摘要： A combination oil/gas spring includes a first hollow casing, a piston capable of fluid-tightly sliding within the casing, a rod connected rigidly with an end portion thereof to a central portion of the piston, a first chamber containing an actuating rod provided inside the casing, a second sealed chamber provided within the same casing on the opposite side of the piston, a mass of hydraulic fluid filling the second sealed chamber, a second hollow casing and a respective second piston provided to slide therewithin, a first conduit connecting the interior of the second sealed chamber with the interior of the second hollow casing, a first valve connected to the first conduit and adapted to selectively open and close it, a second conduit being provided to connect an expansion vessel to the first conduit at a position upstream of the first valve, and a second valve being provided on the second conduit. The combination oil/gas spring also includes a pressure-exerting unit adapted to act by exerting a controllable pressure upon the surface of the liquid in the expansion vessel.
