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 pulsation filters provide means of reducing the amplitude of pressure changes the velocity of which is in the order of 1.4 km/s. All are used in industry. A hydropneumatic pulsation filter is a pressure container with separate inlet and outlet, connectable to a pipe system so that all pressure changes must attempt to pass through ...

Hydropneumatic suspension is a type of motor vehicle suspension system, invented by Paul Magès, produced by Citroën, and fitted to Citroën cars.The suspension was referred to as Suspension oléopneumatique [] in early literature, pointing to oil and air as its main components.
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 ...
The total volume of the tank is V t. Case 2 is a tank in use, with the air pressure at pressure P (gauge) and a water volume of V. Referring to the diagram on the right, a pressure tank is generally pressurized when empty with a "charging pressure" P c, which is usually about 2 psi below the turn-on pressure P lo (Case 1).
The last tank to use this basic mechanism was the Chieftain, designed in the late 1950s. Horstman Defence Systems remains a tank suspension specialist to this day and makes a range of systems based mostly on torsion systems with hydrodynamic damping. They are also referred to as "Horstman suspensions" although they have no details in common ...
The main armament of the 2S25 is a 125 mm smoothbore 2A75 tank gun, which is a derivative of the 125 mm 2A46 tank gun. [13] The angles of elevation and depression for the anti-tank gun are +15° and −5° respectively. When aimed towards the stern of the vehicle, the elevation and depression of the gun changes to +17° and −3° respectively. [4]
