Axial piston machine

A heat recovery system in a motor vehicle comprising an axial piston machine including:

• a housing having a vapor chamber, a cylinder chamber and a wobble-plate chamber;
• cylinders arranged annularly around a shaft in the cylinder chamber and having pistons arranged therein in a translationally movable manner;
• a valve disk connected to the shaft in a rotationally fixed manner and arranged in the vapor chamber;
• a wobble plate connected to one of the pistons via a cup and ball bearing and to the shaft in a rotationally fixed manner, the wobble plate being arranged in the wobble-plate chamber;
• wherein the housing has a steam-chamber housing part, a cylinder housing part, and a wobble-plate housing part connected to one another;
• wherein a cylinder sleeve having a radially protruding collar is provided in at least one cylinder, wherein the cylinder sleeve is retained via the collar in a cut-out in the cylinder housing part, which adjoins a parting plane between the vapor-chamber housing part and the cylinder housing part;
• and
• wherein the vapor chamber is closed off by a first cover, which is connected to the vapor-chamber housing part and which is designed as a shaped sheet-metal part.

• wherein the cup and ball bearing has a cut-out protruding radially outwards;
• wherein the cylinder sleeve has a cut-out, which is open towards a front side and in which the cut-out of the cup and ball bearing is guided in terms of a lock against rotation;
• and
• the cup and ball bearing has two sliding feet arranged adjacent to the cut-out of the cup and ball bearing and supported on a guide bushing.
