OIL SUPPLY DEVICE

To provide an oil supply device capable of reducing loss of driving force for oil supply in a vehicle drive device.SOLUTION: An oil supply device 100 includes: a first oil-hydraulic pump 11 driven by driving force transmitted in a driving force transmission path; a second oil-hydraulic pump 12 driven by an electric motor 121; a first supply oil passage 31 supplying oil F to a lubrication object; a second supply oil passage 32 supplying oil pressure to engagement devices C0, C1; a first connection oil passage 41 connecting the first oil-hydraulic pump 11 and the first supply oil passage 31; a second connection oil passage 42 connecting the second oil-hydraulic pump 12 and the second supply oil passage 32; and a third oil passage 43 connecting the first connection oil passage 41 and the second connection oil passage 42, and provided with a first nonreturn valve 51 in the middle. A control valve 6 is provided at a downstream side of a first branch connection 41a. The control valve 6 makes oil pressure at an upstream side of the control valve 6 in the first connection oil passage 41 higher than oil pressure of the second connection oil passage 42, during the engagement operation of the engagement devices C0, C1.SELECTED DRAWING: Figure 2 【課題】車両用駆動装置における油供給のための駆動力の損失を小さく抑えることができる油供給装置を提供する。【解決手段】油供給装置１００は、動力伝達経路を伝わる駆動力により駆動される第１油圧ポンプ１１と、電動モータ１２１により駆動される第２油圧ポンプ１２と、潤滑対象に対して油Ｆを供給する第１供給油路３１と、係合装置Ｃ０，Ｃ１に対して油圧を供給する第２供給油路３２と、第１油圧ポンプ１１と第１供給油路３１とを接続する第１接続油路４１と、第２油圧ポンプ１２と第２供給油路３２とを接続する第２接続油路４２と、第１接続油路４１と第２接続油路４２とを接続し、途中に第１逆止弁５１が設けられた第３接続油路４３と、を備え、第１分岐部４１ａよりも下流側に制御弁６が設けられ、制御弁６は、係合装置Ｃ０，Ｃ１の係合動作中、第１接続油路４１における制御弁６よりも上流側の油圧を、第２接続油路４２の油圧よりも高くする。【選択図】図２
