<p>This invention relates to the art of pressure vessels of the type comprising a rigid container having an opening at one end and an oil port at its other end. The container has a deformable partition therein intervening between the opening and the oil port and defining a gas chamber and an oil chamber. A rigid member is secured in the opening of the container and has a bore therethrough. A layer of resilient material, which defines a disc portion extends over the inner end of the bore. The periphery of such disc portion is bonded to the surface of the rigid member through which the inner end of the bore extends, said disc portion having passage means therethrough positioned between the bonded periphery thereof and the axis thereof, the inner end of such passage means normally abutting against such surface, the portion of said disc inwardly of its bonded periphery being movable away from such surface.</p> |
