Hydraulic accumulators store energy and regulate hydraulic system performance. They are pressurized storage reservoirs where an external force such as compressed gas holds hydraulic fluid under pressure. Types of hydraulic accumulators include piston, bladder, and diaphragm. All three types consist of a two-chambered cylinder where one side holds the hydraulic fluid and the other side holds the compressed gas used to pressurize the fluid. Depending on the type of accumulator, the two chambers are separated by a floating piston, a bladder, or an elastic diaphragm. Hydraulic accumulator accessories improve the accumulator’s functionality. They include bladder pull rods, safety blocks, mounting hardware, and repair kits.
