摘要

The piston machine (10) has housing (12) that is provided with a conveying element (24). The conveying element is rotatably mounted in an annular bearing (30). The annular bearing with backlash is secured at the housing by an anti-rotation element (16). The ring bearing and anti-rotation element are connected with one another to form an individual component (46).
