A sliding vane machine with a cylindrical rotor (11) eccentrically placed in a housing, the rotor being rotatably mounted in the housing with its periphery in contact with the interior of the housing at one point and being provided with a number of vanes (13). The vanes are guided in grooves (12) in the rotor (11) for essentially radial movement and delimit, together with the rotor (11) and the housing (1), chambers (14) for transporting a medium from an inlet opening (15) to a delivery opening (16). The movement of each of the vanes (13) is guided by at least one guide (17, 18), which runs along a guide race (19) in the housing. The guide race (19) and/or the interior of the housing (1) has such a shape, that the radially distal end of each vane (13) follows the contour of the interior of the housing (1).
