Abstract: A piston-in-sleeve accumulator includes a cleaning element positioned on the piston and configured to remove and prevent debris from lodging between the piston and a cylindrical nonpermeable sleeve within which the piston slides. A seal on the piston is positioned to engage an opposing surface in the event of a leak, and thereby prevent the possibility of a complete drainage of pressurized fluid from occurring through the accumulator's fluid port. A position contactor switch is further provided to signal position of the piston within the accumulator.

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: A system for determining the location of a piston within an accumulator is provided in which a short circuit is created between elements in the accumulator and the piston which is movable within the accumulator. As the piston moves along the longitudinal axis of the accumulator, the circuit's electrical characteristics (e.g., voltage, resistance, current) vary in accordance with the length of the circuit. Measurement of these electrical characteristics allows for precise determination of the piston location relative to the accumulator. In a commercial embodiment, the invention can be utilized to determine fluid volumes in an accumulator by monitoring the location of the piston. This invention overcomes prior art systems because, inter alia, it does not require electrical sensory equipment, enables remote monitoring, maintains system integrity and functions irrespective of container wall thickness.
