Abstract
Devices for compressing a gaseous fluid each have a housing with a cylindrical cavity configured in the housing, in which a spiral nozzle assembly is arranged. As such, the spiral nozzle assembly is configured with a spirally revolving winding with a winding surface, which at least partially sealingly abuts an inner wall of the cylindrical cavity. Recesses configuring a filter function and a bypass function are arranged on the winding surface of the spirally revolving winding, or the winding surface of the spirally revolving winding is arranged to be spaced apart from the inner wall of the cylindrical cavity with a distance configuring a gap for a filter function and a bypass function in at least one partial area. Additionally thereto, or instead thereof, recesses configuring a filter function are each arranged on a collar surface of a collar connected to the spiral nozzle assembly.
