CA 2354477

A power actuated tool for driving a fastener such as a pin into a substrate such as steel or concrete comprises a driving piston (6) which is driven forwardly within the barrel (4) of the tool upon firing and is automatically reset in response to cocking of the tool prior to the subsequent firing. Resetting of the piston takes place by thrusting the piston (6) rearwardly during cocking by means of a spring-loaded gripper device (14) energised during cocking.

L'invention concerne un outil à moteur destiné à enfoncer un élément de fixation, notamment une cheville, dans un substrat tel que de l'acier ou du béton. Cet outil comprend un piston d'enfoncement (6) qui est entraîné vers l'avant dans le tube (4) de l'outil lors de la décharge et est automatiquement remis en position initiale lorsque l'outil est réarmé avant la décharge suivante. La remise en position initiale du piston s'effectue par la poussée du piston (6) vers l'arrière au cours du réarmement au moyen d'un dispositif de préhension monté sur ressort (14) actionné pendant le réarmement.
