Abstract
A lost motion piston assembly comprising a lost motion cavity formed within a piston and a lost motion piston disposed within the lost motion cavity. The lost motion piston forms a sealed gas cavity. The sealed gas cavity contracts when the actuator is extended under pressure into the cylinder space and expands under pressure when the actuator is retracted by relieving pressure in the cylinder space.
