Abstract

Anordning for boring, omfattende en borestreng som har et rør (10) fra en spole ragende nedover i et borehull som bores, idet røret avspoles etter hvert som boringen skjer. En nedre ende av borestrengen holder en boremotor (28) som har et hus (26) og en borkrone (32) som drives i rotasjon i forhold til huset (26). Borkronen (32) og huset (26) er skrådd i en vinkel (38). En flerplatebrems (42) som aktiveres av et stempel (44) styrer innbyrdes dreining mellom motorhuset (26) og røret (10), for å regulere boreretningen.
