Definitions

  • the present invention relates to a breech damper for an automatic weapon actuated by the recoil of the barrel.
  • Such weapons are equipped with a device called a breech damper, intended to brake and stop the barrel at the end of recoil and to return it to its initial advanced position.
  • a breech shock absorber for a firearm is raised a.o. by American patent no. 2,802,401 which comprises a movable element supporting the barrel of a rifle associated with elastic damping and return means. These means include two springs in parallel and a braking device. Such a device has the drawback of causing very hard braking at the end of the travel of the movable element.
  • Shock absorbers are also known comprising two springs in series with different elasticity, as for example described in German patent no. 738,791. These shock absorbers have been specially designed for the damping of machine movements. They cannot be applied in a weapon, the transition from the damping of the first spring to damping of the second spring being made by a relatively hard shock.
  • German Patent No. 2,111. 126 also discloses a cylinder head damper comprising a single braking element as well as two parallel springs. This device has the disadvantage of not being adjustable.
  • breech damper determines the rate of fire, a function of the restitution of the recoil energy of the barrel.
  • the object of the invention is to allow the optimization of this restitution and, consequently, the adjustment of the rate of fire.
  • a bolt damper for an automatic reversing firearm comprising a buffer associated with a damping and deflection stage comprising elastic means, characterized by a second damping stage and deflection placed coaxially with respect to the first stage of shock absorber and deflection and in series with it and comprising elastic means as well as a thrust cone intended to be engaged by the buffer during its recoil movement, this cone of pushed, engaging a radially expandable and axially movable brake ring, this brake ring itself engaging the elastic means of the second damping and deflection stage, means being provided for adjusting the distance separating the pad and the thrust cone .
  • the machine gun shown diagrammatically in FIGS. 1 and 2 comprises a carcass 1 supporting a movable barrel 2 intended to push back a breech 3 in its recoil movement (FIG. 1), these movable parts being damped at the end of the race and then returned forward (towards the left of said figures) by a shock absorber ole cylinder head 4, object of the invention.
  • This damper 4 is constituted by a housing 5 (FIG. 3) comprising two chambers, respectively 6 and 7, separated by a partition 8 with a central opening.
  • the thrust cone 12 engages a radially expandable brake ring 15. Between the latter and the washers 14 is interposed a support washer 16. A threaded plug 17 engages a corresponding thread of the wall of the chamber 7.
  • the chamber 6 and the washers 9 constitute a first damping stage and the chamber 7 with the washers 14 a second stage.
  • the operation of the device is as follows.
  • the delay in the action of the ring 15 can be adjusted by adjusting the path A by means of the plug 17.
  • Figure 4 shows that, without a ring, the energy absorbed would be equal to the energy returned.
  • Figure 5 shows the action of the ring 15 for A equal to zero.
  • FIG. 6 finally represents the operation of the device represented in FIG. 3.
  • the hatched surfaces represent, from bottom to top, the energy restored by the first stage 9, that restored by the second stage 14 and, finally, the energy dissipated by the brake ring 15.
