FIELD: machine building.
SUBSTANCE: invention relates to machine building and can be used in various hydraulic drives of load-lifting both stationary and mobile agricultural, construction and road machines and equipment, as well as in machine building, oil and mining industry. Device for compressed air accumulation comprises main and additional receivers, pneumatic cylinders installed parallel to hydraulic cylinders, pressure pneumatic line, controlled reduction pneumatic and reverse pneumatic valves, pneumatic motor, hydraulic pump, pneumohydraulic accumulator, additional hydraulic pump, at that serial connection of receivers at their charging and discharge is performed automatically.
EFFECT: higher efficiency of energy accumulation in energy-saving pneumatic and hydraulic drives of machines.
