    Abstract: A dual piston accumulator, in particular for a hydrostatic hybrid drive system for vehicles, replaces a high pressure hydro accumulator and a low pressure hydro accumulator. Inside a single accumulator housing (2) extending in the axial direction in a single piece over a high pressure part (4) and a low pressure part (6), an accumulator piston (8, 10) defines a high pressure-sided fluid chamber (16) and a low pressure-sided fluid chamber (18). Both chambers border an intermediate piece (12) separating the high pressure side (4) from the low pressure side (6). A common piston rod (14) extends through the intermediate piece for both accumulator pistons (8, 10). The wall width of the housing (2) corresponding to the high pressure part (4) is greater than the opposite reduced wall width corresponding to the low pressure part (6).

    Abstract: Examples described herein relate to compact and replaceable accumulator to be utilized in a chassis-level cooling device. The accumulator is a low pressurized device having a housing, a bladder, and a compressible fluid. The housing has an inner surface defining a volume and an opening. The bladder is disposed within a volume portion and attached to the opening. The bladder includes a plurality of elongated wall sections foldably coupled to each other and defining a bladder volume therebetween. The bladder inflates by unfolding the plurality of elongated wall sections to increase the bladder volume in response to an increase in a pressure of a working fluid inside the bladder volume. The compressible fluid is contained in a remaining volume portion between the inner surface of the housing and the bladder. The compressible fluid is compressed to an offset pressure in response to inflation of the plurality of elongated wall sections.

    Abstract: A method of charging a hydro-pneumatic energy storage system is described. The system has a first hydro-pneumatic accumulator with a first hollow vessel. Disposed within the first hollow vessel is a first compressible volume containing a first amount of gas. The system has a second hydro-pneumatic accumulator with a second hollow vessel. Disposed within the second hollow vessel is a second compressible volume containing a second amount of gas. The gas contained in the first volume is pre-pressurized to a first hydrostatic pre-charge pressure and the gas contained in the second volume is pre-pressurized to a second hydrostatic pre-charge pressure. The second pre-charge pressure is higher than the first pre-charge pressure. In addition, the gas in the first volume is pressurized by discharging a non-compressible hydraulic fluid into the first vessel while keeping a quantity of non-compressible hydraulic fluid contained in the second vessel constant to keep the pressure of the gas contained in the second volume at the second pre-charge pressure.

    Abstract: The present invention is a distributed piston elastomeric accumulator which stores energy when its elastomeric member stretches from its original length in response to the flow of a pressurized fluid. The stored energy is returned when the fluid flow is reversed and the accumulator discharges the fluid as its elastomeric member returns to its original length and moves the piston to its initial position. At least one part of the novelty of the invention is that the accumulator is not subject to radial strain gradients and the accumulator allows for precise pressure and linear position measurements. Accordingly, the invention allows for optimization of the energy strain storage capacity of a given elastomer.

    Abstract: An open port is provided on an inner peripheral surface of the cylinder bore of the reservoir apparatus and the port is exposed to the exterior of the reservoir apparatus. A hollow portion is formed concentrically with the port on a reservoir body. An annular thin portion is formed between the inner peripheral surface of the cylinder bore and the hollow portion surrounding the port in a radial direction. The thin portion is outwardly deflected and deformed by being pushed outwardly in a radial direction centering on the port in a range narrower than the inner diameter of the hollow portion. Thus, the opening of the port is outwardly sunk from the inner peripheral surface of the cylinder bore thereby to form a curved surface at a root portion of the thin portion on the inner peripheral surface of the cylinder bore.
