A rounded vessel storing energy under pressure.
Also known as: Pressure accumulator, Gas-loaded accumulator
An accumulator stores hydraulic energy under pressure, drawn as a rounded vessel with an internal division showing whether it is gas-loaded, spring-loaded or weight-loaded. It stays charged after a system is switched off, which makes it the reason a hydraulic circuit can be dangerous when apparently dead.
Stores fluid under pressure for later release, drawn as a rounded vessel with a division showing the loading method.
Contexts: Technical drawing
Retains its stored energy after the pump stops, so a circuit with an accumulator can remain pressurised and dangerous when switched off.

An outline shaped like a rounded-ended cylinder standing upright, divided across its middle by a line or a curve.
