Olaer Accumulator

An accumulator is primarily used as a register in a CPU to store intermediate logical or arithmetic data in multistep calculations. For such calculations, it functions as a temporary storage location.A hydraulic accumulator is a pressure storage reservoir in which an incompressible hydraulic fluid is held under pressure that is applied by an external source of mechanical energy. The external source can be an engine, a spring, a raised weight, or a compressed gas.
