Abstract

The present invention relates to a rotary piston machine comprising a housing which consists of a flange housing, an intermediate housing and an end housing. The flange housing has a flange extending there from landing the machine on a suitable support. A shaft is rotatively supported within the housing, and a rotor is fixedly mounted on the shaft and adapted to rotate together with the shaft. A hollow gear for farming compressing chambers is also located within the housing for cooperation with the rotor. A commutator is fixedly mounted within the flange housing means and is adapted to supply pressure medium to and to remove pressure medium from the compressing chambers.
