  • the heat exchanger is set up for heat exchange between the working medium after compression in the second cylinder and the drive medium before it enters the first cylinder of the pressure booster.
  • the temperature of the drive medium in the compressed state can advantageously be increased before the drive piston is acted upon by the drive medium in the compressed state.
  • a higher work output is available for operating the high-pressure piston, so that the efficiency of the compressor can be increased.
  • This principle can be used with different types of compressors, in particular with a single or double-acting, single-stage or two-stage compressor.
  • the compressor can also be designed as a piston compressor, single or double-acting, single-stage or two-stage.
  • the location and direction information relate to the direction of flow of the drive medium or the working medium in compressor operation.

  • the heat exchanger is designed as a regenerator, with heat storage being provided in a heat exchanger mass.
  • a plate heat exchanger or a tube-in-tube heat exchanger can be provided as the heat exchanger.
  • a wide variety of designs of heat exchangers are known with which the heat content of the compressed working medium can be transferred to the compressed drive medium.
  • the compressor is designed to be fully hermetic or semi-hermetic.
