2. The device according to claim 1, that is, that the drive shaft is made POH1YM with radial holes on the side surface - and is connected to the pneumatic system of the weaving machine. 3. Device in accordance with Clause 1, regarding the fact that the valve is connected to the drive shaft By means of at least one lead positioned opposite the valve slot. 4. The device according to claim 3, that is, so that the flap of St. 92631 . Zana with leads movably in the radial direction. 5. A device according to Claim 1, characterized in that the pressure cylinder additionally has openings for connecting nozzles that are offset relative to the main openings and associated with them by means of bypass channels. 6. The device according to claims 1 and 5, characterized by the fact that the bypass channels are formed by an arcuate groove in the end face of the pressure cylinder and the holes connected with the groove parallel to the axis of the cylinder. one The invention relates to textile manufacturing and is intended to control the air supply to the relay nozzles of a pneumatic weaving machine. The purpose of the invention is to enhance the performance of work. Figure 1 shows the proposed device, a longitudinal section; figure 2 - section aa in figure 1; on fig.Z - section BB in figure 1; figure 4 is an internal view in the scan of figure 1; on fig.Z - work diagram for one revolution of the main shaft of the machine. On the stand 1 of the weaving machine (not shown), the control device 2 is fixed, having a pressure cylinder 3 with end caps 4 and 5. The pressure cylinder 3 has through holes 6 (female) on the side surface for connection through air ducts 7 of several nozzles (not shown) loom installed along the path of laying the weft yarn. Inside the cylinder 3, a distribution cylindrical valve 9 is installed on the drive shaft 8, having an elongated hole 10 for passing air successively into each of the holes 6 of the pressure cylinder 3. The valve 9 is made as a segment and the hole 10 therein is in the form of a slot between the side edges 11 segment parallel to its axis. Holes 6 are located along a helix, and the valve 9 is in contact with the inner surface 12 of the cylinder 3. The drive shaft 8 is made hollow, has radial holes 13 for the passage of air and is connected by an air duct 14 to the pneumatic system of the machine. . The valve 9 is connected to the shaft 8 by means of pins 15, which are located opposite the opening 10 movably in the radial direction. The holes of the female are offset from the holes & and connected with them through bypass channels 16, 16a-16e, made in the form of holes in the cylinder 3 and channel 17, formed by an arc groove located at the end of the cover 5 at an angle of about 160. The cover 5 is rotatably mounted around the axis of the cylinder 3, which allows the bypass channel 17 to be positioned above the required number of holes 16, 16a-1be. The single shaft 8 has at the end a toothed pulley 18 with a driving belt 19, by means of which the valve 9 is rotated in the direction of the arrow 20. Air is supplied to the device through the air duct 14 in the direction of the arrow 21. Under the influence of the internal air pressure, the valve 9 is resiliently pressed against the inner surface 12 of the cylinder 3. It can be made of synthetic material in order to avoid the use of lubricant, thereby preventing the ingress of lubricant into the air, nozzles, weft thread and fabric. The diagram (Fig. 5) along the working width of the loom, in the direction indicated by the arrow B, shows the installation of six control devices 2, indicated respectively 22-27. On. the diagram also shows: 28, 28a-29d start, air supply to the air ducts 7; 29, 29a-29d - end of filing; 30 - the duration of this filing. The number of control devices 2 installed in the working width of the tank may be more than six. Each individual control device may have more than five connecting ducts 7 for the associated nozzles. It is also possible to connect to each connecting pipe, for example, three nozzles so that they receive air simultaneously. Finally, a control device (as shown in Figures 1-4) can be used to control a so-called main feed nozzle located on the side of the weft thread of the weaving machine outside the throat. The hole 10 of the valve 9 should not be parallel to the shaft 8, it; may have, for example, a helical view, may pass in the direction of the helical shape of the arrangement of the openings 6, however with a different inclination or in the opposite helical direction. Its width may be different. The device works as follows. The distribution valve 9 receives rotation from the main shaft of the machine through the drive belt 19, the pulley 18, the drive shaft 8 and the pins 15. Air into the cavity of the cylinder 3 is supplied from the pneumatic system of the machine through the air duct 14 and the holes 13 of the drive shaft 8. Oblong hole (slits) 10 damper 9 passes successively above the holes 6 which are screw-shaped on the cylinder 3, respectively, and air is supplied to the machine nozzles. In the position shown in FIG. 3, the bypass channel 17 is opposite channels 16, 16a-16c and connects them to each other. In accordance with this arrangement, the air ducts 7 receive air from the start of the supply (28, 28a-28d) to the end of the supply point (29, 29a-29d) for a time 30 corresponding to the angle of rotation of the main shaft of the machine, the same for all these four nozzles . The connecting duct 7, right in Figures 1 and 2, and the nozzle connected to it, receive air from the moment of their opening (28d) until the moment of closing (29d) at the end of the introduction duration equal to the angle of rotation C of the main shaft, applied to the ordinate. . For control devices 22-27, air passes to the corresponding nozzles, however, time 30 for them is somewhat biased compared with the previous control device. Each control device through the nozzle air supply, corresponding to the last shown on the right of the duration, is made up to the end of the duck gasket. This is achieved by the corresponding message of the openings 6 of the right (of FIG. 1) connecting duct 7 and the associated axial channels 16, 16a-16c with the bypass channel 17. By turning the knob 5 and changing the position of the bypass channel 17, you can change the duration of blowing through the last nozzle separate control devices 22-27. If, after prolonged use, abrasion occurs on the working surfaces of parts 3 and 9, then due to the pressure in the cavity of the cylinder 3, as well as centrifugal force, the distributor valve 9 expands somewhat more, thereby constantly moving its working surface with a seal on the surface 12 cylinder 3. The application of the invention will improve the reliability of the device by creating close contact between the working surfaces of the cylinder and the valve, regardless of the consequences of their wear.
