    Tips: What is a hydraulic accumulator?

    A hydraulic accumulator is a device that stores hydraulic fluid under pressure, which can be used to power hydraulic systems. It consists of a pressure vessel and a piston or bladder that separates the hydraulic fluid from a gas or spring. When hydraulic fluid is pumped into the accumulator, it compresses the gas or spring, storing energy that can be used later to provide a burst of hydraulic power.
