ABSTRACT:
A displacement machine for compressible mediums has several spiral-shaped conveying spaces (11a, 11b), which are disposed in a stationary housing lead from an inlet (12a, 12b), which lies radially on the outside, to an outlet (13), which lies radially on the inside. A displacement body, which is assigned to the conveying spaces has a disk (2) with spiral-shaped strips (3a, 3b) arranged perpendicularly on both sides. This displacement body, driven off-centered, is made of a magnesium alloy. During service, each of its points effects a circular movement defined by the circumferential walls of the conveying space. The ribs (45, 46) bordering the conveying spaces (11a, 11b) in the housing are made as one piece with the housing and the entire housing is made of the same or similar magnesium-based alloy as the displacement body (2, 3, 4, 5).
