The invention concerns a device for supplying hydraulic power to a rotary apparatus for percussive drilling (2) whereof the tool (3) is driven in one direction or another and subjected to the action of an impact device (6) acting independently of the rotation, of a hydraulic device (9) with forward movement enabling the tool to generate a pressure force on the ground, and optionally of a suction device (14) for the drilling dusts, driven by a hydraulic motor, the various hydraulic actuating elements being driven from a hydraulic liquid source under pressure through a hydraulic flow divider (16), a set of distributors (17, 18, 19, 20) and an assembly of branch pipes outside the apparatus, such as hose pipes. Said device comprises a branch pipe external to the apparatus (24) for communicating the return branch pipe (22) of the hydraulic device (4) driving the tool in rotation and the supply line (23) of the impact device (6), to add to the supply rate of the impact device the return flow rate of the rotation driving device.

Dispositif d'alimentation hydraulique d'un appareil de forage roto-percutant (2) dont l'outil (3) est, d'une part, entraîné en rotation (4) dans un sens ou dans l'autre et, d'autre part, soumis à l'action d'un dispositif de frappe (6) agissant indépendamment de la rotation, d'un dispositif hydraulique (9) d'avance permettant à l'outil de créer une force d'appui sur le terrain, et éventuellement d'un dispositif (14) d'aspiration des poussières de forage, entraîné par un moteur hydraulique, les différents organes d'actionnement hydrauliques étant entraînés à partir d'une source de liquide hydraulique sous pression à travers un diviseur de débit hydraulique (16), un ensemble de distributeurs (17, 18, 19, 20) et un ensemble de tubulures extérieures à l'appareil, telles que des flexibles. Ce dispositif comprend une tubulure extérieure à l'appareil (24), de mise en communication de la tubulure (22) de retour du dispositif hydraulique (4) d'entraînement en rotation de l'outil et de la ligne d'alimentation (23) du dispositif de frappe (6), pour ajouter au débit d'alimentation du dispositif de frappe, le débit de retour du dispositif d'entraînement en rotation.
