Abstract: An accumulator for a hydraulic system includes a polymer liner defining a cavity. A metal bellows assembly is housed in the cavity and separates the cavity into a first chamber and a second chamber, with the first and second chambers isolated from one another by the bellows assembly. A composite shell substantially encases the liner. The liner and shell are configured so that the first chamber receives hydraulic fluid from and delivers hydraulic fluid through an opening in the liner and the shell as the bellows assembly expands and compresses due to pressurized gas in the second chamber balancing fluid pressure changes in the first chamber. In one embodiment, the metal bellows assembly includes hydroformed bellows.

Abstract: A hydropneumatic accumulator with a flexible porous filler intended for fluid power recuperation in hydraulic systems with a high level of pulsations includes a shell where a gas port and a fluid port are connected, respectively, with a gas reservoir and a fluid reservoir of variable volume separated by a movable separator. The flexible porous filler fills the gas reservoir so that the separator movement reducing the gas reservoir volume compresses said filler. The filler is connected with internal walls of the gas reservoir with the possibility of stretching the filler at the separator movement increasing the volume of the gas reservoir. The accumulator contains means of protection of the filler boundary layer against rupture made with the possibility of reducing local deformations of the boundary filler layer in case of jerks of the separator. Development of residual deformations of the filler during multiple recuperation cycles and destruction at non-uniform motion of the separator with strong jerks are prevented.

Abstract: 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.
