[note 1] An accumulator enables a hydraulic system to cope with extremes of demand using a less powerful pump, to respond more quickly to a temporary demand, and to smooth out pulsations. It is a type of energy storage device. Compressed gas accumulators, also called hydro-pneumatic accumulators, are by far the most common type.
A simple control system for a water well. Referring to the figure on the left, a submersible water pump is installed in a well.The pressure switch turns the water pump on when it senses a pressure that is less than P lo and turns it off when it senses a pressure greater than P hi.
The coaster's power source is several hydraulic pumps, each capable of producing 500 horsepower (370 kW). These pumps push hydraulic fluid into several accumulators. These accumulators are divided into two compartments by a movable piston, one side filled with hydraulic fluid and the other with nitrogen gas. The nitrogen is held in large tanks ...
Hydropneumatic refers to the pneumatic (gas) and hydraulic (water) components needed for operation of the devices. Hydropneumatic accumulators or pulsation dampeners are devices which prevent, but do not absorb, alleviate, arrest, attenuate, or suppress a shock that already exists, meaning that these devices prevent the creation of a shock wave ...

The water jet system's cutting head restricts the water flow to generate pressure and direct it onto the workpiece. A holding tank, called a hydraulic accumulator, is used to reduce pressure vibrations at the output end. The more recently developed parallel hydraulic intensifier also uses oscillating pistons to compress water.
A typical subsea deepwater blowout preventer system includes components such as electrical and hydraulic lines, control pods, hydraulic accumulators, test valve, kill and choke lines and valves, riser joint, hydraulic connectors, and a support frame. Two categories of blowout preventer are most prevalent: ram and annular. BOP stacks frequently ...
Accumulator (cryptography), a value, determined by a set of values, that allows one to verify if any one of the original values is a member of the set; Accumulator (energy), an apparatus for storing energy or power Capacitor, in electrical engineering, also known by the obsolete term accumulator
