Title: Gas compressor with synchronous rotors - which have four interconnecting pockets accommodating sliding vanes
Inventor: HAENDLER ALEXANDER
IPC: F04C18/54
Filed: 1975-07-03
Abstract: Compressor for gaseous media compresses large quantities of gas already at low rotating speeds. The medium is compressed in stages in chambers whose volume is progressively reduced. The compressor has three rotating bodies (5, 5a, 4, 4a) which rotate in the same direction and which approach synchronously within a half rotation. The enclosing truncated conical hollow bodies (5, 5a) move on each other due to eccentric arrangements. The compression chambers have variable volume due to the relative movements and by means of a vane wheel (4, 4a, 4b) which moves in and out of the pockets of the rotating bodies. These volumes are maximum before and minimum, approaching zero, after the compression of the medium. This ensures vibration free running and very low noise level. Only shaft bearings are lubricated and other components have very low wear due to absence of direct contact.
