"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.
[1] 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 ...
[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.
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 ...
[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 ...
"Whatever stage of your life, whatever age, whatever size, we have to love every inch and own every part of ourselves,” said Long, per a SKIMS press release
The other type of hydraulic compressor uses potential and kinetic energy of a stream of water to entrain air ad carry it to a separating chamber at a higher pressure where the air accumulate above the water, and the water is allowed to drain, The system has few if any moving parts, and is also inefficient, so is used where kinetic or potential ...
