摘要： This invention relates to a pressure vessel of the type having a rigid container to be filled with fluid, usually oil and gas under pressure and having a deformable partition intervening between such fluids and more particularly relates to a pressure accumulator of relatively large size in the order of say 40gallon capacity and which is extremely heavy and in the order of say 300 to 400 pounds. The partition is a bladder closed at one end and having an open mouth at its other end. The container has longitudinally aligned ports at opposed ends and is designed to be mounted in vertical position with the upper port receiving a gas fitting to which the mouth of the bladder is secured, for charging of the bladder with gas under pressure and the lower port having an oil fitting for charging the container with a fluid such as oil under pressure. The oil fitting has a mounting flange associated therewith to permit rigid mounting of the container in upright position on a suitable complementary flange that is connected to a source of oil under pressure such as an oil line. The gas fitting is mounted in the upper port so that it may readily be removed together with the bladder without need to disconnect the accumulator from the oil line and without need to handle the heavy accumulator.
