Claim 12:
13. The directional drilling system according to claim 12, wherein the control unit is configured such that the signals thereof received by the particle deflection device cause the time periods in which the actuators of the particle deflection device deflect said first and second majority of the abrasive particles into the first and second channel to be synchronized with the rotational velocity of the drill bit, and to be timed such, that said one of said stream portions passes through the one or more abrasive jet nozzles while the abrasive jet nozzles are directed towards a selected angular sector of the borehole bottom, together with any of said drilling fluid passed into the first and second channel during the first and second time period, respectively, and said subsequent one of said stream portions passes through the one or more abrasive jet nozzles while the abrasive jet nozzles are not directed towards said selected angular sector of the borehole bottom.
