A dry female farmer is in the engine 1, and the cooling water pump 33 is moved in the state filled with the engine cooling water. Through the first and second cooling water hose%, ", the hose connection member guides' from this hose connection member 3δ through the supply-side cooling water passage 41 in the crankcase cover M, and supplies μ ξ丨 丨 矬, 丄, 人 ,, ^ One should go to the oil cooling line 25. In this way, the engine cooling water flows through the oil cooling camp _ 7 | State & Road 25 < Wanshi, cooled by the engine cooling water Engine oil 30 in the oil pan 21 1. Engine cooling water flowing from the oil cooling pipe 25 passes through the cooling water passage 42 including the return side of the crankcase cover 24—the soft f connection member m of the cooling water hose 13. The cooling system supplies the water jacket 34 in the cylinder 4. Then, the engine cooling water for cooling the cylinder block η and the cylinder head 9 is passed from the cooling water outlet 34b of the cylinder head 9 through the fourth cooling water hose 39. Return to the uncle device 35 〇 ... Therefore, the i-hai cooling device 2 Cooling water through the cooling oil of the oil pan 21 within the conduit 25, flows into the water jacket of the engine〗 "the 'thus formed - the total amount of cooling water into the engine oil through the cooling conduit Μ. Therefore, the cooling efficiency of the oil can be improved compared with the previous cooling device. In addition, the oil cooling pipe 25 in the oil pan 21 is tied to the oil pan 85379 -12-200404952, and a large amount of oil 30 in the oil pan 21 is brought into contact as it extends toward the vehicle width and visibility. The dry surface of the agricultural foot is U-shaped, so it forms a way to increase the speed in the forward and backward direction. This is because the vehicle body flows in the forward and backward direction when driving. Because the oil in & pan 21 is wavy in the oil pan 21, the formation of the plane is like the resistance when the non-wave cooling water of the Xian Erji oil cooling pipe 25 is still formed; Engine swap. Willfully proceed with the heat of the engine oil 30. Furthermore, the cooling device 2 is like a car μ? The right side crankcase cover 24 forms a 10,000-thousand side wall of the oil pan 21, because the opening side end of the oil cooling pipe 25 in the engine 21 is supported on the crankshaft m, phase. ^ 24 'Also supports cooling water pump 33' Q This can be used to cool the cooling water pump 3 3 male and female μ, ... f and oil cooling pipe 25, and connect the second cooling water hose 3 7 answer彳 土 ^ 5 temple components, as an assembly supporting the crankcase cover 24. Therefore, the operation of assembling the components of the multiple cooling system described above to $ 1 can be performed early. In addition, since the cooling device 2 is provided with a supply-side cooling water passage 41 and a return-side cooling water passage 41 like a shunt passage 40 that communicates with the crankcase cover 24 on the left side of the vehicle body, relatively low-temperature engine cooling water flows through the aforementioned shunts. It flows from the upstream side of the oil cooling pipe 25 to the downstream side in a short-circuit manner. Therefore, the temperature of the engine cooling water entering the water jacket 34 of the engine i can be lowered than when the shunt passage 40 is not provided, so that the engine cooling water can be prevented from being excessively heated by the oil 30, and the proper temperature can be reduced. Engine cooling water is supplied to engine 1. -[Effect of the invention] As explained above, since the entire amount of engine cooling water passes through the oil pan -13-85379 200404952, the heat of the oil in the cooling water passage 'oil pan Θ efficiently transmits the cooling water. Therefore, the first The cooling device can sufficiently cool the engine oil. The invention claimed in the second scope of the patent application can be formed into a simple shape on the one side so that it is contained in the oil. However, the water uses the official road to reduce the resistance when the engine cooling water flows through it. Heat exchange while cooling the oil more efficiently. 1. Since the cooling water pipe has a simple shape, it can be formed inexpensively. Therefore, it is possible to provide a cooling device at a lower cost than the previous cooling water device. For the invention in the third scope of the patent application, since the cooling water f pump and U-shaped pipeline 'and the cooling water hose connected thereto can be regarded as an assembly supported on the crankcase cover, the aforementioned The assembly of multiple cooling system components into the engine is simple. The invention of the fourth item of the patent application, because the relatively low temperature engine cooling water passes through the shunt path from the upstream side of the side pipe to the downstream side with a short circuit, so it will enter the engine. The temperature of the cooling water of the engine of the man and the sheep < water jacket is lower than when the shunt passage is not provided. Therefore, the present invention can prevent the engine cooling water from being excessively heated up by the engine oil, and can supply the engine cooling water with an appropriate temperature to the engine.
