Title (EN) DOWN THE HOLE DRILLING MACHINE AND METHOD FOR DRILLING ROCK
(FR) MACHINE DE FORAGE DE FOND DE TROU ET PROCÉDÉ POUR FORER UNE ROCHE
Abstract:
(EN) A down the hole rock drilling machine and a method of drilling rock. The drilling machine comprises a reciprocating piston (19), which has sleeve-like configuration. Inside a central opening (20) of the piston is arranged one or more fluid passages for conveying pressurized fluid during work cycle of an impact device of the drill machine.
(FR) L'invention concerne une machine de forage de roche de fond de trou et un procédé de forage de roche. La machine de forage comprend un piston à va-et-vient (19), qui a une configuration de type manchon. A l'intérieur d'une ouverture centrale (20) du piston sont réalisés un ou plusieurs passages de fluide pour acheminer du fluide sous pression pendant un cycle de travail d'un dispositif d'impact de la machine de forage.
