Abstract

Cloueuse pneumatique utilisant du CO2, dans laquelle une vis de connexion est couplée à un piston secondaire dans un carter de la cloueuse et une extrémité arrière du carter est couplé à un siège de marteau. Un élément de retenue est introduit dans une chambre interne d'une extrémité avant du carter. De plus, un joint mobile est introduit dans un trou situé dans l'élément de retenue, un ressort étant placé entre l'élément de retenue et le joint. Un commutateur est placé dans une chambre du joint. Une plaque de couverture frontale peut être fixée dans un cylindre externe et un piston principal est situé à l'avant d'un cylindre interne. Le piston principal est situé à droite d'un percuteur. Ledit piston secondaire est placé dans le cylindre externe. Un déclencheur dont l'extrémité avant est en contact avec le percuteur est situé au-dessus d'une partie saillante vers le bas du commutateur. Un orifice d'entrée est vissé dans un conduit de transition. Un cylindre de gaz est situé entre le conduit de transition et l'orifice d'entrée. La cloueuse selon la présente invention repose sur l'utilisation de CO2 en tant que source de puissance, sans qu'il soit nécessaire d'avoir recours à l'électricité et à de l'air comprimé. Par conséquent, elle peut être utilisée de manière mobile; en outre, elle est peu bruyante et possède de bonnes performances d'étanchéité.
