    This invention relates to the mining industry and increases the reliability of the executive bodies of mining machines. The actuator includes a tool holder (P) 1 with a cutter 4, a valve and a nozzle 13. P 1 is made with a fitting (PO) 2 for placement with the possibility of limited axial movement and, if necessary, rotation of the shank 3 of the cutter 4. Cutter 4 is made with a shoulder 6, interacting in the extreme lower position of the cutter 4 with an emphasis of 5 P 1., On 1

    The PO 2 surface is made through the holes 16. They are located between the valve seat 11 and the end 17 of the shank 3 of the cutter 4. Formed by the openings 16, the canals are located at an acute angle to the PO 2 axis. The apex of the angle is directed to the mouth of the software 2. The erase 12 of the valve head 10 is installed in the opening 19 of the valve body 9 with sealing by means of a sealing ring 20 provided with a slot.
     During the work of the executive body
    the shank 3 of the cutter 4 acts on the stem 12 of the valve head 10 and lifts it from the seat 11, the lifting height of the valve head 10 is greater than the axial path of the cutter 4 until it stops 5. Water is supplied through the annular groove to the nozzle 13. Water is sprayed onto the cutter 4 or chest slap Through the holes 16 and the channels, the dirt is collected, which is collected from the shank 3 of the cutter 4. 5 3, p. 3 il.

    Isobrade refers to the gorma, PROPOSITION: namely, to the executive bodies of the mountain, mother's.
    The purpose of the invention is to increase the reliability of the executive bodies of mining machines.
    FIG. 1 shows the executive body, a longitudinal section; FIG. 2 is a view A in FIG. one; in fig.Z - section bb in fig,
    The field body of the mining machine includes a tool holder 1, in which a blind mounting hole 2 is made for a longitudinal movement set by B with a capacity of longitudinal movement and vrzez-) and around its axis of the shank 3 of a tool 4, the tool holder 1 includes a stop 5 with which the ledge 6 of the cutter 4d can interact, thereby restricting the movement of the needles of the tovik 3 in the direction of the cutting forces. The toolholder 1 in sections 7 is welded to a cut-in crown (not shown);
    In the rear part 8 of the landing bore .2 there is a clan housing 9 with an IC head, a saddle 11 and a shaft 12, the lOianaHj is designed to regulate the supply of water to the injector 135 and is located coaxially to the landing bore 14 of the TeBepcTiBo 2 s made in the lower part of the shank 3 cutter 4, the Core 12 holoeki 10 klgshan installed in the valve housing 9 with a gap and communicates with the end face 15 of the shank 3 cutter 4,
    On the side surface of the mounting bore 2, there are 1 SKBO bores 16, p5ac. Fitted;; to, with a seat of 1 valve and an end face 17 XB.

    4, located in the lowest position. The channels 18 formed by the through holes 16 are located to the axis of the mounting hole 2 at an acute angle, the apex of which is directed towards the mouth of the mounting hole.
    Valve stem 12 is installed. in the hole 19 of the valve body 9 with sealing by means of a sealing ring 20 provided with a notch.
    B bore hole 2 can be pressed sleeve (not shown). Annular grooves 21, 22 and 23 are provided on the inside of the bore 2, a seal can be inserted into the annular groove 22. The annular grooves 2 1 and 23 can be used as earthquake grooves. If a bushing is pressed into the bore 2, the grooves 21 22 23 23 can be provided on the inside of this bushing.
    The device works as follows.
    During cutting, the shank 3 of the cutter 4 moves in the direction of the cutting force, lifts the valve head 10 from the seat 11 and releases water supply along the annular groove to the nozzle 13 placed in the tool holder 1, through which a water jet is sprayed onto the cutter 4 or on the bottom of the chest, however, it is possible to raise the height of the valve head 10 more than the axial path of the tool to the stop. The flow of water into the space in front of the valve seat 11 is characterized by a water inlet channel through the opening
    in the tool holder 1 (not shown). Penetrating into the bore hole 2 is discharged to the outside through the through holes 16 and channels 18. Since the clamping ring 20 is made with a slit, a certain amount of seeping water can pass into the space behind the shank 3 of the cutter 4, This seeping water, the amount of which is determined through the sealing ring 20, it is washed away through the openings 16 and the channels 18 gathering dirt in the space behind the shank 3. This is favored by the fact that in the area of the end face 17 of the shank 3 there is a longitudinal groove in which there is a valve stem 12. Thus, an annular gap is formed, which is washed with seeping water.
