PURPOSE:To supply a proper amount of lubricating oil to each part to be lubricated, by grouping the lubrication parts in compliance with changes in the requisite oil quantity caused by the temp. of a transmission, diverging the lubricating oil path in accordance therewith, and furnishing a flow control means of thermal response type in part of the branch path. CONSTITUTION:The pressure oil from a pump 7 is normally supplied to a first position hydraulic clutch C1 while a manual valve 9 is in auto-shift position, and is supplied or exhausted by a shift valve unit 10 to/from the second position thru the fifth position hydraulic clutch C2-C5. Meantime the working oil is supplied from a regulator valve 11 to a hydraulic control circuit 12 of a clutch for torque converter through an oil path 12a. The oil exhausted from a port 11a of the regulator valve 11 is supplied to lubrication parts of a transmission through a lubricating oil path 13, which is diverged into a plurality of branch paths 131, 132. A relief valve 14 is furnished upstream of the divergence point, and one of the branch paths 132 is fitted with a choke type throttle 15 as a flow control means of thermal response type. |
