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

Save Your Engine With Canton''s Accusump

The Accusump is simple and ingenious – it''s a reservoir divided into two sections by a piston. On one side, oil is accumulated, and on the other, trapped air acts as a spring to keep that oil under pressure. It''s totally self-regulating, with the oil side filling and emptying in response to the pressure in the engine''s oiling system.

This hydraulic energy is stored in a fluid, typically oil, that is compressed within the accumulator. The functioning of an accumulator is based on the principle of a piston and cylinder system. When pressure is applied to the fluid, the piston is forced downwards, compressing the fluid and storing the energy.


An oil accumulator is supposed to push oil to the system once the minimum pressure (the low pressure alarm + a margin) is reached. The required oil should be maintained for enough time (ideally 4+1 seconds), while the mid-pressure (pressure between the maximum and the minimum) is retained.
