Abstract
A displacement machine of spiral-type construction for a compressible medium includes a displacement body having a carrier disc and helical blades extending out from both sides of the carrier disc. The carrier disc has a hub which is supported by a hub bearing on an eccentric disc which is part of a driven drive shaft. The drive shaft is supported inside a housing by a first bearing and a second bearing. These bearings are arranged in receptacles which fully project into the feed chambers of the housing so that the bearings are positioned in close proximity to the eccentric disc.
