摘要： An axial piston machine includes a housing, a drive shaft, and a cylinder drum. The drive shaft is mounted in the housing so as to be rotatable with respect to a first axis of rotation. The cylinder drum is mounted so as to be rotatable with respect to a second axis of rotation. The cylinder drum has at least one cylinder bore that linearly guides an elongate piston. The piston has a first end connected to the drive shaft by a ball joint and a section in the form of a circular cone which tapers toward the first end. The piston also has a spherical section at the second end that is situated opposite the first end. The cone-shaped section merges without offsets and kinks into the spherical section. The piston has a flat end face at the second end which defines a plane that intersects the spherical section.

摘要： An axial piston engine, in particular pump or motor, includes a housing, a drive shaft, and a cylinder drum. The drive shaft is mounted in the housing so as to be rotatable with respect to a first axis of rotation. A bearing body is received in the cylinder drum rotatably with respect to a second axis of rotation. The bearing body is connected to the drive shaft via a first ball joint that has a joint center lying on the first axis of rotation. The cylinder drum has at least one circular-cylindrical cylinder bore in which an elongated piston is displaceably received. A first end of the piston is connected to the drive shaft via a second ball joint. The at least one cylinder bore is arranged at an inclination to the second axis of rotation.
