Abstract
A piston and rod subassembly is reciprocally mounted in a piston tube subassembly. A transfer tube is concentrically mounted in the rod and is in fluid communication with a pressurized source of fluid. A solenoid valve subassembly provides real time damping of relatively high frequency inputs by opening and closing a bypass channel formed in the actuator. Relatively low frequency inputs are actively controlled as fluid passes to and from the pressurized source of fluid. An outer body tube includes a fluid trapping chamber to prevent leakage from the actuator.
