<p>A rotary scroll supercharger for compressible media consists essentially of a housing (1) in which two symmetrically constructed displacement discs (6,7) are arranged in such a way as to be rotatable by means of drive elements (18-23). The two displacement discs are each provided on one side with spirally extending ribs (14). To form a delivery chamber (15), the ribs interengage and, with their free end faces (24), provide a seal relative to the opposite displacement disc. …<??>In order to increase the strength of the ribs, they are provided on the outer periphery with a reinforcement (32,32'), which is provided on the outer wall of the ribs, extends over the entire axial length of the ribs and extends in the circumferential direction from the inlet end of each rib to the inlet end of the next rib in the circumferential direction. …<IMAGE>… </p> |
