Axial piston machine with high drive rotational speed

A swashplate-type axial piston machine comprising:

• a housing;
• a drive shaft supported on the housing rotatably about an axis of rotation by a first rotary bearing and a second rotary bearing;
• a cylinder drum accommodated in the housing, the cylinder drum surrounding the drive shaft, the cylinder drum including a rotational drive connection to the drive shaft, the cylinder drum arranged between the first rotary bearing and the second rotary bearing;
• a distributor plate arranged in a direction of the axis of rotation between the cylinder drum and a support surface on the housing, the distributor plate being arranged adjacent to the support surface and lying with a non-planar sliding surface, which is rotationally symmetrical with respect to the axis of rotation, against the cylinder drum such that the cylinder drum is held transversely with respect to the axis of rotation by the distributor plate;
• and
• at least one working channel that extends through the distributor plate,
• wherein each channel of the at least one working channel opens out at an outside on the housing at an associated working port,
• wherein the at least one working channel comprises a first section and a second section,
• wherein the first section extends over an entirety of the distributor plate,
• wherein the second section is arranged entirely in the housing,
• wherein the second section directly adjoins the first section,
• wherein the first rotary bearing has an outer circumferential surface that defines a circular cylindrical reference cylinder about the axis of rotation,
• wherein the first rotary bearing is arranged with a spacing to the distributor plate in the direction of the axis of rotation,
• wherein the distributor plate is held on the support surface transversely with respect to the axis of rotation,
• wherein the first section and the second section of the at least one working channel run parallel to the axis of rotation, and
• wherein the first section and the second section are arranged entirely within or are intersected by an extension of the reference cylinder that extends parallel to the direction of the axis of rotation.
