Energy transfer and conditioning

Reservoir, filter, cooling and accumulation that keep the fluid in good condition.

Reservoir (tank)

Open (vented) reservoir for hydraulic fluid. Open top = unpressurised reservoir.

ISO 1219-1

Filter

Removes particles from the fluid. Diamond with a dashed line = filter element.

ISO 1219-1

Cooler

Removes heat from the fluid. Diamond with outward-pointing arrows = heat is carried away.

ISO 1219-1

Accumulator

Stores energy as compressed gas acting on the fluid; smooths pressure surges and covers peak demand.

ISO 1219-1
