ROTATING SPIRAL COMPRESSOR WITH REINFORCED SPIRAL RIBS

摘要

A rotating sprial charger for compressible media is disclosed having a housing in which two symmetrically constructed displacer disks are located and rotated by drive elements. The two displacer disks are provided on one side with helical ribs. To form a conveying space, the ribs engage each other and seal with their free frontal sides against the opposing displacer disk. To increase the strength of the ribs, a reinforcement is provided on the outer periphery of the ribs. The reinforcement is located on the outer wall of the rib and extends over the entire axial length of the ribs. The reinforcement also extends in the peripheral direction from the end of each rib on the inlet side to the end on the inlet side of the rib following in the peripheral direction.
