How the term is used
An accumulator can damp pressure fluctuations, provide emergency or peak-demand flow and maintain pressure for selected functions. A gas precharge is separated from hydraulic fluid by a bladder, piston or diaphragm.
Where you may encounter it
Technicians use approved procedures for depressurization, precharge checks and servicing.
Stored hydraulic and gas pressure can remain after system shutdown. Verify complete isolation before maintenance.
