ABSTRACT:
An improved counter-recoil dampening and braking mechanism for a machine cannon. The mechanism includes a cylinder which is secured to the gun barrel or housing of the machine cannon. A stationary piston is mounted inside the cylinder and has a pair of hollow piston rods extend in opposite axial directions from the stationary piston and respectively divides the cylinder into front and rear chambers. A front and rear end wall closes respectively the cylinder at its front and rear end wall. The front and rear hollow piston rods are respectively slidably disposed in the front and rear end walls of the cylinder. The front hollow piston rod is operatively secured to the cradle of the machine cannon. A flying piston is slidably disposed in the front hollow piston rod. The stationary piston has a first passage which coacts with a cover in the rear chamber to permit the flow of hydraulic fluid rearwardly during recoil; the cover sealing the first passage during counter-recoil. The stationary piston further having a first and a second throttling nozzle which coacts with the flying piston to permit the flow of hydraulic fluid forwardly from the rear chamber into the front chamber, so that first a strong braking action and then a reduced braking action is exerted on the cylinder during counter-recoil.
