    An apparatus for venting and deaerating a liquid circuit, such as the coolant circuit of an internal combustion engine, has a surge tank with an air-side port and a liquid-side port. Installed in the air-side port is a tube, through one end of which liquid to be deaerated is admitted at a certain velocity. The tube has a longitudinally extending lateral slot through which the admitted liquid is discharged; opposite the slot is located a baffle onto which the discharged liquid impinges over a large surface area. This causes even small air bubbles to be liberated from the liquid so as to remain in the air-side part, whereas the deaerated liquid runs off the baffle and into the liquid-side part of the surge tank.

    (54) DEVICE FOR DEGASING AND DEAERATION OF LIQUID
    权利要求:
    Claims (3)
    [1]
    The invention relates to mechanical engineering, in particular, to devices for degassing and deaerating a liquid, such as a liquid from a cooling system of internal combustion engines. Devices for degassing and deaerating a liquid, such as a liquid from a cooling system of internal combustion engines, are known, which contain at least a pump and a surge tank equipped with fluid and air cavities, in the latter of which is an element for decompression of a liquid, for the removal of gas bubbles from it into air cavity and the flow of fluid into the fluid cavity. In such devices, due to the decompression of the fluid and the deceleration of its speed, the removal of gas bubbles is achieved, as a result of which the cavitation damage of the cooling systems of the internal combustion engines of Li is reduced. However, the known devices are not efficient enough and therefore the degree of removal of gas bubbles is low. The purpose of the invention is to increase the efficiency of degassing and deaeration. The goal is achieved by the fact that the element for decompression of a liquid is made in the form of a horizontal pipe, one of the ends of which is provided with a plug, and the other return pipe is partially located inside the pipe, equipped with an end cap and radial holes and connected to the cooling system, the pipe equipped with an outlet opening facing the side wall of the surge tank - the wall of the incident flow. At the same time, the outlet of the pipe is made along its entire length, and the wall of the incident flow is located at a certain distance from the outlet 39 and is at least partially covered with liquid. In addition, the pipe outside is provided with a guide element, which is located obliquely to the wall of the incident flow and with a gap relative to it. At the same time, the pipe is also provided with a drainage hole located 8 of the deepest part of the pipe, and the surge tank is equipped with a drainage channel at the entrance of which a guide plate is installed that prevents swirling. FIG. 1 is a diagram of pre, s; lagged device; in fig. Z - section Ana FIG. 1. The element for decompression of a liquid is made in the form of a horizontal pipe 1 and is installed in the air cavity 2 of the surge tank 3. The latter also has a fluid cavity 4. One of the ends of the pipe 1 is provided with a plug 5, and through the other a return pipe 6 is inserted, partially located inside the pipe and provided with an end plug 7. The return pipe 6 is equipped with several deflecting radial holes 8 located at the end face. plug 7 g and is connected to the engine cooling system (not shown). The outlet 9 of the pipe 1, made along its entire length, faces the side wall 10, the surge tank 3, and the wall 10 is located at a certain distance 11 from the outlet 9. In the lower part of the pipe 1 there is a drainage hole 12, as a result of which with a minimum amount of water in this pipe from the latter, water can always drain. In the lower part of the pipe 1, but outside it, there is a direction element 13, which is inclined to the wall 10 of the leveling tank 3 and forms a gap 1 with it. Equalizing tank 3 is equipped with a drainage channel 15. At its entrance a guide plate is installed 16, which prevents the turbulence of water. The device operates as follows. Water from the cooling system of the internal combustion engine enters the return pipe 6, and from it through the radial holes 8 into pipe 1. As a result, the fluid is converted by the fluid, the fluid from the pipeline 1 through the outlet 9 is directed to the free-stream wall 10, which is the side wall of the gravity tank 3, Direction to) and the 13th element is located in such a way that between it and the side wall of the surge tank remains a gap 1, allowing the fluid to flow down without foaming. Air gas and vapor bubbles located. in the liquid, when the latter exits from the outlet 9, the v separates into the air cavity 2 of the surge tank 3. The drain hole 12 is located in such a way that the liquid coming from it is also drained by means of the guide element 13. Installation in the surge tank 3 Plate 1b helps prevent fluid turbulence and eliminates the absorption of air. Thus, the invention makes it possible to increase the efficiency of the degassing and de-aeration of the idos and cooling systems of internal combustion engines. Claim 1, A device for degassing and deaerating a liquid, such as a liquid from an internal combustion engine cooling system, contains at least a pump and a surge tank equipped with a fluid and air cavity, in the latter of which an element is placed to decompress the liquid from gas bubbles into the air cavity and the flow of liquid into the liquid cavity., about tlhh | sohatsya the fact that, with a single increase in the efficiency of degassing and deaeration, the element for decompression of the liquid is made in the form of an isotonic pipe, one of the ends of which is provided with a cap, and the other with a return pipe partially located inside the pipe, equipped with an end cap and radial holes and connected to the cooling system, the pipe being provided with an outlet opening facing the side wall of the equalizer tank flow wall.
