PURPOSE:To increase the lubricant flow utilizing the oil cooler drain, by providing a conduction oil path for utilizing the drain of relief valve provided in the oil cooler oil path for lubrication. CONSTITUTION:A conduction oil path 65 will conduct between the drain port of a cooler bypath valve 62 and a lubrication oil path 6E through a check valve 64 where the excessive oil in the cooler circuit 6C discharged from the drain port is fed through the check valve 64 to the lubrication oil path 6E to be used for lubrication. A bypath relief valve 63 is placed between the cooler bypath valve 62 in the conduction oil path 65 and the check valve 64 and upon increase of the lubrication pressure when the lubrication oil temperature is low, the conduction oil path 65 pressure and the cooler circuit 6c will increase as the increase of the lubricant pressure to prevent the oil cooler from damage due to increase of cooler pressure, thus to leak the excessive oil upon increase of the conduction oil path 65 above setting. |
