Abstract (en)

[origin: WO2007054414A1] Prior art discloses gas bearings, which use a stream of gas to support a piston. This is achieved by micro-nozzles in the cylinder wall of a cylindrical element. Micro-nozzles of this type are susceptible to dirt retention. According to the invention, channels (11, 12) that run parallel with the cylinder axis are provided on the inner face of the base element, some of the channels (11) supplying gas via the compression chamber and the other channels (12) being connected to the gas reservoir.
