The weight-loaded accumulator in Figure 16-1 does not lose pressure until the ram bottoms out. Thus 100% of the fluid is useful at full system pressure. The major drawback to weight-loaded accumulators is their physical size. They take up a lot of space and are very heavy if much volume is required.

The Basics. A hydraulic accumulator is a pressure vessel containing a membrane or piston that confines and compresses an inert gas (typically nitrogen).
Working of Hydraulic Accumulator: An accumulator usually has a cylindrical chamber, which has a piston in it. This piston is either spring loaded or some calculated weight is kept on it or even pneumatically pressurized. The hydraulic pump pumps the fluid into the accumulator, which is nothing but a sealed container.
