Definitions

  • the present invention relates to a rear block for an automatic weapon actuated by recoil from the barrel.
  • Such weapons are equipped with a device known as rear block, intended to brake and stop the barrel at the end of recoil and to return it to its initial advanced position.
  • this rear block in fact determine 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.
  • the invention provides a rear block of the type comprising a buffer associated with an elastic damping and return means, characterized by a second damping stage comprising a thrust cone, intended to be engaged by said buffer during from its recoil movement, this cone engaging a radially expandable ring and axially mobile, this ring itself engaging elastic means, means being provided for adjusting the distance separating said pad and said 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 then returned forward (towards the left of said figures) by a rear block 4, object of the invention.
  • This block 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 washers 9 constitute a first damping stage and 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.
