    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 can a  hydraulic bladder accumulator store?

    A hydraulic bladder accumulator can store pressurized fluid, usually hydraulic fluid, in the flexible bladder. The bladder separates the pressurized fluid from the gas side of the accumulator. The amount of fluid that can be stored in a hydraulic bladder accumulator depends on the size and capacity of the accumulator. Hydraulic bladder accumulators can be used to store energy, absorb shocks and pressure spikes, and provide a ready supply of pressurized fluid when it is needed in hydraulic systems. It should be noted that the working medium of the ATO hydraulic bladder accumulator can only be hydraulic oil and nitrogen.
