The pneumatic projectile launcher contains a working cylinder (101) with a piston (103) movable under the influence of gas pressure under the piston, between a starting position in the rear section of the working cylinder and a firing position in the front section of the working cylinder (101) for a passage of a projectile (10) mounted above the piston (103) in the direction of the shot, a breech securing the piston (103) in a starting position and a trigger connected through a control mechanism with the breech, whereas the working cylinder (101) closed in the rear section, has one end firmly mounted in the front head (110) with an axial opening (112) for the passage of the projectile (10) and the other end positioned in the rear head (141), both of which are firmly mounted in the case (50), whereas the space under the piston (103) is connected to the expansion chamber (51) created between the working cylinder (101), the wall of the case (50), the front head (110) and the rear head (141) and the breech is created by a flat brace element (162) with an opening (163) for the passage of the projectile (10) or the piston rod (104) of the piston (103), the flat brace element arranged from one side of the working cylinder (101) for arching the flat brace element (162) in the starting position of the projectile (10) or the piston rod (104) at the limit stop (164) connected to the case (50). The projectile (10) of the pneumatic projectile launcher is created by a shank (521) terminated at the front part by a point (511) and at the rear part by a foot (525), whereas the stabiliser (541) is slide mounted by its hub (542) on the shank (51) between the front position defined by the front axial limit stop (512) and the rear position defined by the foot (525), a slide-mounted flexible binding ring (531) is push fitted on the shank (521) between the stabiliser (541) and the foot (525) for braking the inertial movement of the stabiliser (541) during the flight of the dart projectile and a circumferential notch (523) is created in front of the foot (525) for intercepting a flexible binding ring (531), the binding ring (531) in the circumferential notch (523) at least partially overlapping the hub (542). |
