Abstract

Cette machine est du type de celles comportant une masse de frappe 4 constituée par un piston à double effet animé d'un mouvement alternatif agissant sur un outil 6 qui, chargé de transmettre l'énergie cinétique contenue dans la masse de frappe au sommet de l'impact jusqu'au point où cette énergie sera utilisée par le moyen d'une onde de choc, présente une collerette 7 destinée à venir en appui sur une butée 5 montée dans le bâti de la machine Selon l'invention, cette butée 5 est constituée par une pièce tubulaire traversée au moins partiellement par l'outil, et sur une extrémité de laquelle celui-ci prend appui, une chambre annulaire il remplie d'un fluide sous pression étant ménagée entre l'autre extrémité de la butée et le bâti de la machine.
