Abstract
A first check valve of a hydraulic control system allows oil to flow in only a direction from a first oil pump toward an oil receiving portion. A second check valve allows oil to flow in only a direction from a second oil pump toward the oil receiving portion. A third oil passage is configured to provide communication between a merging point of a first oil passage and a second oil passage, and the second oil pump by bypassing the second check valve. The third oil passage includes a throttle mechanism. The third oil passage is configured to restrict a flow rate of oil that is discharged from the second oil pump.
