Abstract
Dispositif de percussion entraîné par du liquide comprenant un carter (1) et un piston percuteur (2) pouvant se déplacer avec un mouvement de va-et-vient dans ce dernier. Le piston-percuteur est pourvu de canaux (8) qui servent, lorsque le piston percuteur passe en position de percussion (2), à envoyer du liquide sous pression à un corps (9) de soupape pour verrouiller ce dernier afin d'apporter en continu du liquide sous pression sur une première surface (4) située sur le piston percuteur (2) et à un canal (6) de lavage pour laver en continu un trou de forage.
