Device for fluid power recuperation

Apparatus comprising:

• a regenerating heat exchanger for a gas receiver of a fluid power recuperator, wherein the regenerating heat exchanger is configured to receive heat generated by gas in the gas receiver from the transfer of energy from the fluid power transfer system to the fluid power recuperator,
• wherein the fluid power recuperator includes at least one hydropneumatic accumulator, wherein the accumulator includes a fluid reservoir and a gas reservoir, wherein the accumulator includes a shell, wherein the shell contains a fluid port, wherein the fluid port communicates with the fluid reservoir, wherein the fluid port is configured to be operatively connected to a fluid power transfer system, wherein the fluid reservoir is separated from the gas reservoir by a movable separator, wherein the accumulator includes a first gas port, wherein the first gas port communicates with the gas reservoir,
• wherein the gas receiver includes a second gas port, wherein the first gas port of the accumulator communicates with the second gas port of the gas receiver,
• wherein the regenerating heat exchanger is configured to return heat to the gas in the gas receiver which causes fluid power to return to the fluid power system when energy returns from the fluid power recuperator into the fluid power system,
• wherein an aggregate area of heat exchange surfaces of the regenerating heat exchanger over an aggregate internal receiver volume is greater than 2000 cm2/liter.

Apparatus comprising:

• a gas receiver for a fluid power recuperator including:
• a receiver shell, wherein the receiver shell includes a receiver interior area,
• a first gas port fluidly connected with the receiver interior area, wherein the fluid power recuperator includes at least one hydropneumatic accumulator, wherein the accumulator includes a fluid reservoir and a gas reservoir, wherein the accumulator includes an accumulator shell, wherein the accumulator shell is separate and disposed away from the receiver shell, wherein the shell contains a fluid port, wherein the fluid port communicates with the fluid reservoir, wherein the fluid port is configured to be operatively connected to a fluid power transfer system, wherein the fluid reservoir is separated from the gas reservoir by a movable separator, wherein the accumulator includes a second gas port, wherein the second gas port communicates with the gas reservoir, wherein the first gas port is configured to communicate with the second gas port of the accumulator;
• and
• a regenerating heat exchanger, wherein the regenerating heat exchanger includes components that comprise a structure, wherein the components of the regenerating heat exchanger structure are loaded inside the receiver interior area through the first gas port of the gas receiver, wherein the regenerating heat exchanger is configured to receive heat generated by gas in the gas receiver from the transfer of energy from the fluid power transfer system to the fluid power recuperator, wherein the regenerating heat exchanger is configured to return heat to the gas in the gas receiver which causes fluid power to return to the fluid power system when energy returns from the fluid power recuperator into the fluid power system.
