The invention relates to a side channel compressor, comprising a housing shell and a running wheel. The running wheel is mounted to be rotatable with respect to the housing shell to provide two annular sealing areas between the housing shell and the running wheel. The housing shell between the first and the second sealing area can be made of one piece. The gap dimensions of the first and second sealing areas can be adjusted by means of a disc spring/nut system or a wobble means. A fan impeller may be fixed on the motor shaft, and the housing shell can comprise cooling ribs, wherein the cooling ribs are arranged and formed such that the air conveyed by the fan impeller sweeps through the cooling ribs. One of the annular sealing areas can include a dead volume chamber. The housing shell may be a casting or a machined extruded profile.

The invention claimed is: 1. A side channel compressor, comprising: a housing shell; a running wheel which is mounted to be rotatable with respect to the housing shell to provide two annular sealing areas between the housing shell and the running wheel; the housing shell between the first and the second sealing area being made of one piece and the housing shell being sealed against an ambiance by a lid having a small construction height, the running wheel being substantially located in the housing shell, wherein the gap dimensions of the first and second sealing areas are adjusted by means of a disc spring nut system. 2. The side channel compressor according to claim 1, wherein the running wheel is fixed on a running wheel receptacle by means of a disc spring and a nut, wherein the running wheel receptacle comprises a thread for screwing on the nut, wherein the disc spring is clamped between a flange of the running wheel receptacle and the running wheel so that the disc spring presses the running wheel against the nut, wherein the running wheel is axially displaceable with respect to the running wheel receptacle by tightening or loosening the nut. 3. The side channel compressor according to claim 2, wherein the running wheel comprises a shoulder which produces a form closure with the nut and that a locknut is tightened with respect to the nut so as to ensure a torque transmission from the running wheel receptacle to the nut. 4. The side channel compressor according to claim 1, wherein the disc spring/nut system is fixed on the shaft of a motor, wherein the housing of the motor is fixed to the housing shell. 5. A side channel compressor, comprising: a housing shell; a running wheel which is mounted to be rotatable with respect to the housing shell to provide two annular sealing areas between the housing shell and the running wheel; the housing shell between the first and the second sealing area being made of one piece and the housing shell being sealed against an ambiance by a lid having a small construction height, the running wheel being substantially located in the housing shell, wherein the running wheel is fixed to the shaft of a motor, wherein the housing of the motor is fixed to the housing shell by means of screws and springs such that by turning the screws the springs are more or less compressed and the position and orientation of the motor and the running wheel with respect to the housing shell is defined by the driving depth of the screws. 6. A side channel compressor, comprising: a housing shell; a running wheel which is mounted to be rotatable with respect to the housing shell to provide two annular sealing areas between the housing shell and the running wheel, the running wheel is fixed to the shaft of a motor, wherein the housing of the motor is fixed to the housing shell by means of screws and springs such that by turning the screws the springs are more or less compressed and the position and orientation of the motor and the running wheel with respect to the housing shell is defined by the driving depth of the screws. 7. The side channel compressor according to claim 6, wherein the housing of the motor is firmly connected to a wobble plate which is, in turn, connected to the housing shell by means of the screws and the springs. 8. The side channel compressor according to one of claim 6, wherein a fan impeller is fixed to the end of the motor shaft facing away from the running wheel and the housing shell comprises cooling ribs, wherein the cooling ribs are arranged and formed such that the air conveyed by the fan impeller sweeps through the cooling ribs. 9. The side channel compressor according to claim 8, wherein the housing shell has a honeycomb structure on its outside. 10. The side channel compressor according to claim 6, wherein the housing shell has a honeycomb structure on its outside. 11. The side channel compressor according to claim 6, wherein the housing shell has a honeycomb structure on its outside, wherein a running wheel is mounted to be rotatable with respect to the housing shell to provide two annular sealing areas between the housing shell and the running wheel. 12. The side channel compressor according to claim 6, wherein at least one of the annular sealing areas includes a dead volume chamber. 13. A running wheel for a side channel compressor comprising: two types of blades, namely functional blades and intermediate blades, wherein the functional blades are slightly higher than the intermediate blades, wherein the height of the functional blades is dimensioned such that the functional blades reach as far as the interrupter of the side channel compressor, with the exception of a sealing gap, if the running wheel is installed in a side channel compressor, wherein the height of the intermediate blades is dimensioned such that a considerable gap is maintained between the intermediate blades and the interrupter of the side channel compressor if the running wheel is installed in a side channel compressor. 14. The running wheel for a side channel compressor according to claim 13, further comprising a housing with a shell cast or machined extruded profile. 15. The running wheel for a side channel compressor according to claim 13, further comprising a housing shell with an edge surrounding a round cavity with such a depth that the round cavity can receive the running wheel provided for the side channel compressor. 16. The running wheel for a side channel compressor according to claim 13, further comprising a housing shell, wherein a running wheel is rotatably mounted with respect to the housing shell to provide two annular sealing areas between the housing shell and the running wheel.
