Claim Text:
1. A vane cell machine comprising: a hollow stator, a rotor disposed within the hollow stator, radially displaceable vanes arranged in guides at a radially outward surface of said rotor, two side walls, each side wall at an axial end of the rotor and including a plate that has a central bore that is substantially coextensive with a side section of the rotor, and two inserts, each insert fitted into the central bore of a corresponding one of the two side walls and each insert defining a bore that is eccentric to the central bore of the corresponding side wall, the bores of the two inserts being coaxial with the rotor, wherein said rotor at its axial sides bears substantially only against the inserts, wherein said vanes bear at their radially outward edges on an inside of the stator and bear at their axial sides substantially only against the plates, wherein said vanes, together with the rotor, the stator and the two side walls at each axial end of the rotor, border work chambers, wherein each insert is axially movable in relation to the rest of the corresponding side wall plate, and wherein each insert has a first pressure application surface on an axial inside surface facing the work chambers and the rotor and a second pressure application surface on an axial outside surface facing away from the work chambers.
