Accumulators come in a variety of forms and have important functions in many hydraulic circuits. They are used to store or absorb hydraulic energy. When storing energy, they receive pressurized hydraulic fluid for later use. Sometimes accumulator flow is added to pump flow to speed up a process.

In mechanical and industrial engineering, an accumulator is a pressure vessel that stores hydraulic fluid under pressure so it can release energy on demand. Think of it like a battery for a hydraulic system. When the system generates more pressure than it needs, the accumulator absorbs the excess.
What is an Accumulator Used For? Accumulators perform several critical functions in industrial settings: Energy Storage: Store hydraulic energy for a quick release when the system needs high power. Shock Absorption: Reduce vibration and pressure spikes to protect machinery.
An accumulator is an energy storage device: a device which accepts energy, stores energy, and releases energy as needed. Some accumulators accept energy at a low rate (low power) over a long time interval and deliver the energy at a high rate (high power) over a short time interval.
Essentially, an accumulator is a vessel containing a bladder and gas so that as the bladder fills with pressurized hydraulic fluid, the gas compresses inside the vessel. When the fluid in the accumulator is released, the compressed gas pushes out the fluid.
