Abstract
Methods, apparatuses, and systems for circumferential sealing of piston assembly in a piston actuator. A piston assembly for a piston actuator includes a piston including an extending surface, a retracting surface, and a circumferential surface that connects the extending surface and the retracting surface. The piston is adapted to engage and seal against an interior surface of a cylinder bore of an actuator. The piston assembly includes a first unidirectional passage connecting the extending surface and the circumferential surface. The first unidirectional passage allows hydraulic fluid to flow unidirectionally from the extending surface to the circumferential surface through the piston to energize a circumferential seal disposed on a seal groove in the circumferential surface during an extension stroke of the piston
