Abstract
A swash plate compressor with single ended pistons improves piston stability by providing the ends of the pistons with open, conical rims, the outer surfaces of the which match, and thereby enlarge, the outer surface area of the pistons. The pistons therefore have increased sliding support within the cylinder bores, but without significant added mass. The pistons work in cooperation with matching conical protrusions on the discharge valve plate, which substantially fill the interior of the rims at piston full stroke. The piston compression ratio is therefore kept substantially the same.
