The compressor has two rotors ( 14, 16 ), which are rotatably mounted in a housing ( 10 ) by means of a shaft each, the rotors ( 14, 16 ) rotating without contact with the housing. The rotors ( 14, 16 ) consist of a powder-metallurgical Al-Si alloy, and the housing ( 10 ) consists essentially of aluminum. |
