Claims20
A rotatable piston assembly for a reciprocating piston type hydraulic machine, the rotatable piston assembly comprising:
- a rotatable piston configured for a controlled rotation and configured to reciprocate within a cylinder bore of the reciprocating piston type hydraulic machine along a cylinder bore axis of the cylinder bore, wherein
- the reciprocating piston type hydraulic machine is an axial piston machine comprising a rotating swash mechanism configured for variable displacement, a stationary cylinder block, and a rotatable shaft coupled to the rotating swash mechanism, and
- the rotating swash mechanism is a rotating wobble plate connected to a swash collar through a plurality of bearings, and the swash collar is connected to the rotatable shaft through a plurality of bearings.
A method for using an axial piston machine as at least one of a pump and a motor, the axial piston machine including a rotating swash mechanism configured for variable displacement, a stationary cylinder block, and a rotatable shaft coupled to the rotating swash mechanism, the method comprising:
- reciprocating a rotatable piston of a rotatable piston assembly including a double sided piston configuration in a cylinder bore of the stationary cylinder block of the axial piston machine;
- rotating the rotatable piston in the cylinder bore during reciprocation;
- and
- controlling rotation of the rotatable piston in the cylinder bore through a rotational control assembly, wherein rotation of the rotating swash mechanism is configured to rotate the rotational control assembly.
