System for detaching a cartridge carrier from a firearm

Abstract

System for detaching a carrier of a piece of ammunition (42) from a firearm, comprising: a carrier recuperator (60), which includes: a first and a second cylinder (111, 112) comprising, respectively, a first and a second piston (63, 67); wherein each piston (63, 67) defines, in the respective cylinder (111, 112), a primary chamber (16, 66) filled with liquid, and the two primary chambers (16, 66) are in fluid communication with each other to allow a flow of liquid;The second piston (67) defines, in the second cylinder (112), a secondary chamber (68) containing a return means for moving the second piston (67) and pumping the fluid into the primary chamber (16) of the first cylinder (111). The system includes a carrier reloading transmission comprising: a first and a second articulated connecting rod (142, 143) articulated to a fulcrum (158), wherein the first connecting rod (142) is also articulated to a recoil mass (8) of a firearm; a straight guide (137, 138) on which the articulated connecting rods (142, 143) are intended to rest and slide; a reloading lever (93) freely rotatable about a first axis of rotation (153), and having a slider (154) at a first end thereof;a slotted linkage lever (62) rotatable about a second axis of rotation (21), and having a guide in which the slider (154) of the reloading lever (93) is slidably mounted, wherein the first piston (63) is connected to the slotted linkage lever (62) such that the movement of the first piston (63) is limited to the rotation of the slotted linkage lever (62); a crank lever (144, 148), rotatable about the first axis of rotation (153), having a first end connected to the recoil mass via the two articulated connecting rods (142, 143), and configured to interfere with the rotation of the reloading lever (93); a release transmission configured to guide the movement of the carrier (114) and to selectively hold in position and release the reloading lever (93);wherein the first piston (63) is connected to the release transmission in such a way that it limits the movement of the first piston (63) to a movement of the carrier (114).;
