Water under pressure goes to space 26 in front of КК 7 and acts on it in locking centering simultaneously with spring force 12, deist vuishlm in the same direction. Then, under pressure, the water rushes into the space 17, the channels 18, the grooves 19 and the gap 20. Then the water flows through the holes in K 2 to the space 28 in front of the nozzle 8. From the nozzle 8, water is supplied to the cutter area to the bottom. 2 Il. The invention relates to the mining industry, namely to the executive organs of the cutting machines. The purpose of the invention is to increase the efficiency of the performance of the cutting machine of the cutting machines by providing the cutter with an oh-hull. Fig. 1 shows the executive body of the cutting machines, general view; in fig. 2 is a view A of FIG. one. The cutting body main actuator includes a cutter 1, which is installed in bearings in the housing 2 with the possibility of limited axial displacement a distance ... Position 3 indicates the surface of the housing 2 5 along which it is welded to the cutting head of the cutting machine. The cutter 1 is loaded against the cutting force acting in the direction of the arrow 4 through the pumping element 5, which is connected with the rod by the pusher 6 of the conical valve 7 for the overflow of the cooling water to the splintering of the pressurized water under pressure the rez 11 and i regions, wherein the pusher 6 is mounted from the housing 2 with the seal 9. The connecting element 5 through the adapter 10 communicates with the shank 11 of the cutter 1. The conical valve 7 is loaded by means of the spring 12, which acts in the direction of the locking 1 .I to lapana The pusher 6 of the valve 7 is provided with a piston 13 fixed on the side of the nozzle 8 rigidly connected to it, which is installed in the housing by means of a chassis 14 and a seal 15, while the piston 13 is connected to the conical valve 7 by means of a fitting thread 16. Between the conical valve 7 and piston 13 by an annular undercut created a space 17 into which the channels 18 flow to release water. Cylinder 14 is mounted in housing using outdoor O five 0 0 five 0 threads 19, while between the cylinder 14 and the housing 2 there is a gap 20. In the pusher 6, a through longitudinal bore 21 is made by means of which in the space 22 located above the piston 13, the pressure is maintained at the level of the atmospheric one. The key grooves 23 of the rod pusher 6 include apuiki 24, by means of which the pusher 6 is connected to the connecting element 1 - element 1 - element 5. In closed: - conical valve. 7 is adjacent to the seat of the valve 25. Between the pusher rod 6 of the E-J body 2, a space 26 is connected, connected with the holes 27. The device works as follows; And - image. The water under pressure is brought to 5 space 26 in front of the conical valve 7 through from; ze1: C GM 27 through not shown on the line; “the channels in the head and in the valve assembly 2 therefore act on the conical valve 7 in the blocking direction. In addition to the TorOj, the conical valve 7 is loaded with a gear with a prong of an injector 12, which acts in lock-in mode. The force acting through the connecting element 5 on the cutter 1 towards the cutting force acting in the direction of the arrow 4 is made up of the force obtained due to the pressure of the water and the force of the spring 12, With a conical valve 7, lifted from the valve seat 25, pressurized water flows from space 26 to space 17, from here through output channels 18 through not shown in the drawing grooves in external thread 19, by means of which cylinder 14 is fixed in housing 2, and through the gap 20 between the cylinder 14 and the drilled hole in the housing 2 flows to the space 28 in front of the nozzle 8 | From the nozzle Into the water, a sharp narrow stream 29 splashes into the chest of the nipple in the cutter I. The pressure of the water in space 28 is relatively high and may, for example, be t 200 bar. When the valve is closed, i.e. when the cone valve 7 is in contact with the valve seat 25, the water pressure in the space 26 acts on an annular surface whose value corresponds to the cross-section, i, of the outer edge 30 of the valve seat 25 minus the cross-section from the rod pusher 6. Once the force resulting from the pressure of water on the conical The body of the cutting machines, including a housing, in which, using bearings, is installed with a limited axial movement of the cutter, is driven by a connecting element with a pusher of a spring-loaded conical valve to shut off the supply of cooling water to the section. splashing water under pressure the valve 7, together with the force of the spring 12, will be overcome by the cutting force, 25 the nozzle, located in the area acting in the direction of the arrow 4, Ca, and the pusher is inserted into the valve. With the valve open in space 1-7, water pressure is set. which, with the exception of hydraulic losses, corresponds to a pressure in space 26. This water pressure with an open valve acts on the annular surface d, the value the housing is sealed, and the valve is installed with the possibility of opening when the tool is axially moved under the action of a cutting force directed opposite to the return force created by the pressure of water acting on the conical i-valve and by the spring, the rigidity of which provides the transverse cross-sec. P blocked water inlet to the piston e piston 13 minus the cross-section of the conical valve in spite of the cross section of the pusher 6. Since the weight of the latter and the internal cross-section of the pusher 6 are less their frictional resistances (Hsi tre- forces than the cross-sectional pis- nn), wherein n 13, this force acts in the HA 40 that, in order to increase the board effektivnos- closing valve. When the conical valve 7 is raised from the valve seat 25, then as a result, the return force that acts in the closing direction of the valve and 45 is installed in the housing with a seal against the cutting force (arrow 4), the space between the valve is made up of the force of the spring 12 and Because of the cooling of the cutter, the valve pusher is provided with a piston rigidly connected with it, a piston located on the side of the nozzle, a piston through at least one water outlet connected to the space in front of the nozzle, and a piston with a diameter greater than the diameter of the pusher, while the product of the pressure of water in front of the conical valve on the effective surface of the conical clutch loaded with pressure from the pressure of water acting on the annular surface d. The cross sections b, d, and d., Which are affected by the water pressure in the valve, are sized to be such that the return force is obtained mainly due to the water pressure. The return force of the counter-55 water. In the direction of closing, corresponds to the cutting force of the cutter 1, the return force acts. in the direction of the arrow 4. The spring 12 is selected in terms of its parameters such that it closes the cone valve 7 despite the effect of the weight of the conical valve and the tool, as well as the counteraction of the internal friction resistances and, accordingly, keeps it closed. For this, for example, it is sufficient if this spring is prestressed to a force of 120 N.
