Abstract
A piston for a fluid pressure chamber having an arcuate longitudinal axis. Such piston comprises an assemblage of two spherical bodies in side-by-side relationship and interconnected by a universal pivot. Each spherical body carries a circumferential piston ring receiving groove and piston rings are mounted in such grooves to provide a sliding and sealable engagement with the walls of the fluid pressure chamber as the piston moves along the curved longitudinal axis of such chamber.
