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.

The invention relates to a bypass valve, particularly a two-way valve for exhaust gas flows from motor vehicles, having a valve housing and an actuating mechanism with a valve flap and two ports for fluid outlet, which are embodied as alternately sealable by the valve flap, and one port for fluid intake, characterized in that at each of the ports for fluid outlet an adapter and sealing ring is provided, arranged at least partially and fluid-tight in the valve housing, wherein the valve flap can be positioned fluid-tight on the adapter and sealing ring.

Sheet metal exhaust bypass valve

A heat exchanger for an exhaust gas train of a motor vehicle with an exhaust gas carrying exchanger tube that is formed separately and is disposed in a closed housing formed separately, a coolant flowing through the housing and around the outer surface of the exchanger tube. The housing includes a housing portion that forms one common mechanical interface for connecting the heat exchanger to the exhaust gas train and a coolant circuit of the motor vehicle.
