Abstract:
The invention relates to a pressure means storage device, comprising a housing (1), the inside of which is divided into two chambers (3, 4) by a media separation element (2). The first chamber (3) is filled with a gas and the second chamber (4) is filled with a liquid. A bottom valve (6) which allows the second chamber (4) to be filled with the liquid and prevents said second chamber (4) from being completely emptied is provided in a hydraulic connection (5), the closing body (7, 40) of said valve being activated by the media separation element (2). According to the invention, the closing body (7, 40) can be moved by means of the media separation element (2 or 16) into a position in which it performs the function of a hydraulic piston. This prevents the bottom valve from being damaged and any unwanted leakage of the liquid, hereby considerably increasing the functional reliability.

Abstract:
A linear position sensing system includes a sensor, a conduit and an enclosure. The sensor has a connector and a converting element, where the connector includes a first end attached to the converting element and a second end that passes through the conduit and is configured for attachment to a moveable element of an external device. The enclosure houses the sensor. The conduit includes a first end fitting that is attached to the enclosure and a second end fitting that is affixed at a port or other aperture of the external device. The second end of the connector is configured to be inserted in the port other aperture and attached to the moveable element without disassembly of the external 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.

Abstract:
A method for using a band sensor for defining a position of a component in an interior of the housing. At least one magnet is coupled with a winding drum of the band sensor so the magnet is drivable in rotation about a magnetic rotation axis wherein a pole axis is disposed transverse to the magnetic rotation axis. The measuring band length varies with percentage of wind-up which is numerically compensated by processing electronics.
