Abstract

Le perforateur hydraulique roto-percutant (2) comprend un corps (3) ; un emmanchement (15) ; un piston de frappe (5) configuré pour frapper l'emmanchement (15) ; un piston de butée (13) comportant une face avant (18) tournée vers l'emmanchement (15) et une face arrière (19) située en regard d'une paroi arrière (21) d'une cavité (14) recevant le piston de butée ; et un circuit principal d'alimentation hydraulique comportant un conduit d'alimentation en fluide à haute pression (9) et un conduit de retour de fluide à basse pression (11). Le corps (3) et le piston de butée (13) délimitent une première chambre de commande (22) reliée de façon permanente au conduit d'alimentation en fluide à haute pression (9) et configurée pour solliciter le piston de butée (13) vers l'avant, et une deuxième chambre de commande (25) configurée pour solliciter le piston de butée (13) vers l'avant et reliée en permanence à un accumulateur basse pression (26) relié au conduit de retour de fluide à basse pression (11).
