Piston-Type Accumulator. This accumulator consists of a cylinder
assembly, a piston assembly, and two end-cap assemblies. The cylinder assembly
houses a piston assembly and incorporates provisions for securing the end-cap
assemblies. An accumulator contains a free-floating piston with liquid on one
side of the piston and precharged air or nitrogen on the other side . An
increase of liquid volume decreases the gas volume and increases gas pressure,
which provides a work potential when the liquid is allowed to discharge.
