A displacement machine for compressible mediums exhibits several spiral-shaped conveying spaces, which are disposed in a stationary housing and which span a circumferential angle of approximately 360 DEG . The spiral-shaped displacement bodies, which are assigned to the conveying spaces and which span a circumferential angle of approximately 360 DEG , are held in such a manner on a disk-shaped rotor, driven off-centered with respect to the housing, that during service each of their points effects a circular movement defined by the circumferential walls of the conveying spaces. The predominant reach of both the spirals of the conveying spaces and the displacement bodies extends with a first curvature and their exit-sided end exhibits over an angular range ( alpha ) of 45 DEG a second curvature that is clearly smaller.
