Abstract

A hydraulic pressure supply system includes a mechanical oil pump, an electric oil pump, a first flow path, a second flow path, and a cut-off mechanism. The mechanical oil pump is configured to operate by power from an engine. The electric oil pump is configured to operate by power from a motor. In the first flow path, oil supplied from the mechanical oil pump and the electric oil pump flows, the first flow path being coupled to the mechanical oil pump and the electric oil pump. The second flow path branches off from the first flow path and is configured to cause an oil to return to an oil pan via a torque converter. The cut-off mechanism is configured to close off the second flow path by oil delivered from the electric oil pump.
