What does an accumulator do in a hydraulic system?
In a hydraulic system, an accumulator stores and releases fluid to maintain system pressure and compensate for changes in fluid volume. Most accumulators don’t require any input signals from the control system directly—the fluid is usually piped directly into and out of the accumulator. A hydraulic control system directs the flow of fluid to different devices within the system.
What are the common problems with accumulators?
