Fluid-Maschine

摘要

There is disclosed a hydraulic or pneumatic machine having a first displacement element (8) that is rotatable about an axis of rotation, connected to a shaft (10) so as to rotate therewith, which shaft is mounted rotatably in a housing (2), and co-operates with a second displacement element (9), the axis of rotation being arranged at a predetermined distance from the centre axis of the second displacement element (9). The structure of such a machine is to be improved. For that purpose, the housing (2) has a pocket (3) in which the displacement elements (8, 9) are so arranged that the housing (2) covers the displacement elements (8, 9) axially on both sides (4, 5) at least in a working region and in the circumferential direction over a maximum of 180 DEG .
