Abstract
A horizontally opposed compressor having a crankshaft and an even number of diametrically opposed cylinders, each opposed cylinder having a piston and a single connecting rod cooperatively associated therewith, one of the connecting rods having a crankshaft bearing portion on one end and a wrist pin bearing portion on the other end, the other connecting rod having two spaced apart legs, each leg having a crankshaft bearing portion on one end, the other end of the legs coming together to form a wrist pin bearing portion and a wishbone shaped connecting rod, the spacing between the legs being sufficient to allow the crankshaft portion of the one connecting rod and the associated portion of the crankshaft to rotate between the legs so that the reciprocating mass forces associated with the opposed cylinders are generally equal and opposite and cancel each other to produce a smooth running compressor.
