Abstract (en)
[origin: WO9941499A1] A hydraulic rotating axial piston engine (1), having a housing (2), enclosing a rotatable cylinder barrel (11), having a number of axial cylinders (13a, 13b) with a number of reciprocating pistons (12). Said pistons being reciprocating between two defined end positions and cooperated with an angled plate (21) in order to obtain said reciprocating movement. The cylinders (13a, 13b) have ports (16) alternatingly acting as inlet and outlet ports and the housing has at least one inlet and outlet channel (5, 6), each having a kidney shaped port, facing towards said inlet and outlet ports of the cylinder barrel, communicating with a number of the ports at the barrel. The cylinder barrel (11) is rotatable relative to a first axis (10), which is inclined relative to a second axis (9) of an input/output shaft (8), the angled plate being 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 being 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.
