Disclosed is an oil pressure supply system of an automatic transmission for a vehicle. According to an embodiment of the present invention, the oil pressure supply system of an automatic transmission for a vehicle comprises: a low pressure oil pump which is driven by an engine, changes oil stored in an oil pan into low pressure oil, and discharges the low pressure oil to a first low pressure flow path; a high pressure oil pump which is driven by an electric motor, boosts the pressure of a part of the low pressure oil from the first low pressure flow path to high pressure, and discharges the high pressure oil to a first high pressure flow path; a low pressure regulator valve which controls the pressure of the oil while discharging a part of the oil supplied through the first low pressure flow path and supplies the oil to a low pressure unit through a second low pressure flow path; and a high pressure regulator valve which controls the pressure of the oil while recirculating a part of the oil supplied through the first high pressure flow path in the low pressure unit through a recirculation flow path according to the pressure of the oil or recirculating the oil in the low pressure unit through two recirculation flow paths and supplies the oil to a high pressure unit through a second high pressure flow path.

    차량용 자동변속기의 유압공급시스템이 개시된다. 본 발명의 일 실시 예에 따른 차량용 자동변속기의 유압공급시스템은 엔진에 의하여 구동되면서 오일팬에 저장된 오일을 저압의 유압으로 생성하여 제1 저압유로로 토출하는 저압용 오일펌프; 전동모터에 의하여 구동되면서 상기 제1 저압유로의 유압 일부를 고압으로 승압시켜 제1 고압유로로 토출하는 고압용 오일펌프; 상기 제1 저압유로를 통해 공급되는 유압의 일부를 배출하면서 유압을 조절하여 제2 저압유로를 통해 저압부로 공급하는 저압용 레귤레이터 밸브; 및 상기 제1 고압유로를 통해 공급되는 유압의 일부를 그 압력에 따라 하나의 재순환 유로를 통해 저압부로 재순환시키거나, 두 개의 재순환 유로를 통해 저압부로 재순환시키면서 유압을 조절하여 제2 고압유로를 통해 고압부로 공급하는 고압용 레귤레이터 밸브를 포함한다.
