Rotary positive displacement machine e.g. multi-level turbo compressor, for compressing gas, has drive disks, where number of disks provides parallel and out of phase promoting stages that are conveyed from intake line into pressure line

摘要

The machine has a transmission element that is formed by a sliding body (3) or by pairs of magnets, where the sliding body runs into a groove. A housing has control grooves for specifying opening times of an inlet and an outlet of the machine. A common drive disk (2) drives a displacer pair (V). Drive cams are displaceably arranged at an angle. The number of drive disks provides multiple parallel and out of phase promoting stages, where all the stages are conveyed from a common intake line (S) into a common pressure line (D).
