Abstract: A system includes a pump, accumulator, a sensor which measures line pressure in a fluid circuit, and a controller. The controller plots and calculates respective slopes of first and second sets of measured pressure values from the sensor, calculates a slope ratio, and compares the slope ratio to a threshold. The controller also records the pre-charge pressure as the point of intersection of lines representing the slopes when the ratio exceeds the threshold. A control action is executed when the pre-charge pressure drops below a calibrated minimum threshold. A method includes measuring the pressure values, calculating the respective slopes and the slope ratio, comparing the slope ratio to a ratio threshold, recording the point of intersection of lines representing the slopes as an interpolated pre-charge pressure value when the ratio exceeds the threshold, and executing the control action.

Abstract: A hydraulic control system in a working machine includes hydraulic cylinders that make a working part ascend and descend; a first main pump that suctions oil from an oil tank and discharges the oil; an accumulator that accumulates oil discharged from weight holding side oil chambers of the hydraulic cylinders when the working part descends; and a hybrid pump that suctions accumulated oil pressure in the accumulator and discharges the oil pressure. When the working part ascends, discharged oil from the hybrid pump is supplied to the weight holding side oil chambers of the hydraulic cylinders. When an insufficient supply flow from the hybrid pump to the hydraulic cylinders exists, a complementary flow corresponding to the insufficient supply flow is supplied from the first main pump to the weight holding side oil chambers of the hydraulic cylinders.

Abstract: The present invention relates to a method and a device for monitoring a brake system for motor vehicles equipped with an electronic controlling and regulating unit, as well as a hydraulic pressure accumulator that is used as an auxiliary pressure source and subdivided by a media-separating element into two chambers, the first chamber being filled with a gas and the second chamber being filled with a liquid pressure medium. To conduct a reliable monitoring of the pressure accumulator, the invention provides that the number of the partial strokes of the media-separating element is detected. To this end, brake actuations are weighted and counted according to their duration and intensity. When the sum of the weighting factors reaches a predetermined number, a warning indicates an imminent damage to the media-separating element. This renders it possible to use a less costly and less sensitive media-separating element, which obviates the need for extensive protective measures against mechanical loads.

Abstract: A malfunction detection device of a bellows type accumulator for pressurized fluid includes malfunction judgment unit for judging a malfunction of the bellows type accumulator on the basis of a detection output of the pressure sensor. The malfunction judgement unit judges that the malfunction of the seal member generates when the difference between a peak pressure value appeared before a predetermined time is past after the starting of the pressure increase from a value below a predetermined value in the inlet and outlet port and a stable fluid pressure appeared after the appearance of the peak pressure value is not within a predetermined range and/or when the peak pressure value does not appear before the progress of the predetermined time.

Abstract: The present invention relates to a method of filling a pressure medium accumulator with a housing having an inner space that is subdivided into two chambers by a metallic pleated bellows used as a media-separating element, the first chamber thereof being filled with a gas and the second chamber being filled with a liquid pressure medium, and wherein a bottom valve is provided in a hydraulic port, its closing member being operable by the media-separating element, said valve permitting filling of the second chamber with fluid and preventing a complete evacuation of the second chamber. To enable reliable filling of the above-mentioned chambers with corresponding media without damaging the pleated bellows, the invention proposes a combination of the following process steps: a) evacuation of the second chamber b) filling of the second chamber with pressure medium, and c) filling the gas into the first chamber.

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: Pressure of a gas in a gas accumulator coupled to a fluid circuit is measured in a system involving separating gas from pressure fluid in a gas accumulator by a separating element, measuring pressure of the pressure fluid with a pressure detector coupled to the gas accumulator when the separating element is in a preadjustable position having a gas pressure assignable to it, detecting the preadjustable position by a monitor coupled to the pressure detector, and initiating measurement of the fluid pressure upon detection of the separating element in the preadjustable position.
