DEVICE FOR HYDRAULIC POWER RECOVERY Russian patent published in 2010 - IPC F15B1/08 F16L55/04 

FIELD: machine building.

SUBSTANCE: device is designed for hydraulic power recovery in stationary and mobile mechanisms, such as road-building machines, handling machinery, and also for hydraulic hybrid motor cars. The device consists of at least one hydraulic-pneumatic accumulator communicating with at least one gas receiver via its gas port. The receiver corresponds to a plurality of cells communicating with the gas port of the accumulator via the collector; also ratio of receiver volume to area of internal surface of the cells does not exceed 0.01 m. At gas compression or expansion in the receiver heat exchange between gas and walls of cells proceeds along reduced distances with less drops of temperature which increases reversibility of heat exchange processes and efficiency of recovery. It is preferred to make the aggregate of the receiver cells in form of a cellular structure wherein partitions between the cells are interconnected and tied with an external shell of the receiver.

EFFECT: raised safety and reliability.
