    摘要: Disclosed is an actuator that includes a cylinder having an input port, a piston disposed at least partially inside of the cylinder, and one or more piston rings disposed in a circumferential piston ring groove or grooves. The actuator also includes at least one spring, inserted into the circumferential piston ring groove adjacent to the one or more piston rings and a high pressure side of said piston ring. The spring preloads the one or more piston rings to seal between a low pressure face of the one or more piston rings and a low pressure face of the circumferential piston ring groove. The invention also includes a method for moving an adjustable seal in a radial direction using the piston-ring sealed actuator. The method includes moving the adjustable seal in an axial direction, breaking a primary axial contact between the adjustable seal and a primary sealing face.
