Sentence Examples


  • The compressor may be driven by a steam engine or in any other convenient manner.
  • The compressed air, leaving the compressor at the temperature T2, passes through the cooler, where it is cooled by means of water, and is then admitted to the expansion cylinder, where it is expanded to atmospheric pressure, performing work on the piston.
  • Another, perhaps the principal, feature was the interchanger, an apparatus whereby the compressed air was further cooled before expansion by means of the comparatively cold air from the room in its passage to the compressor, the same air being used over and over again.
  • Further, though the interchanger is still used by some makers, it has been found by experience that, with properly constructed valves and passages in the expansion cylinder, there is no trouble from the formation of snow, when, as is the general practice, the same air is used over and over again, the compressor taking its supply from the insulated room.
  • With dry compression, vapour alone is drawn into the compressor, and the temperature rises to as much as 180 or 200 degrees.
