Abstract
An automotive air conditioning compressor of more compact and efficient design is achieved with a unique cylinder bore and piston shape. While the cylinder bores and pistons are arrayed in a circle about the central axis of the round cylinder block, the bores and pistons themselves are not round in cross section. Instead, each has a pair of flattened sides lying more or less parallel to radial planes of the cylinder block. As a consequence, only solid webs separate the cylinder bores, not empty spaces, as in a conventional block. The ratio of total bore volume to block volume is greater, and the compressor is more compact for a given capacity. In addition, the non round cross section of bores and pistons resists piston twisting.
