Abstract
A piston seal of a liquid-operated cylinder includes a main seal ring that slidably contacts the inner circumferential surface of the cylinder tube; an O-ring that imparts a force causing an outer circumference of the main seal ring to move closer to the inner circumferential surface of the cylinder tube by pressing onto an inner circumference of the main seal ring; and a sub-seal ring that is disposed parallel to the main seal ring at a position further toward the cushion pressure chamber and is pressed by the main seal ring, as pressure from the drive pressure chamber is applied to the main seal ring, to slidably contact the inner circumferential surface of the cylinder tube.
