ABSTRACT:
An easy-to-assemble compressor having a pair of parallel, double-headed pistons reciprocably mounted in respective cylinder chambers in a compressor housing. The pistons are mounted on a crankshaft via Scotch-yoke-type sliders slidably engaged in the respective pistons for reciprocating movement in a direction normal to the piston axis. The sliders convert the rotation of the crankshaft into linear reciprocation of the pistons. The dimensions of these sliders are determined in relation to the other parts of the compressor so that, during the assemblage of the compressor, the sliders may be mounted in position by being passed over the opposite end portions of the crankshaft following the mounting of the pistons and crankshaft within the housing.
