Illustration 2 g03661685The accumulator stores potential energy by accumulating a quantity of pressurized hydraulic fluid. The pressurized fluid is stored in a bladder type accumulator. A bladder that contains gas is located within the accumulator. The accumulator is charged with dry nitrogen.The pressurized hydraulic fluid enters the accumulator and the fluid creates pressure within the accumulator. Energy is stored as the bag that is within the accumulator is compressed by the hydraulic fluid. The pressurized hydraulic fluid that is stored in the accumulator permits the operator to lower the implements for a maximum of 1.5 minutes after the engine is turned off.
