Hydropneumatic suspension is a type of motor vehicle suspension system, invented by Paul Magès, produced by Citroën, and fitted to Citroën cars, as well as being used under licence by other car manufacturers. Similar systems are also widely used on modern tanks and other large military vehicles.
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 ...

Hydropneumatic water hammer preventers are chambers of sufficient volume to allow an extension of time in which a given flow may be accelerated or decelerated without sudden large change in pressure. See also expansion tank. When shock waves of an incompressible fluid within a piping system exist, especially at a high velocity, there is a high ...
The early version tanks (retroactively designated Strv 103A) were soon upgraded to B-standard. Adjustments to the hydro-pneumatic suspension increased elevation range from −10 through +12 degrees, to −11 through +16 degrees. [19] Stridsvagn 103C An upgrade programme was started in 1986 to fit all vehicles with improved fire control systems.
Water was pumped to a tank at the top of these towers by steam pumps. When dock machinery required hydraulic power, the hydrostatic head of the water's height above ground provided the necessary pressure. These simple accumulators were extremely tall. For instance, Grimsby Dock Tower, built in 1852, is 309 feet (94 m) tall. Because of their ...
A disadvantage of the torsion bar suspension used in Tiger and Panther tanks (and many other WWII-era tanks and other AFVs) was the inability to incorporate an escape hatch through the bottom of the hull, a common feature of WWII-era tanks, as the torsion bar arrangement would have blocked crew access to such a hatch; however, the absence of ...
Oil tankers generally have from 8 to 12 tanks. [1] Each tank is split into two or three independent compartments by fore-and-aft bulkheads. [1] The tanks are numbered with tank one being the forwardmost. Individual compartments are referred to by the tank number and the athwartships position, such as "one port", "three starboard", or "six ...
