COMBUSTION WHEEL

摘要

The invention relates to a device for the compression of combustion air, especially for the internal combustion engine of a motor vehicle. Said device comprises a housing (12), at least one air inlet (28) which guides air into the housing (12) and at least one air outlet (40) which guides air out of the housing (12) and at least one compression wheel which is actuated by a shaft (44) and which is arranged in a compression chamber (32) inside the housing (12), also comprising a plurality of compressor blades (54, 80, 106, 120) which are arranged on the periphery of the compressor wheel (42) which is arranged between the at least one air outlet (28) and the at least one air inlet (40) of the housing (12) such that the air supplied to the combustion process can be compressed by rotating the compression wheel (42). According to the invention, the at least one combustion wheel (42) is made essentially of plastic.
