Abstract
A swash plate driven piston compressor includes means to maintain the pistons on their respective cylinder bore axes. A resilient alignment ring bears on the radial inner sides of the pistons at a point near the back ends of the pistons. The ring moves passively with the swash plate, without affecting its operation. The ring prevents the pistons from tipping radially inwardly and off their axes as they retract. The piston design is not appreciably changed, and the ring fits within otherwise empty space within the compressor housing.
