摘要： PROBLEM TO BE SOLVED: To provide a hydraulic control circuit of a vehicular power transmission apparatus which prevents intake of air from an oil delivery/oil supply side even when an oil pump rotates reversely, and prevents foreign matter accumulated in an oil strainer from being diffused into oil.SOLUTION: When an oil pump 120 rotates reversely, operating oil of a second oil passage 132 is inhaled from a second port 128 side of the oil pump, and discharged to a first oil passage 126 side from a first port 124, but a first check valve 136 is closed then, and the operating oil discharged to the first oil passage 126 passes through a third oil passage 134 and flows into the second oil passage 132 through a third check valve 140. Since a second check valve 138 is closed, the operating oil never flows (flows reversely) to the second oil passage 132 side from a lubricating oil passage 130 side, whereby intake of air from the lubricating oil path 130 side is prevented.

摘要： PROBLEM TO BE SOLVED: To provide a vehicular oil pump, driven by a rotation shaft in which a rotation direction when a vehicle goes forward is reversed to a rotation direction when the vehicle goes backward, capable of supplying oil whether the vehicle goes forward or backward, and having a simple structure.SOLUTION: When the vehicle goes forward, a first driven gear 168 drives a pump shaft 158 of the oil pump 120 via a first one-way clutch 166 to drive the oil pump 120. When the vehicle goes backward, a second driven gear 172 drives the pump shaft 158 of the oil pump 120 via a second one-way clutch 170 to drive the oil pump 120. By this, an oil-pressure requiring part of the vehicle can be supplied with the oil regardless of the travelling direction of the vehicle. In addition, as a special switching mechanism, etc., for switching an oil passage according to the travelling direction of the vehicle is not necessary, the device becomes simple, and manufacturing cost can be suppressed.
