The invention relates to a device for feeding ball-like ammunition, so-called paint balls, into the projectile chamber of a sporting arm (1). The magazine (3) is arranged separately from the arm (1) and is connected to same by means of a feeder tube (2). A motor-driven feeder (8) feeds the balls (14) from the ball container (3) into the feeder tube (2). In so doing, a spring element (17) stores the traction from the motor, so that, even when the motor stops, balls (14) can still be transported using the energy stored in the spring element (17). The traction from the motor is transmitted via a connection or clutch consisting of a spring element (17)and a transmission element (19). Protrusions (20,21) are arranged on both the spring element (17) and the transmission element (19),wich come to bear on each other for transmitting traction. The protrusions (20,21) are at least partially flexible, so that the transmitted force is limited. This way, explosions of the balls (14) from excessive pressure is prevented. In addition, the feeder (8) is connected with the drive element (16) for the feeder (8)which is under pressure from the spring, by means of a bayonet-like connection. This way, the feeder (8) can be removed from the ball container (3) with one manipulation to facilitate the cleaning of the ball container (3) in the event a ball (14) explodes in spite of this.

L'invention concerne un dispositif d'alimentation de munitions de type billes, désignées sous le nom de billes de peinture, dans le chargeur d'une arme (1) utilisée dans certains sports. Le magasin (3) est séparé de l'arme (1) et est connecté à celle-ci au moyen d'un tube (2) d'alimentation. Un dispositif (8) d'alimentation commandé par un moteur insère les billes (14) du magasin (3) dans le tube (2) d'alimentation. Un élément (17) à ressort stocke la traction du moteur de façon que les billes (14) puissent être transportées, y compris si le moteur est arrêté, à l'aide de l'énergie stockée dans l'élément (17) à ressort. La traction du moteur est transmise via une connexion ou embrayage formés d'un élément (17) à ressort et d'un élément (19) de transmission. L'élément (17) à ressort et l'élément (19) de transmission comprennent des saillies (20, 21), et sont associés l'un à l'autre pour transmettre la traction. Lesdites saillies (20, 21) sont au moins partiellement flexibles de façon à limiter la force transmise. On évite ainsi l'explosion des billes (14) due à une pression excessive. Le dispositif (8) d'alimentation est, de plus, connecté à un élément (16) de commande du dispositif (8) d'alimentation qui est sous la pression du ressort, par une connexion de type baïonnette. Le dispositif (8) d'alimentation peut ainsi être retiré du magasin (3) à billes en une seule manipulation pour faciliter le nettoyage dudit dispositif (3) au cas où une cartouche (14) exploserait.
