Abstract (en)
[origin: US4824003A] An indirect firing fastener driving tool is provided including a barrel (51), a piston (6) sliding in the barrel for driving a fastener (3) housed in a fastener guide (7). Between the barrel (51) and the fastener guide (7) are disposed a rigid ring (22) and a resilient ring (24). Inside the resilient ring (24) is disposed a rigid ring (27) for limiting the stroke of the ring (22) intended to be received in a recess (25) provided at the rear part of the fastener guide (7). The head (14) of the piston is of a truncated cone shape and may cooperate with a bore (23) of corresponding shape in the rigid ring (22). The rings serve as absorber for the piston (6) whose stroke is thus controlled.
Abstract (fr)
L'appareil comprend un canon (51), un piston (6), coulissant dans le canon, pour entraîner un tampon (3) logé dans un guide-tampon (7). Entre le canon (51) et le guide-tampon (7) sont disposées une bague rigide (22) et une bague élastique (24). A l'intérieur de la bague élastique (24) est disposée une bague rigide (27) de limitation de la course de la bague (22). La tête (14) du piston est tronconique et peut coopérer avec un alésage (23) de forme correspondante dans la bague rigide (22). Les bagues servent d'amortisseur pour le piston (6) dont la course est ainsi contrôlée. L'appareil sert surtout au barbage de bâtiments.
