<p>The machine comprises at least one displacement chamber disposed in a stationary housing and in the form of a spirally extending slot wherein strip or rib-like spiral housing walls of substantially uniform radial thickness are provided. Displacement members 3, 4 in the form of spiral-shaped strips or ribs of substantially uniform thickness and each associated with a respective displacement chamber are each held substantially at right angles on a disc-shaped rotor 1 which is drivable eccentrically relative to the housing. In order to increase the rigidity of shape of the strip or rib-like displacement members 3, 4 or of the housing walls, their radial thickness in the region of their circumferential ends 9 to 12 is increased. As shown the radial thickening is provided on a particular side of the displacement members or housing walls and is increased from value corresponding to the uniform section of the displacement members or housing walls, to approximately 1.1 to 2 times greater than that value. <IMAGE></p> |
