Abstract (en)

[origin: US2004250866A1] A pressure fluid accumulator with a housing having its interior 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, and wherein in a hydraulic port a bottom valve is provided which permits filling the second chamber with liquid and prevents complete evacuation of the second chamber, and the valve's closure member is operable by the media-separating element. In order to prevent, especially at low temperatures and high viscosity of the pressure fluid, damage of the media-separating element caused by a high differential pressure, a device is provided between the media-separating element and the bottom valve.
