Electrically powered charge air compressor has compressor wheel movable between working and idle positions, and is at least partly removed from compression section in idle position

摘要

The device has an electric motor with a stator (4) and rotor (5) for driving a compressor wheel (3) in a compressor housing (2) with at least one air inlet (21) and outlet (22) connected by a flow channel (8,9) in the housing. The compressor wheel can be moved between working and idle positions, so that the wheel is at least partly removed from a compression section (8) of the flow channel in the idle position.
