    The invention relates to coal cutting equipment and improves the cooling efficiency of the cutters. For this B, the executive body of the protrusion B of the support (O) 3 FOR the cutting cap (RK) 6 is cylindrical. The protrusion 3 is made with an annular groove 7. PK 6 has an annular groove 8 and is mounted on the protrusion 3, the annular CAVITY formed by the annular grooves 7 and 8 is intended for the fixing element. A spring-loaded connecting link (NW) 10 and a valve 11 are installed in the hole 903. The latter is tubular and integrally formed with NW 10. The NW 10 is installed in the clearance slot of the protrusion 03c and has a sealing ring 32. With the valve 11 pushed back, the cooling water enters the cavity 23, through the channels 24 and the annular groove 25 in with the channel 26 into O 3. From the channel 26 cooling water flows through the annular groove 27 and channels 28 and 29 to the nozzle 30. 2 C. f-ly, 1 IL.

    The invention relates to the mining industry, and in particular to the executive bodies of mining machines.
    The purpose of the invention is to increase the cooling efficiency of the cutters. 5
    The drawing shows the Executive body, axial section.
    The tool holder 1 with its surface 2 is flanked to the executive body. In the tool holder 1 inserted 10 support 3 of the tool (screwed with thread 4). Seal provided
    5. On the support 3, a cutting cap 6. is mounted rotatably. An annular groove 7 in the “pore and an annular groove 8” in the cap body 6 forms an annular cavity in which the retaining ring is located. The groove 7 in the axial direction is larger than the snap ring located in it 20, so the cutting cap 6 mounted on the support has the possibility of axial movement.
    In the central channel 9 of the support 3 25, an axial link 10 is mounted that can be moved axially, which is integral with the valve cone 11. With a spring 12, the valve cone II is pressed against the valve seat 13. This spring is simultaneously through the connecting link 10 acts on the cutting cap 6 in the direction opposite to the cutting force, therefore, in the 35 initial position, the cap 6 is raised above the shoulder 14 of the support 3 by a value of I. As soon as the cutting force occurs, the valve 11, overcoming the resistance of the spring. 1 2, moves away from the 40 saddle, and the cap sits on the shoulder
    14.
    A channel 15 for supplying cooling water is located in the tool holder. 45 Through the ring groove 16 in the support 3, cooling water flows through the channels 17 into the annular cavity 18 and from there through the channels 19 of the valve body 20 into the cavity 21. The housing 20 in the area of channels 50 surrounds the ring filter 22. With the valve And the cooling valve retracted water enters the cavity 23 and from there through the channels 24 and the annular groove 25 into the channel 26 in the 55 support 3, from which the cooling water flows through the annular groove 27 and the channels 28 and 29 to the nozzle 30.,
    In the groove 31 of the connecting link 10, an o-ring 32 is inserted, for example of hard plastic, having a slot, so a small amount of water passes through it from the cavity 23. The connecting link 10 is located in the channel 9 of the support 3 with a gap, therefore, a small amount through the gap in the seal 32 water enters the cavity 33 between the support 3 and the cutting cap 6. This water flows through the annular gap 34 between the support 3 and the cap 6 into the space 35, as a result of which the annular gap 34 is washed.
    The valve body 20 is screwed into the support 3 using a thread 36.
