The upper part of the filter seat is provided with a vertical plate 3 for fixing the oil cooler. The vertical plate 3 is arranged vertically. Two oil coolers 2 are arranged side by side on the back of the vertical plate 3. The front of the vertical plate 3 is provided with a filter and oil outlet The cooling oil inlet passage 7 connected with the oil passage 5 and the cooling oil return passage 8 connected with the oil outlet of the oil cooler 2, the cooling oil inlet passage 7 is connected with the oil inlet of the oil cooler 2, and the cooling oil return The oil passage 8 is provided with two oil outlets 9, one oil outlet is connected with the main oil passage of the body for lubricating bearings and other components, and the other oil outlet is connected with the auxiliary oil passage of the body for cooling the piston Nozzle oil supply, cooling oil inlet oil passage 7 and cooling oil return oil passage 8 are vertically oppositely arranged on both sides of the vertical plate 3 . A bypass oil passage 12 is connected between the cooling oil inlet passage 7 and the cooling oil return passage 8, and a bypass valve is provided on the bypass oil passage 12. When the oil temperature is low and the oil cooler 2 is blocked, the oil can Smoothly bypass the oil cooler 2 to reach the parts to be lubricated.

The cooling oil return oil passage 8 is connected with a pressure relief oil passage 11, and the pressure relief oil passage 11 is provided with a pressure limiting valve. The pressure limiting valve can limit the maximum pressure of the oil in the main oil passage inside the body. Once the oil pressure in the main oil passage in the body exceeds the set value of the pressure limiting valve, since the pressure in the pressure relief oil passage 11 is the same as the oil pressure in the main oil passage of the body, this pressure will The pressure limiting valve is quickly opened, excess oil is discharged through the pressure relief oil port 10, and the pressure in the main oil passage of the body is instantly reduced to the opening pressure value of the pressure limiting valve, so that the engine oil pressure is within a normal range.

The filter oil inlet passage 4 is provided with an oil inlet, and the oil inlet is connected with a centrifugal filter 16 through a pipeline. Centrifugal filter 16 gets machine oil from filter oil inlet passage 4, circulates and filters the machine oil in the engine oil sump, reduces the impurity in the machine oil, prolongs the oil changing period. The filter oil inlet passage 4 is also provided with a pre-supply oil inlet, and the pre-supply oil inlet communicates with the oil outlet of the oil pre-supply pump 13 through the oil pre-supply pump oil outlet pipe 15, and the oil pre-supply pump 13 is fixed On the vertical plate 3, the engine oil pre-supply pump oil inlet pipe 14 stretches into the oil pan of the engine.
