    Hydraulic bladder accumulator is a type of hydraulic accumulator that use a flexible bladder to separate gas and hydraulic fluid, widely used in hydraulic systems in aerospace, automotive, marine industries and industrial applications.

    hydraulic accumulator applicationsTips: What is a nitrogen accumulator?

    A nitrogen accumulator is a type of hydraulic accumulator that uses compressed nitrogen gas to store hydraulic fluid under pressure. It works on the same principle as a hydraulic accumulator, with a pressure vessel and a piston or bladder that separates the hydraulic fluid from the compressed nitrogen gas. When hydraulic fluid is pumped into the accumulator, it compresses the nitrogen gas, storing energy that can be used later to provide a burst of hydraulic power.
