た。 Air governors are used in forklifts, so the environment in which they are used changes suddenly, such as going from a dry indoor environment to a humid outdoor environment. Therefore, they are exposed to environments that are prone to freezing, such as frost. Furthermore, since the governor throttle valve of the air governor cannot be manually operated unlike the carburetor throttle valve, even if ice forms, the operating conditions cannot be changed by manually operating the governor throttle valve. Therefore, there were problems such as the forklift running unstable and the cargo falling.

る。 The usual ways to prevent ice from forming on the air governor of an internal combustion engine equipped with an air governor are to guide the warm air around the exhaust manifold to the air governor through the suction cylinder of the carburetor, or to run a pipe inside the air cleaner. There is a method in which cooling water for an internal combustion engine is passed through the pipe to warm the air passing through the air cleaner and prevent the air from freezing.

での氷結防止効果は半減している。 However, the method of covering the entire exhaust manifold and guiding the warm air inside to the carburetor cannot cover the entire exhaust manifold in engines that have other parts around the exhaust manifold, so warm air can be efficiently routed to the carburetor. The air governor's anti-icing effect is not sufficient. In addition, the method of running a pipe inside the air cleaner warms a large amount of air that passes through the air cleaner, so the air is not warmed enough, and engine cooling water must be led to the air cleaner with a hose, which increases costs. . Furthermore, in both methods, since the vaporizer is located upstream of the air governor, the heated air is cooled by the vaporizer, and the anti-icing effect in the air governor section is halved.

こぼれるというメンテナンス上の問題があつた。 Although it is not an air governor, Utility Model Publication No. 53-42664 has been proposed as an anti-icing device for a carburetor. Since engine cooling water is circulated through the passage formed by the groove and the intake cylinder, there has been a maintenance problem in that the cooling water spills during replacement during repairs or the like.

次に図面に示す本考案の実施例について説明す

路の盲プラグである。 FIG. 1 is a schematic diagram of the installation positions of the heat transfer plates of the present invention, where 1 is the carburetor, 2 is the air governor, 3 is the intake manifold, 4 is the heat transfer plate, 5 is the gasket, 15 is the air governor body, and 16 is the air governor body. Governor throttle valve 17 indicates a governor throttle shaft. The heat transfer plate 4 is interposed between the vaporizer 1 and the air governor 2, and is connected to the air governor body 1.
It is in heat conductive contact with 5. As shown in FIGS. 2 and 3, the heat transfer plate 4 has an air passage 4a in the center.
is formed through the plate body 6, and an engine cooling water passage 9 is formed within the plate body 6, and an intake tube 7 and an extraction tube 8 are provided at both ends of the passage. The heat transfer plate 4
is made of a material with high heat conductivity. 10 is a blind plug of the passage.

できる。 As described above, when the engine cooling water passes through the cooling water passage 9 of the heat transfer plate 4, the heat transfer plate 4 is warmed, and the heat is conducted to the air governor 2, thereby heating the air governor 2. .
Therefore, by directly heating the air governor 2, it is possible to more reliably prevent frost from forming on the air governor 2, compared to a conventional anti-icing structure. Further, the air flowing in from the carburetor side is warmed when passing through the heat transfer plate 4 and the air governor 2, and this warmed air passes through the governor throttle valve 16 and the heat transfer plate 4 and the body 15 of the air governor 2. Since the heat is directly transferred to the governor throttle shaft 17 and the governor throttle valve 16, frost formation on the governor throttle valve 16 can be reliably prevented.

化による障害の恐れがない等の効果がある。 As described above, according to the present invention, it is possible to reliably prevent frost from adhering to the air governor, thereby preventing malfunctions of the air governor due to adhesion of frost, and the structure is simpler than before, reducing product prices. Of course, in this invention, the heat transfer plate 2 is provided separately and a passage for conducting the cooling water is formed therein, so the air governor 2 can be left as it is without any processing. Since the cooling water passage is formed in an independent heat transfer plate, straight holes are bored from the outer surfaces of both sides and intersect with each other, so that the cooling water passage is formed in a tunnel shape that communicates the inlet side with the outlet side. This heat transfer plate has the advantage that the holes can be easily machined by selecting the thickness and size of the plate, etc.
Its lower surface is in heat conductive contact with the air governor 2,
A gasket 5 whose upper surface is adiabatically thicker than the carburetor 1
Since the vaporizer and the air governor 2 are in contact with each other through the gasket, the formation of frost due to direct heating of the air governor is reliably prevented, and the thick gasket prevents the heat transfer plate from flowing into the vaporizer. Since heat conduction is blocked, there is no risk of failure due to high temperature of the vaporizer.

い。 Furthermore, since the passages are provided independently in the body by the heat transfer plate, there is no risk of the cooling water spilling during repair or replacement, which facilitates maintenance.
