摘要
Injection nozzle for high-pressure injection drilling systems comprises a nozzle body and a fluid channel (8) for the injection fluid having a non-round internal cross-section and extending through the nozzle body in a longitudinal direction. An Independent claim is also included for a high-pressure injection drilling tool comprising the above injection nozzle. Preferred Features: Rib-shaped guide profiles (9) protrude into the fluid channel. The guide profiles extend in the longitudinal direction of the nozzle, preferably over the entire length of the nozzle. The injection nozzle has a star-shaped internal cross-section.
