Abstract:
A hydraulic rotating axial piston engine comprising:a housing enclosing a rotatable cylinder barrel, the cylinder barrel having a number of axial cylinders with a number of reciprocating pistons, with the pistons reciprocating between two defined end positions and cooperating with an angled plate in order to obtain the reciprocating movement, said cylinders having ports alternatingly acting as inlet and outlet ports, said housing having at least one inlet and outlet channel, each channel having a kidney shaped port, facing towards said inlet and outlet ports of said cylinder barrel, and communicating with a number of said ports at said barrel, said cylinder barrel being rotatable relative to a first axis, said first axis inclined relative to a second axis of an input/output shaft, said housing having at least two parts, one part of said housing positioning the input/output shaft and a second part including said kidney shaped ports, said angled plate being rotatable together with said input/output shaft around said second axis, the rotation of said cylinder barrel and said input/output shaft being synchronized by means of synchronizing means, a central support pin extending along said first axis between said angled plate and said cylinder barrel, said support pin at one end axially connected with said angled plate and in the other end axially connected to said cylinder barrel, said support pin limiting axial movement of the cylinder barrel relative to the angled plate, but allowing rotation of the cylinder barrel relative to the angled plate.
