    The cage for the valve seat is provided with cooling ducts which are uniformly spaced about the cage. Alternating ducts are used as coolant supply ducts while the remaining ducts are used as exhaust ducts. The ducts are arranged to uniformly cool the cage and valve seat. Suitable cross ducts are used to achieve a uniform distribution of the coolants supplied to the cage as well as a uniform removal of a coolant.

    (54) EXHAUST VALVE BODY
    The invention relates to the field of engine management. An exhaust valve housing for an internal combustion engine is known, comprising a guide part with inlet and outlet cooling cavities separated by a septum, a seat part with an annular cooling chamber communicated to the channels with inlet and outlet cavities, the channels being distributed around the circumference of the housing evenly l. However, the temperature is unevenly distributed in the valve seat area. This impairs the heat transfer from the valve to the seat. The purpose of the invention is to increase the cooling efficiency. This is achieved by the fact that the inlet and outlet cavities are located one on another in the axial direction, and the channels communicating with the inlet and outlet cavities alternate between each other. FIG. Figure 1 shows schematically an exhaust valve body with cooling cavities arranged one above the other, partly cut away; in fig. 2 shows section A-A in FIG. in fig. 3 shows a section BB in FIG. in fig. A 4-cprpus with two teams cavities located at the same distance from the saddle, option; in fig. 5 - the same, another option; in fig. 6 is a sectional view BB in FIG. four; in fig. 7 - section GGD in figure 4. The body of the exhaust valve 1 contains a guide part 2 with a supply 3 and a discharge 4 cooling cavities, which are separated from one another by a partition 5. Each of the cooling cavities 3, 4 with three channels communicates with the annular cooling chamber 7 located in the saddle section but channels may be more. The channels 8-13 are evenly spaced around the circumference of the housing 1 and alternately alternate. Channels 9, 10, 11 communicate the supply cavity 4 with the chamber 8, and channels 12, 13, 14 communicate the outlet cavity 5 with the chamber 8. The cavity 4 is connected to the source of cooling means (not shown) by means of a connecting nipple 15. To divert the KZ short-circuiting cooling agent by channel 16, it is connected
    a connecting nipple 17, which is connected to the outlet of the coolant.
    In the area of the channel 18 for exhaust gas exiting the combustion chamber, the channels 13, 12, 14 and 9, 11, 10 are made in the form of drillings, in the racks 1 In the zone I of the cavity 5, the channels 13, 12, 14 are located in projecting parts 20 of the wall 1.Cavities 4.5 (Fig.47) are located approximately at the same distance from the saddle part and each covers part of the circle 1. Channels 9 and 10 directly extend from cavity 4 and are drilled, and channel 11 through radial drilling 21 in crossmember 22 is connected to a slot cavity 23. This cavity 23 by drilling 24 is connected to cavity 4 The outlet cavity 5 is directly connected through channels 13 and 12 to the annular chamber 8. In addition, the cavity 5 through radial drilling, 25, the slot cavity 26 and the drilling 27 in cross member 28 is connected to channel 14, which is located in the housing part 1 opposite cavity 5. Holes in the shell eKkrygy caps 29, 30.
    When operating through the nipple 1, cooling means is supplied to the inlet cavity 4, which means about channels 9, 11, 10 enters chamber 8. From the chamber, coolant flows through channels 13, 12, 14 alternating with channels 9, 11, 10, enters the discharge cavity 5, from where it can be removed through the channel 16 and through the nipple 17.
    Due to the alternation of the supplying 9, 10, 11 and exhausting 12, 13, 14 channels, the temperature in the seat part is favorably distributed, with a corresponding increase in heat transfer from the valve body to the seat part.
