FIELD: wireless control of parameters in turbodrilling, particularly, simultaneous control of two parameters by a common device: geophysical parameter - direction of drilling, and technological parameter - rotation speed of turbodrill shaft. SUBSTANCE: device for control of angle of installation of deflecting tool additionally has curved sub and pipe-modulator connected with the end of turbodrill shaft through connecting unit and built inside of the central bushing of acoustic resonator. Sound absorbing throat is made in form of through longitudinal recess in eccentric weight. This longitudinal recess and one of the parallel longitudinal through sound-absorbing holes of the central hollow pipe of acoustic resonator are located in the same plane with the plane of curved sub in direction of its curving. EFFECT: higher efficiency. 3 dwg
