FIELD: construction.
SUBSTANCE: invention relates to construction equipment. Working machine, excavator, in particular, or machine for loading, unloading and transportation of materials has element made movable by means of at least one working hydraulic cylinder. There is at least one cylinder of energy recovery for energy recovery of moving element. Energy recovery cylinder has a chamber filled with gas and located in functional connection with pressure accumulator, which prevents rise of pressure in the chamber filled with gas, starting, at least, from maximum pressure. Pressure accumulator is connected via pipeline on liquid medium with a chamber filled with gas, wherein, pressure accumulator is connected to the cylinder of energy recovery, or pressure accumulator is integrated into cylinder of energy recovery.
EFFECT: technical result is improvement of operation of working machine energy recovery system.
