ABSTRACT:
A multi-cylinder compressor of the type suitable for use in a vehicle air-conditioning system includes a pair of axially spaced cylinder blocks for receiving a refrigerant fluid therein for compression. First and second sets of pistons are respectively reciprocated within the front and the rear cylinders, respectively by means of first and second sets of rods of different axial lengths. Also disclosed is an improved lubricating system for a compressor which includes a flapper element located near the oil hole to direct oil to the shaft seal for both clockwise and counterclockwise rotation of the compressor. The compressor may also include a slanted surface on the cam rotor for splashing oil onto the compressor housing wall.
