A multistage drum compressor has its stage cylinders arranged in ascending order around the axis of a shaft which operates the various stage pistons and which rotates in a direction opposed to the order of the stages, whereby the stage pistons are actuated in reverse stage order. The compressor incorporates internal ducts for providing interstage cooling of the gas being compressed by means of a circulating liquid coolant system.
