摘要： A fill cap assembly for a transmission is provided. In one form, the fill cap assembly includes a first part and a second part, each defining a cavity therein. A flexible membrane is disposed between the first and second parts and separates the cavities of the first and second parts. The cavities are sealed from each other by the membrane. The cavity of the first part is configured to be in fluid communication with the inside of the transmission. When pressure rises in the transmission, the flexible membrane expands into the cavity of the second part. When pressure sinks in the transmission, the membrane collapses partially into the cavity of the first part, thus expanding out of and/or away from the cavity of the second part.

摘要： The invention relates to a fluid power accumulator in which the fluid undergoes a state change as the system is pressurized to store energy. A state change can be a phase change, a chemical reaction, or a combination of these. Generally the state change results from the interaction of a compressible fluid contained in the accumulator with another substance, which can be a fluid or a solid. Preferably, the state change includes the physical adsorption of a fluid by a solid adsorbant. The invention can improve the energy storage density of a fluid power accumulator, allow a given energy storage density to be achieved at a lower maximum pressure, facilitate heat transfer and storage within an accumulator, and/or improve accumulator efficiency by storing energy in a form other than thermal energy, such as in the form of chemical energy.

摘要： 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′″).

摘要： 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.

摘要： A method monitors the gas prefill pressure in hydraulic accumulators. After the pressure supply to the oil side of the accumulator has been interrupted and the contents of the tank have been emptied, the current gas temperature and the current gas pressure are determined, once the temperature has equalized. The data relating to the gas temperature and pressure is telemetrically transmitted to an evaluation unit, which is spatially located at a distance, to calculate an actual value of the gas prefill pressure which corresponds to a reference temperature.
