"Hydro" because a liquid (like water) is involved. "Pneumatic" because a gas (like air) is involved. "Accumulator" because the purpose is to store or accumulate liquid volume by easy compression of the gas. These devices are typified by having only one liquid connection that goes to a "T" on the system.
The usual recoil system in modern quick-firing guns is the hydro-pneumatic recoil system. In this system, the barrel is mounted on rails on which it can recoil to the rear, and the recoil is taken up by a cylinder which is similar in operation to an automotive gas-charged shock absorber , and is commonly visible as a cylinder mounted parallel ...
The principles illustrated by the successful use of hydropneumatic suspension are now used in a broad range of applications, such as aircraft oleo struts and gas filled automobile shock absorbers, first patented in the U.S. in 1934 [31] by Cleveland Pneumatic Tool Co. Similar systems are also widely used on modern tanks and other large military ...
[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.
It is a method of converting hydraulic power to pneumatic power. [1] this type of hydraulic compressor is used in various applications where hydraulic power is already available and a relatively small amount of compressed air is needed, as it is not very efficient compared to an electrically driven compressor.

Paul Ernest Mary Magès (1908–1999) is known for his invention of the first self-leveling automobile suspension, known as hydro-pneumatic suspension. This system replaced conventional steel springs with an adaptive system of hydraulic struts, resulting in a motoring experience that felt like no other automobile of the era. [1] [2]
[clarification needed] They were used on board ships where a constant pressure hydraulic system extended through the whole ship, especially to control ball valves [clarification needed] but also to help drive the steering gear and other systems. The advantage of the screw pumps is the low sound level of these pumps; however, the efficiency is ...
The system dubbed Magic Body Control is fitted with a road-sensing system (Road Surface Scan) that pre-loads the shocks for the road surface detected. Using a stereo camera , the system scans the road surface up to 15 meters ahead of the vehicle at speeds up to 130 km/h (81 mph), and it adjusts the shock damping at each wheel to account for ...
