Accumulator Definition:
An accumulator is a pressure vessel in which fluid is stored.
Typically, an accumulator contains a compressible gas, a separator
(i.e. piston, bladder diaphragm, etc.), and an incompressible
hydraulic fluid. The compressible gas behaves much like a
spring, which allows energy to be stored and dissipated, while
the separator transfers these changes in energy and volume
to the hydraulic fluid. Accumulators help designers control
the power and flow-rates of hydraulic circuits.
