A device for fluid power recuperation with increased efficiency and safety may be used in stationary and mobile applications, such as road building machines, hoisting and conveying equipment as well as hydraulic hybrid vehicles. The device comprises at least one hydropneumatic accumulator communicating via its gas port with at least one gas receiver. The receiver is made in the form of an aggregate of cells communicating with the gas port of the accumulator via the collector, wherein the ratio of the receiver volume to the area of the cells internal surfaces does not exceed 0.01 m. At gas compression or expansion in the receiver the heat exchange between the gas and the cells walls occurs at reduced distances, with smaller temperature differentials, which increases reversibility of the heat exchange processes and recuperation efficiency. The aggregate of the receiver cells should be preferably embodied in a honeycomb structure where the partitions between the cells are connected with one another and the outer shell of the receiver. Taking some part of the load the partitions unload the outer shell, which allows making it less strong and massive and producing receivers of various shapes and dimensions ratio, thus facilitating integration of the device into the existing systems, including vehicles.
