Abstract:
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.
