ABSTRACT A direct drive for deep-well drill bits on the Moineau displacement principle is provided with locking means detents (10, 11) which are disposed downstream of the working chambers (4) of rotor (3) and stator (2). Actuation of the locking means is effected by coupling throw-in members (13) introduced through the flushing passage from above. Passage through the working chambers and into the locking means detents groove (16, 20, 21) is rendered possible for the throw-in members on relative rotation of rotor and stator.
