ABSTRACT:
An oilless gas compressor includes a motor containment vessel containing a motor for driving the compressor and a crankcase attached to the motor containment vessel. The crankcase and the motor containment vessel are fluidly connected and together define a sealed, pressurizable interior cavity in which the rotatable motor shaft is disposed. The compressor further includes a cylinder mounted upon the crankcase, the cylinder having a piston disposed therein. The piston is connected to the shaft for reciprocation of the piston within the cylinder. The cylinder also includes a gas intake valve, fluidly connected to the compressor suction inlet port, and a gas discharge valve, fluidly connected to the compressor discharge outlet port. The oilless gas compressor, in which the need for perimeter rotating shaft seals is obviated, is suitable for compression of precious or toxic gases or flammable gases, such as natural gas.
