ABSTRACT:
A rotating helical charger for compressible media consists essentially of a housing (1), in which two symmetrically constructed displacement disk (6, 7) are rotated by drive elements (18-23). The two displacement disks are equipped on one side with helical ribs (14). To form a conveying space (15), the ribs engage each other and seal with their free frontal sides (24) against the opposing displacement disk. To maintain the sealing effect, a pressure chamber (26) is provided, which communicates with the outlet (16) of the charger and may be acted upon by an axially displaceable annular disk (28), actively connected with an axially movable displacement disk (6). The pressure chamber (26) may be connected by means of a valve (32) with the atmosphere.
