angle of 0 DEG alternatively 180 DEG so that the kidney shaped ports (28, 29) are displaced a predetermined extent in the rotational direction. |
