Hydraulic accumulators: how do they work?
A piston accumulator is much like a hydraulic cylinder without a rod. Similar to other accumulators, a typical piston accumulator consists of a fluid section and gas section, with the movable piston separating the two. Less common are piston accumulators that replace high-pressure gas with a spring or heavy weight to apply force to the piston.
What are Hydraulic Accumulators?
