    The invention relates to dvigaualestroeniyu.
    Known valve body for. internal combustion chamber with forced cooling, comprising a guide with inlet and outlet cavities separated by a partition, and openings for supplying and discharging coolant 7 located 10 in its upper part, a valve seat. with an annular cavity and two pairs , racks with internal longitudinal 'channels / connecting annular, saddle cavity with inlet and outlet cavities. nap * ^ 5 equal [1},. Channels of two racks, ras-. laid on one side perigord-. Ki, open at the bottom of one cavity. In a known construction, the coolant enters the annular cavity 20 from the inlet cavity of the inlet equal to the two adjacent struts along the internal longitudinal channels; coolant comes out of the cavity. . la through the two channels of the two remaining. .2 $ of adjacent racks. With this circulation ; coolant valve seat is cooled unevenly, which * leads to its deformation and violation. sealing between the ft valve seat. 3 ()
    The aim of the invention is to improve the cooling of the valve seat by increasing the uniformity of circulation of the coolant;
    This is achieved by the fact that the channels of the Pairs of diametrically opposite racks are in communication with one cavity (inlet or outlet). The valve body can be made in such a way that · one of the two channels of the pair of racks · communicates with the inlet (outlet) · cavity of the guide directly and in the zone farthest from the hole for supplying (draining) liquid / and the other. the channel of the pair of racks is communicated with the same cavity of the guide using a tube, and the free end of the latter is located in the Cavity. The free end of the tube located in the inlet cavity.
    . oriented toward the fluid inlet; the tube ’communicating the channel with the inlet cavity is S-shaped, and with the outlet / No-L-shaped. In the partition / separating the inlet and outlet cavities, a hole for the passage of tubes is made. In addition, the housing is made of two parts with a connector in the transverse cavity, the latter passing through the hole in the partition.
    In FIG. 1 shows a longitudinal section through a valve body; in FIG. 2 is a section AA in FIG. .1; in FIG. 3 - section: cut BB in FIG. 2; in FIG. 4 - g section CC in FIG. 1.
    The valve body 1 contains a guide 2 with inlet 3 and outlet 4 cavities separated by a partition 5 and holes 6 and 7 for supply. θ and coolant drain located in the upper part of the guide; a saddle 8c with an annular cavity 1 9 and two pairs of struts 10, 11, 12 and 13 with internal longitudinal channels 14, 15, 16, 17 connecting the cavity 15 with cavities 3 and 4. Channels 14 and 16 of diametrically opposite racks and 11 are in communication with the outlet cavity 4, and channels 15 and 17 of struts 12 and 13 with the inlet cavity 3. Channel 15 is connected to the inlet cavity 3 directly and in the zone farthest from the opening 6 for supplying coolant. Channel 16 is in communication with the outlet cavity 4 directly in the 25th zone farthest from the opening 7 for draining the liquid. Channels 17 and 14 are respectively communicated with cavities 3 and 4 by means of tubes 18 and 19. The free end 20 of the tube 18 located in the inlet cavity 3 is oriented towards the fluid inlet 6, and the free end 21 of the tube 19 · is located in the outlet cavities 14. The tube 18, which communicates the channel 17 with the inlet cavity 3. has an S-shape, and the tube'19, which communicates the channel 14 with the outlet cavity 4, has a G-shape. In the partition 5, times-. dividing the inlet 3 and the outlet 4 40 of the cavity, a hole 22 is made for the passage of the tubes 18 and 19. The valve body 1 is made of two parts and has a connector 23 in the transverse plane, which passes through the hole 22 in the partition 5.
    The cooling of the guide 2 and the valve seat 8 is as follows. ’
    The cooling liquid enters the cavity 3 through the opening jg 6. The pressure of the liquid is sufficient for its penetration simultaneously into the channel 15 and the tube 18, the cooling liquid enters the annular cavity of the seat 9 __ through the channels 15 and 17 diametrically opposite · 5 opposite stands 12 and 13 and flows in the direction of the arrows shown in FIG. 4, to the channels 14 and 16 of diametrically opposed posts 10 and 11, which serve to drain the coolant 60 from the annular cavity 9 of the seat 8 through the cavity 4 and the hole 7. Such a design will allow uniform distribution of the coolant in the annular cavity of the saddle, which eliminates deformation saddles and depressurization between the valve and a saddle.
