Hydraulisk akkumulator – Wikipedia
En hydraulisk akkumulator er en tank med et gassvolum, ofte innkapslet i en blære, som fungerer som et "lager" for trykk. Ved sykliske arbeidsprosesser vil man bruke en akkumulator for å raskt kunne distribuere oljen som trengs. Man ønsker også å bruke en akkumulator for å fjerne forstyrrelser på linja, da fungere akkumulatoren som en demper.

BOOK 2, CHAPTER 1: Hydraulic Accumulators (part 2)
Fig-1-16. With an accumulator installed, as shown in Figure 1-17, the pump is still at no-flow when the circuit is at rest.However, there is a ready supply of oil at pressure available. As a cylinder starts to cycle, as seen in Figure 1-18, fluid flows directly to the actuator from the accumulator and pressure starts to drop.This pressure drop causes the pump to go on …
Hydraulic pump repeatedly start and stop reasons and solutions
According to the above control logic of the drive pump motor, it is not difficult to find that the cause of frequent start and stop of the pump motor is that the time of the system hydraulic oil pressure from the highest pressure value to the lowest pressure value is shorter, that is, the cycle is faster, then the reason for this cycle is ...

The start/stop function supported by the hydraulic impulse oil storage delivers an additional reduction in fuel consumption of up to another 5%, for an 11% overall reduction. When an engine stops under start-stop control, the transmission hydraulics are not supplied with pressure. In contrast to vehicles which stop with a running engine, the ...
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.

motor start/stop function. The thermal volume motor control insures that the accumulators fill completely or top out. This feature is critical in fail-safe applications where the stored hydraulic fluid is required to shut down valves in the event of electrical or power source failure.
What are Hydraulic Accumulators? How do They Work?
This reduces the requirement of a higher capacity pump and avoids a continuous start-stop cycle of the pumps. Uses of Accumulators: To supplement pump flow: As discussed earlier, the most common use for accumulators is to supplement pump flow. Certain machinery circuits require a high quantity of oil flow for a short time and then use little or ...
