Abstract
The Compressor comprises three stages of compression, having three cylinders, each of the latter having a piston reciprocable therein. Two of the pistons are in-line along a common axis, and the cylinders therefor are in confronting relationship. The third cylinder lies along an axis which traverses the two-piston axis. All three pistons are reciprocated by two connecting rods, in that the in-line pistons are joined by tie rods. Both connecting rods are coupled to the single crank of a crankshaft which is journalled in a crankcase, and all three cylinders are removably bolted to the crankcase.
