Beschreibung
Zusammenfassung:	The compressor, with rotating assemblies of low inertia, and of compact construction, comprises, housed in a housing, two hollow rotors (5, 6), for example out of plastic material, fixed respectively on a front shaft member (20, 21) journalled in a front bulkhead (26) and each supported at the rear by a rear bearing assembly (11) fixed to a rear end wall (2) of the housing and entirely contained within the internal space (7, 7) in the rotor. The drive is provided by the female rotor (6). The inner surfaces of the housing and the outer surfaces of the rotor threads are coated with an overthickened layer of an erodable coating material containing particles of a dry lubricant material.
