摘要： PURPOSE: A liquid container is provided to prevent the creation of negative pressure in a liquid container for a pressure medium of a hydraulic device due to pressure fluctuation in the liquid container by providing the pressure container with a means for compensating pressure between the atmospheric pressure and pressure in the liquid container, and a means for compensating the volume difference of the pressure medium, separately from each other. CONSTITUTION: The liquid container(1) for supplying an internal pressure medium(2) to a hydraulic device through a conduit(8) and receiving an excess pressure medium and bubbles has a casing (1a) closed with a cover(5). A bellows(3) for compensating the difference of two pressure levels of the pressure medium is provided in the container(1), and a gas permeable diaphragm(4) is fitted to the end face(11) of the bellows(3). An inner chamber(9) functioning as an air cushion(10) is partitioned by the bellows(3) and diaphragm(4). The diaphragm(4) is pressed by the air cushion(10) until coming in contact with the pressure medium(2), and when the pressure of the pressure medium(2) rises, pressure fluctuation is absorbed by the deformation of the bellows(3).

摘要： The invention provides a metal bellows type accumulator having an outer shell provided in its one end with a pressure introducing passage in an opening manner, an axially expandable metal bellows including peak portions directed to an outer side in a radial direction and trough portions directed to an inner side alternately in an axial direction, having an axially fixed end to the outer shell and separating an inner chamber of the outer shell into a pressure introducing chamber and a gas chamber charged with cushion gas, and a support member arranged in an inner periphery of the metal bellows, fixed to the outer shell and constructed by a cushioning member. A clearance in a radial direction between the trough portions of the metal bellows and the support member is smaller than a clearance in a radial direction between the peak portions of the metal bellows and the outer shell.

摘要： 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.

摘要： A device (1) adjusts a media pressure relative to an ambient pressure defined by a depth-dependent sea water pressure during use of the device (1). The sea water pressure acts on a compensator device (35) that permits a reversible change in length or elongation. At least two compensator elements (41) of the compensator device (35) are provided in series in the direction of the change in length or elongation.

摘要： The invention provides an accumulator which can reduce the number of the parts of the pressure fluctuation absorption mechanism at the liquid expanding time, can simplify assembling and can reduce a cost of the parts. The accumulator has a seal holder which is provided in a bellows cap, and a plate-like seal which is retained by the seal holder. The seal holder is provided with an inward flange-like outer peripheral side engagement portion, and the seal is provided with an outward projection-like inner peripheral side engagement portion which is arranged in an outer peripheral surface of a seal main body and is made of a rubber-like elastic body engaging with the outer peripheral side engagement portion. The bellows cap moves to a position where liquid pressure and gas pressure are balanced with the seal seating on a seat surface due to difference in pressure receiving area.

摘要： An accumulator has a seal member retained to a port hole side of a bellows cap via a seal holder. The seal member comes into contact with a seal portion so as to occlude a liquid chamber in the case that an operation of a device stops and the pressure within a pressure piping is lowered. The seal member moves in a direction that the bellows cap moves away from the seal portion while being in contact with the seal portion when the liquid confined in the liquid chamber thermally expands in a state in which the liquid chamber is occluded. The seal member is obtained by attaching a flexible portion constructed by a rubber-like elastic body to an outer peripheral surface of a rigid plate, and the flexible portion allows relative movement of the bellows cap by shear deformation on the basis of engagement with the seal holder.
