SELF-REFILLING HYDRAULIC ACTUATOR ABSTRACT A piston slides in a fluid-filled piston chamber for damping or snubbing the movement of an object connected thereto. Attached to the piston is a piston rod which is disposed in the main fluid supply reservoir located below the piston chamber, at the lowest point in the apparatus. As the piston moves, the associated movement of this rod in the reservoir varies its displacement therein, thereby displacing fluid into a vented secondary reservoir which is located above the piston chamber, at the highest point in the damper apparatus. Any leakage from the piston chamber collects in the reservoirs. Both reservoirs are in fluid supply connection with the piston chamber so that piston movement causes fluid to flow into the chamber from the reservoirs so as to keep the chamber completely filled with fluid at all times. Both reservoirs supply fluid to the piston rod seals, which are thereby always immersed in fluid.
