    Abstract: A volume control device for a sealed reservoir for storing oil under pressure and which supplies oil to a power circuit. The volume control device has an expansible bellows assembly which contracts upon a predetermined increase of volume of oil in the reservoir to bring a rod into engagement with a ball check valve and unseat the valve for dumping of oil overboard from the reservoir. The dumping of excess oil from the reservoir is controlled by an increase of volume of oil in the reservoir, rather than an increase in oil pressure.

    Abstract: In the gas shortage detection device of a piston-type hydropneumatic accumulator, a control rod slidably mounted in the cylinder head on the gas side is displaced under the action of the thrust exerted by the piston when this latter comes closer to the cylinder head than a predetermined distance. A flexible motion-reversal coupling element such as an inextensible cord which works in traction and has a predetermined dead range of travel is placed between the piston and the sliding rod.Correct performance of the detection device can thus be checked by partial draining of the oil compartment, the detection device being triggered into operation when the piston comes close to the bottom end of the cylinder.

    Abstract: A hydraulic system pressure fluid accumulator apparatus is disclosed that meets peak load demands beyond the flow capacity of the system pump. Gas cylinder actuation of the accumulator piston augmented by system pressure feedback actuation of the piston metered by a pressure regulator valve maintains accumulator output pressure level substantially independent of piston displacement.

    Abstract: A hydro-pneumatic accumulator of the type in which a piston slidable within a cylinder separates a liquid and a gas under pressure, is provided with an end closure of a non-magnetic material within which closure is provided a magnetically actuated switch. Movement of the piston causes a permanent magnet to be moved relative to the switch whereby movement of the magnet into the actuating range of the switch causes the switch to be actuated and an indication of the level of the liquid in the accumulator to be provided.

    Abstract: A fluid expulsion system including a tank having a fluid therein and a piston for expelling the fluid from the tank. The piston is mounted in the tank with a gas generator on the first side of the piston and the fluid on the second side of the piston. Responsive to actuation of the gas generator pressure is built up on the first side of the piston and the piston is displaced against the fluid to force the fluid from the tank. The piston and tank passage of the fluid past the piston because of leakage and extrusion due to the gap created between the piston and tank wall responsive to tank expansion under pressure.

    Abstract: An accumulator arrangement for providing constant pressure high flow rates in hydraulic systems. The accumulator piston has a piston area directly connected to a container of pressurized gas and an annular piston area of larger diameter which is connected to the container through a pressure regulator. The regulator senses the container pressure and the pressure acting on the annular piston area and increases the pressure on the annular piston area as the container pressure decreases during expansion. Between high flow periods, when the accumulator is refilled by hydraulic fluid under pressure, the gas acting on the small diameter piston is recompressed and forced back into the container and the gas acting on the annular piston area is vented to the atmosphere through the regulator.
