  • Patent number: 6378848
    Abstract: A gas spring apparatus comprises an outer tube, a cylinder held in the outer tube, and a rod having a piston located in the cylinder. The rod is inserted into the cylinder through a sealing portion. The interior of the cylinder is divided in two, a first liquid chamber situated on the side of the sealing portion and a low-pressure gas chamber situated on the side remoter from the sealing portion, by the piston. A space between the inner surface of the outer tube and the outer surface of the cylinder is divided between a high-pressure gas chamber and a second liquid chamber by a metal bellows. A first liquid chamber and a second liquid chamber communicate with each other by liquid communicating portions. A gas is charged in the high-pressure gas chamber at a higher pressure than in the low-pressure gas chamber.
