摘要： A hydraulic pressure supply system of an automatic transmission for a vehicle is provided. The system divides a hydraulic pressure generated from first and second pump chambers of a hydraulic pump into a high-pressure and low-pressure part. The system includes first and second input lines that guide oil of an oil pan to the first and second pump chambers. First and second discharge lines discharge the hydraulic pressure generated from the first and second pump chambers. A high-pressure switch valve selectively supplies or recycles the hydraulic pressure supplied from the first discharge line to the high-pressure hydraulic path into the high-pressure part. A pressure accumulator is disposed on a high-pressure hydraulic path between the high-pressure switch valve and the high-pressure part and a low-pressure switch valve selectively supplies or recycles the hydraulic pressure supplied from the second discharge line to the low pressure hydraulic path into the low-pressure part.
