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.
