Abstract (en)
[origin: WO2006077175A1] The invention relates to a vacuum side channel compressor (10) comprises a pump stator (14) and a pump rotor (12), which surround a side channel (31, 32, 33, 34). An axial bearing (22) is provided for mounting the pump rotor (12). A sealing gap (40) is formed next to the side channel between the pump stator (14) and the pump rotor (12), part of which forms a conical ring, whose imaginary conical apex (50) lies in the vicinity of the axial bearing (22).
