Cooling water is pumped through the cooling water pipe 5 by a cooling water pump (not shown) and introduced into the cooling chamber 4. The cooling water flows through the cooling chamber 4 as shown by the arrow in FIG. 1, cools the cylinder liner 2, and then connects. It flows into the cylinder head 3 through the hole 6. In such an internal combustion engine, foreign matter mixed in the cooling water settles and accumulates in the lower part of the cooling chamber 4, and also adheres to the outer circumferential surface of the cylinder liner 2, resulting in insufficient cooling of the cylinder liner 2 and, as a result, piston damage. There were problems such as seizure and piston ring sticking.

従来のものに較べ、冷却室４内に運ばれる異物の量は著
しく少なくなる。An intake port of a cock 9 screwed onto the flange 5a of the cooling water pipe 5 is opened at the lower part of the liquid storage chamber 7. In the above device, a cooling water pipe 5 is operated by a cooling water pump (not shown).
The cooling water pumped through the interior temporarily accumulates in the liquid storage chamber 7 and then passes through the constriction passage 10 formed between the tip of the deflection plate 8 and the outer plate of the cylinder block 1 to the cooling chamber. 4. The cooling water in the cooling chamber 4 flows along the outer periphery of the cylinder liner 2 as indicated by the arrow in FIG. 2, cools the cylinder liner 2, and then flows into the cylinder head 3 through the communication hole 6. Foreign matter mixed into the cooling water is stored and precipitated in the liquid chamber 7, and accumulated at the bottom of the liquid storage chamber 7. Further, the foreign matter is separated from the cooling water and precipitated when the cooling water collides with the lower surface of the deflection plate 8 and when it is deflected by passing through the throttle passage 10. Therefore,
Compared to the conventional system, the amount of foreign matter carried into the cooling chamber 4 is significantly reduced.
貯液室７底部に貯つた異物はドレンコック９を開放する
ことにより外部に排出される。第４図は本発明の他の実
施例を示し、この場合は、貯液室７０をシリンダブロッ
ク１とは別体の箱体７１内に形成している。Foreign matter accumulated at the bottom of the liquid storage chamber 7 is discharged to the outside by opening the drain cock 9. FIG. 4 shows another embodiment of the present invention, in which the liquid storage chamber 70 is formed in a box 71 separate from the cylinder block 1.
７２は箱体７１に内設された偏向板、７３は貯液室７０
の上部と冷却室４とを接続する冷却水管てある。72 is a deflection plate installed inside the box body 71, and 73 is a liquid storage chamber 70.
There is a cooling water pipe connecting the upper part of the cooling chamber 4 and the cooling chamber 4.
冷却水管５を通つて貯液室７０内に流入した冷却水は、
ここで一たん溜つた後、偏向板７２により偏向せしめら
れ冷却水管７３を通つて冷却室４内に導入される。The cooling water that has flowed into the liquid storage chamber 70 through the cooling water pipe 5 is
After it has accumulated here, it is deflected by the deflection plate 72 and introduced into the cooling chamber 4 through the cooling water pipe 73.
冷却水中の異物は、冷却水が貯液室７０内に溜つた際並

面への附着が阻止される。Foreign matter in the cooling water is removed from the liquid storage chamber 72 when the cooling water accumulates in the liquid storage chamber 70 and when the cooling water is deflected by the deflection plate 72.
It is deposited at the bottom of the tank. The present invention is constructed as described above, and according to the present invention, foreign matter in the cooling water is precipitated in the liquid storage chamber, so the amount of foreign matter carried into the cooling chamber is significantly reduced compared to the conventional method. Therefore, such foreign matter is prevented from accumulating in the cooling chamber and adhering to the outer circumferential surface of the cylinder liner.
