Supercharger device i.e. exhaust gas turbocharger, for improving performance of drive device of drive assembly for e.g. Otto engine of vehicle, has connecting line for performing flow connection between compressor inlet and body housing

摘要

The device (1) has a compressor (2) driven by an exhaust turbine (6) and/or a driving apparatus (12). A shaft (3) is retained in a body housing (9) and connected with the compressor. The compressor compresses gas i.e. air, which is supplied through a compressor inlet (4). A flow connection is provided between the inlet and the housing by a connecting line (19) e.g. hose and pipe. The housing retains shaft bearings (10, 11) of the shaft and the driving apparatus. A suction line (14) is provided between the compressor inlet and a gas inlet (13) comprising a filter e.g. fine or micro filters. The driving apparatus is designed as a permanent excited electromotor. An independent claim is also included for a drive assembly comprising a fuel cell supplied with compressed gas.
