Abstract: A hydraulic accumulator including a fluid chamber and a displaceable piston that is connected to a piston position-measuring means is disclosed. Embodiments of the hydraulic accumulator can provide a device that measures the available fluid volume in the accumulator. In embodiments, the displaceable part of the piston may separate fluid volume from gas volume, and may be connected to a wire that runs through the fluid volume and exits the outside of the accumulator through a sealed opening. Further, in embodiments, the wire may be led over pulleys and through a hollow member connected to the accumulator. The position of an associated metallic core member can be electrically monitored to provide position and fluid volume information.

Abstract: A system for remotely controlling an undersea device. The system employs a gas-pressurized liquid reservoir that can be recharged from at least one replaceable gas bottle. A pressure-regulating valve is employed to control the pressure of the liquid leaving the reservoir. A number of one-shot units, each in the form of a squib-actuated valve coupled with a piston accumulator, are employed to create a hydraulic pilot for a hydraulic direction control valve. The control valve functions to direct pressurized liquid from the reservoir to a hydraulic actuator or other type of hydraulic device.

Abstract: An accumulator has a piston axially slidably disposed in a cylinder mounted in a casing, the cylinder and the piston jointly defining a reservoir communicating with an inlet/outlet port in the casing. A piston rod axially movably disposed in the casing has an end slidably fitted in the cylindrical hole of the piston. The piston rod is normally urged by a spring to force the piston into the reservoir. The accumulator also includes a switch mechanism for detecting the position of the piston in the cylinder. The switch mechanism may comprise a reed switch, a light-sensitive switch, a pressure-sensitive switch, or a pushbutton switch.

Abstract: A gas charged accumulator includes a gas chamber and a hydraulic reservoir on opposite sides of a movable member. A fill passage for pressurizing the gas chamber includes a movable operating device for operating an indicator when the accumulator is substantially discharged. Gas flows directly past the indicator operating device when the gas chamber is pressurized through the fill passage. A normally closed switch assembly is mounted in the fill opening outwardly of the indicator operating device subsequent to pressurization of the gas chamber. The indicator operating device holds the switch assembly in an open position when the accumulator is charged and provides closing of the switch when the accumulator is substantially discharged.
