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 pump controllers provide a Means of control for multiple fixed delivery volume, low cost low complexity pumps; to provide variable flow as required by small (say +/- 10 psi) pressure increase or decrease of a system. Means of control for pump unloading / recirculation against no pressure, without electric pressure switches.
This compressor pumps the air into a flexible bellows, usually made from textile-reinforced rubber. The air pressure inflates the bellows, and raises the chassis from the axle. Electronic Air Suspension (EAS) is the air suspension system installed on the second version of the Range Rover. Five suspension heights are offered by this system.
[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 hydrostatic test involves pressurising the cylinder to its test pressure (usually 5/3 or 3/2 of the working pressure) and measuring its volume before and after the test. A permanent increase in volume above the tolerated level means the cylinder fails the test and must be permanently removed from service. [3]: sect. 5.7.3
PS: The Preventive Maintenance Monthly, more commonly referred to as PS Magazine, was a series of United States Army pocket-sized bulletins published between June 1951 and November 2019 as a monthly magazine with comic book-style art to illustrate proper preventive maintenance methods, as well as proper supply procedures and related safety.
The M-46 saw extensive combat service with the People's Armed Forces for the Liberation of Angola (FAPLA) during the Angolan Civil War and South African Border War. [9] From the mid to late 1970s Angolan M-46s were deployed with some success in the counter-battery role against South African artillery units, which possessed comparatively short ...
The SU-76 was an assault gun mounting the ZiS-3 on the chassis of a T-70 light tank. More than 14,000 were produced between 1942 and 1945. The Romanian TACAM R-2 tank destroyer was a R-2 tank converted to mount the ZiS-3 in a three-sided fighting compartment.
