Understanding the Function of Accumulators

Accumulators come in a variety of forms and have important functions in many hydraulic circuits. They are used to store or absorb hydraulic energy. When storing energy, they receive pressurized hydraulic fluid for later use. Sometimes accumulator flow is added to pump flow to speed up a process. Other times the stored energy is kept […]

Hydraulic accumulator

Accumulator which stores a fluid under pressure and is therefore able to release hydraulic energy. Pressurisation is mainly based on gas pressure (air, nitrogen, "hydropneumatic accumulator") and, more rarely, springs or weights (spring accumulator, weighted accumulator).The latter is the only accumulator which keeps the pressure constant during withdrawal of the volume.

Hydraulic accumulator

A hydraulic accumulator is a pressure storage reservoir in which an incompressible hydraulic fluid is held under pressure that is applied by an external source of mechanical energy.The external source can be an engine, a spring, a raised weight, or a compressed gas. [note 1] An accumulator enables a hydraulic system to cope with extremes of demand using a less powerful pump, to …
