<p>The axial piston machine may be used as a hydraulic pump or hydraulic motor. A rotor of the piston machine includes an outer part (13) having a spherical inner surface (15) and an inner part (14) having a corresponding spherical outer surface (16). The inner part has a plurality of elongate grooves (25) defined therein to seat pistons (28) therein. A plurality of piston members (27) protrude into the pistons. A sleeve member (30) is disposed inside the inner part. The sleeve member has a plurality of openings (33, 34) defined therein that are connected to chambers in an alternating fashion. The sleeve member may be turned sideways to adjust the position of the inner part relative to the outer part to set the operational volume of the piston machine.</p> |
