Abstract

A small multistage nonlubricated compressor for air and other gases has an open crankcase cooled by a fan, the stages being arranged in cruciform for cooling. In each stage, the piston is guided by a cylindrical crosshead. The crossheads are guided in cylindrical sleeves of self-lubricating plastic such as polytetrafluoroethylene. The pistons are guided in cylindrical sleeves of graphite and have piston rings of self-lubricating plastic.
