Definitions
- the piston of a compressor should be stored by a gas bearing.
- part of the gas compressed by the compressor is branched off from the useful gas stream and passed through nozzles into the gas bearing.
- the problem with this arrangement is the loss of useful gas in particular because the gas loss depends on the thermodynamic operating point of the compressor. That at high end pressure of the gas more gas is lost than at low final pressure. As a result, the gas loss and the
