    Abstract: The invention relates to systems and methods for rapidly and isothermally expanding gas in a cylinder. The cylinder is used in a staged hydraulic-pneumatic energy conversion system and includes a gas chamber (pneumatic side) and a fluid chamber (hydraulic side) and a piston or other mechanism that separates the gas chamber and fluid chamber while allowing the transfer of force/pressure between each opposing chamber. The gas chamber of the cylinder includes ports that are coupled to a heat transfer subassembly that circulates gas from the pneumatic side and exchanges its heat with a counter flow of ambient temperature fluid from a reservoir or other source.

    Abstract: A plunger pressure accumulator includes a shell; and a plunger which is adapted to move relative to the shell into an interior space of the shell. The interior space is divided into at least two subspaces, a first subspace of which is suppliable with hydraulic fluid of an external system and a second subspace which is provided with a pressurized gas. Between the plunger and the shell is arranged a slide element upon which the plunger is supported to move to a distance apart from an internal surface of the first subspace and from an internal surface of the second subspace. The plunger pressure accumulator is provided with at least one regenerator which is stationary relative to the shell or the plunger.

    Abstract: A device for fluid power recuperation with increased efficiency and safety may be used in both stationary and mobile applications including hydraulic hybrid vehicles.The device includes a hydropneumatic accumulator communicating via its gas port with a gas receiver. The receiver is made in the form of an aggregate of cells separated by partitions. The ratio of the receiver volume to the area of the cells internal surfaces does not exceed 0.01 m. Thermal capacity of the partitions exceed that of the gas at maximal pressure.This improves heat exchange between the gas and the cells walls at gas compression or expansion, which increases recuperation efficiency.A honeycomb structure where the partitions between the cells are connected with one another and the outer shell of the receiver allows making it less massive and facilitating integration of the device into the existing systems, including vehicles.

    Abstract: A device for fluid power recuperation with reduced heat losses and increased efficiency of fluid power recuperation combined with better manufacturability and possibility of using off-the-shelf gas receivers (bottles). The device comprises at least one hydropneumatic accumulator, containing in its shell a fluid port communicating with the fluid reservoir of the accumulator separated from the gas reservoir of the accumulator by a movable separator. The gas reservoir of the accumulator communicates via a gas port with at least one gas receiver containing a regenerating heat exchanger made in the form of a metal porous structure. The aggregate volume of the material of the regenerating heat exchanger is in the range from 10 to 50% of the internal receiver volume and the aggregate area of the heat exchange surfaces of the regenerating heat exchanger reduced to the aggregate internal receiver volume exceeds 2000 cm2/liter. At gas compression or expansion the heat exchange between the gas and the regenerating heat exchanger occurs at small average distances between the gas and the heat exchange surfaces and on a large heat exchange area, and, therefore, with smaller temperature differentials, which increases reversibility of the heat exchange processes and recuperation efficiency. The proposed device has the following properties:—reduced heat losses and increased efficiency of fluid power recuperation;—better manufacturability;—possibility of using off-the-shelf gas receivers of any type in the device.

    Abstract: A hydropneumatic accumulator includes a shell in which gas and fluid ports are connected, respectively, with gas and fluid reservoirs of variable volume separated by a movable separator. The gas reservoir contains a compressible regenerator that fills the gas reservoir so that the separator movement reducing the gas reservoir volume compresses the regenerator. The regenerator is made from leaf elements located transversally to the separator motion direction and dividing the gas reservoir into intercommunicating gas layers of variable depths. The regenerator is preferably made from interconnected elastic metal leaf elements to allow variation of the bending strain degree so that the local bending strains of the leaf elements should not exceed the elastic limits at any position of the separator. The efficiency of fluid power recuperation and durability of the regenerator are increased.

    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.
