A hydraulic accumulator is used for one of two purposes: either to add volume to the system at a very fast rate or to absorb shock. which function it will perform depends upon its pre-charge. if the accumulator is to be used to add volume to the system, its pre-charge must be somewhat below the maximum system pressure so oil can enter.
