| 摘要 |
The present invention relates to a short recoil firearm (1) comprising a main body (2); a barrel (7) slidingly mounted on the main body (2) and movable between a forward percussion position and a backward recoil position; a slider (17) slidingly mounted on the main body (2) and movable between a forward position of closure of the barrel (7) and a backward stop position. The firearm (1) further comprises a plurality of cylindrical rollers (22) operatively connected to a spirally wound tape spring (26). The cylindrical rollers are movable between a first configuration, in which they lie mutually side by side between the slider (17) and the barrel (7), to prevent the relative movement thereof and to allow the integral displacement of same, and a second configuration, in which they lie in a recovery chamber (27). During passage from the first configuration towards the second configuration, the displacement of the barrel (7) opens an access (27a) for entrance of the cylindrical rollers (22) into the recovery chamber (27), causing disengagement between the barrel (7) and the slider (17). During passage from the second configuration towards the first configuration, the tape spring (26) brings the pushing elements (22) back to the first configuration through said access (27a). |
