Piston Accumulators

Using an accumulator as an energy storage device effectively reduces the required flow rate capacity of the hydraulic pump, this results in a reduction of the installed power.
The energy stored in an accumulator is used to avoid the accidental interruption of the working of the power generator by guaranteeing continuity of the safety function for a specific time.
An accumulator which is kept constantly under pressure allows for instant and/or repetitive operations as required (braking, opening of doors etc).
An accumulator on account of the low inertia of its bladder can dampen the pulsations generated by the pump.
