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 hydraulic fluid reservoir (10, 10′, 10″, 10′″) comprises a body 12, 12′, 12″ 12′″) defining a variable volume chamber having one end portion movable with the level of fluid in the chamber. A biasing member (18, 18′, 18″, 18′″) acting on a traction rod (16, 16′, 16″, 16′″) extending from the movable end portion restrains movement thereof under fluid pressure. The fluid pressure in the variable volume chamber advantageously counterbalances the force of reaction in the biasing member (18, 18′, 18″, 18′″).

Abstract: 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.

Abstract: Accumulator device for a hydraulic installation which includes an interior membrane, the membrane forming a fluid-accumulation cavity. It is characterised in that the membrane includes a fold which forms two sections, a first section from the wall of the cylindrical body to the fold and a second section from the fold to the moving support element, with the fold zone moving as the moving support element moves. It allows sufficient volumes of water accumulation to space apart the starting and stopping of the electrically-driven pump, but with small diameters of the membrane's moving support element.
