Abstract (en)

[origin: WO2009012606A2] In a displacement machine of spiral design, the displacement body (2) has a disc (3) which carries a protruding displacement element (4, 5) on each side. The hub (11) of the disc (3) is mounted by means of a hub bearing (10) on an eccentric disc (9) which is part of a driven drive shaft (6). Said drive shaft (6) is mounted within a housing (1) by means of a first and second bearing (7, 8). By arranging these bearings in receptacles (48a, 48b) which project into the conveying chambers of the housing, said two bearings (7, 8) lie close to the eccentric disc (9). The drive shaft (6) extends through a wall (22) of the housing (1) and carries a drive disc (23) at its free end which lies outside the housing (1). In the region of this drive disc (23), the drive shaft (6) is supported by means of a third bearing (24) which is held in a supporting part (25) which protrudes away from the housing (1).
