Abstract
Abstract A compressor having a gas-compressing cylinder-and-piston arrangement with inlet and discharge plenum chambers in flow communication with inlet and discharge ports and with the cylinder. The chambers are side-by-side, sharing a common wall which wall radiates heat from the discharge plenum chamber into the inlet plenum chamber. Troughs are arranged in the chambers more positively to direct gas flow, especially away from the commonly shared wall and all other heat-radiating walls, to inhibit gas turbulence and to reduce preheating, thereby to enhance compressor efficiency.
