ABSTRACT:
The cylinders of the compressor each have a guide piston connected with a work piston with each being reciprocally mounted within a guide cylinder and work cylinder. In addition, seals are provided between the guide piston and the guide cylinder within a half-portion of the guide piston proximate to the work piston while a scraper ring is provided in a second half-portion of the guide piston remote from the work piston in order to meter lubricant between the guide piston and guide cylinder. Excess lubricant which is splashed from the crank case into the guide cylinder is returned via the scraper ring to the crank case.
