Hydraulic Accumulators | Working | Types | Applications

During its work, the hydraulic pump raises the pressure of the system and forces the fluid to enter the accumulator. Valves are used to control the flow of oil in and out. The piston or bladder moves and compresses the volume of the gas because fluid pressure exceeds the older pressure. This is the source of the stored energy that is to be used.
