Abstract

The compressor has two rotors each with two blades or teeth, a housing (2) round the rotors, forming feed chambers with the blades, a bearing device for the rotors separated from the chambers by a sealing device, a transmission device to hold the rotors in operation, and an oil cavity containing at least part of the transmission device.
