| titleOfInvention | Lowering drill with parallel flows for rotary motor and hammer respectively |
| abstract | SUMMARY The present invention relates to a submersible drilling machine driven by a drilling rig via a drill string, comprising a housing with a percussion hammer, the percussion hammer arranged with a drill bit mounted in a crown sleeve, a percussion piston with a piston surface arranged to strike a neck and a drill bit to steer the percussion piston forward and Ater, the valve alternately pressurizes and relieves a pressure chamber which, under pressure load, drives the percussion piston forward, the housing further comprising a water-powered rotary motor of the wing motor type comprising pressure chambers with wings which rotate the drill bit under pressure load. The liquid stream is led into the housing through a river distributor and is further distributed between the pressure chamber of the rotary engine and the pressure chamber of the percussion piston. |
