Simultaneously with starting the automobile engine 10, the lubricating oil pump 11 is driven to rotate, and as a result, the lubricating oil stored in the oil pan 10b is discharged into the discharge oil passage 12. When the engine 10 is started, the engine 10 is in a low temperature state, so the alloy spring 23 is in an extended state and the discharge port 24 is in a completely closed state. Therefore, the entire amount of lubricating oil discharged from the lubricating oil pump 11 is distributed between the valve hole 20 corresponding to the small diameter portion of the valve body 21 and the first
It is discharged through the supply passage 30 to a lubricated location within the cylinder block 10a.

Ｌ２の寸法を適宜設定すればよい。 When the temperature of the automobile engine 10 rises after a certain period of time and exceeds a certain temperature and enters a heated state,
The alloy spring 23 is compressed and the valve body 21 is moved to the position shown in Fig. 2b.
The valve body 2 is moved to the position shown in FIG.
The area where the second supply passage 31 opens to the valve hole 20 corresponding to the small diameter portion of the valve body 21 decreases, and the area where the second supply passage 31 opens to the valve hole 20 corresponding to the small diameter portion of the valve body 21 increases. As a result, the lubricating oil flowing into the first supply passage 30 decreases, and the lubricating oil flows into the second supply passage 31 by the amount of decrease.
The lubricating oil that has flowed to the second supply passage 31 flows to the return passage 32 via the hydraulic motor 16, and the lubricating oil flows to the return passage 32 via the hydraulic motor 16.
The cooling fan 18 is rotated and the cooling fan 1 is rotated.
8, outside air is introduced and the automobile engine 10 is actively cooled. The oil that has flowed to the return passage 32 further flows to the first supply passage 30, merges with the lubricating oil from the discharge oil passage 12, and lubricates each part of the automobile engine 10. In this way, since the lubricating oil from the discharge oil passage 12 and the return flow from the hydraulic motor 16 are combined in each part of the automobile engine 10, the amount of lubricating oil supplied to the hydraulic motor 16 is controlled. Regardless, it doesn't change. Therefore,
Each part of the automobile engine 10 can be lubricated with one pump, and the hydraulic motor 16 can be driven, so that the power consumption of the engine driving the pump can be reduced. The supply flow rate of lubricating oil supplied to the hydraulic motor 16 is determined by the width L1 of the large diameter portion and the distance L2 between the large diameter portions. Hydraulic motor 1
To change the amount of lubricant supplied to L1,
The dimension of L2 may be set appropriately.

The two supply passages are branched and connected, and by the action of a shape memory alloy that is sensitive to engine temperature at this branch connection part, a valve body is installed to cut off communication between the discharge passage and the second supply passage when the engine is at low temperature. Then, it moves to two positions: a position where the discharge passage and the first supply passage communicate with each other, and a position where the communication between the discharge passage and the first supply passage is throttled and the discharge passage and the second supply passage communicate with each other when the engine is at high temperature. The structure is such that a return passage for guiding the return lubricating oil from the hydraulic motor to the first supply passage is connected to the hydraulic motor and the first supply passage. Since all the lubricating oil discharged from the pump flows to each part of the engine, a single pump can drive the hydraulic motor and lubricate each part of the engine, resulting in the effect of reducing the power consumption of the engine that drives the pump. .
