Abstract

　エンジンＥにより駆動される第１の油圧ポンプ１および第２の油圧ポンプ２と、第１の油圧ポンプ１からの圧油を圧力調整弁２１により調圧してトランスミッション制御装置３にクラッチ制御圧として導くとともに、圧力調整弁２１を通過した圧油をトルクコンバータ４にトルコン作動油として導き、さらにトルコン通過後の圧油をオイルクーラ２３に導く第１の油圧回路Ｌ１と、圧力調整弁２１とトルコン４の間の第１の油圧回路Ｌ１に接続され、トルコン４の入口側の圧力が所定値Ｐ２２以上になると、そのトルコン入口側の圧油をタンクへ逃がす安全弁２２と、第２の油圧ポンプ２からの圧油を圧力調整弁２１の下流側かつ安全弁２２の上流側と、トルコン４の下流側かつオイルクーラ２３の上流側とに分配する第２の油圧回路Ｌ２と、トルコン４の入口圧の増加に伴いトルコン４の下流側かつオイルクーラ２３の上流側への流量割合が増加するように、第２の油圧回路Ｌ１の流量配分を変更する流れ制御部２４とを備える。
