    in the form of an annular shape of the main body 5, in which the hollow body 6 is concentrically placed, connected via jumpers 7 and 8 to the main body. 5. Lintels 7 and 8 are hollow inside and made coaxially with holes 9 and 10 in the inner tube 3 Holes 9 and 10 are connected to a chamber 11 made as a ring in the outer tube 2 The main body 5 is open on both sides, with the end 12 on the flowing side, the valve is narrowed and is a valve seat. The hollow body 6 is also open on both sides. On the outer perimeter of the hollow body 6, namely at its end facing the narrowed side of the main body 5, the streamlined shape cover 13 is mounted for longitudinal movement, which upl impressed relative to the hollow body 6 by means of o-rings 14 and 15. At the other end of the cabinet, 6 has an additional streamlined cover 16, which is sealed relative to the hollow body 6 using o-rings 17 and 18. The caps 13 and 16 are a resistor body and are connected with the help of the rod 19. Where the rod 19 passes the zone of the lintel, the ends of the levers 20 and 21 are associated with it, which represent a mechanism of movement and are made in the form of fork arms 22 and 23. The fork arms 22 and 23 are installed on the main building lo 5, with rotation

    neither The ends 24 and 25 of the fork arms 22 and 23 are fastened to the pins 26, which are fixed to the ring 27 located around the inner tube 3 and rotatably on the rotation supports 28 fixed on the annular piston 29 The latter can only be moved in the axial direction. Under the annular piston 29, the working substance can be supplied through the channels 30 and 31 With the help of seals 32, 33 and 34, the annular piston and the channels are sealed relative to the outer pipe 2. When the annular piston 29 moves in any direction, the forked rocker arms 22 and 23 move rod 19 with covers 13 and 16 fixed on it in the opposite direction
    Instruments located in outer tube 2 (not shown) measure the spatial position of the guide rod and transmit information to an electro-hydraulic transducer located in the inner tube (not shown). The hydraulic pulses of the signals through the channels 30 and 31 actuate the annular piston 29, which moves the caps 13 and 16, changing the cross-section of the flow of washing fluid 35. As a result, pressure pulses are generated in the flow of washing fluid, which are recorded at the wellhead.
    For mounting the fork rocker arms and for maintenance, a cover 36 is provided in the annular chamber 11,
    In contrast to the structure of the device of Fig. 1, in the construction of Figs 2 and 3, the covers 13 and 16 are actuated by hydraulic or pneumatic means. Therefore, the need for an annular piston and forked rocker arms is eliminated. Instead, channels 37-40 are provided in the bridges, which are made coaxially with channels 41-44 in the inner tube 3. The working substance is fed into the channels 37-44 from a source (not shown) located in the outer tube 2, the channels enter two separated from each other other chambers 45 and 46 in the hollow housing 6, the working substance depending on the desired direction of movement
