An oil pressure supply system of an automatic transmission for a hybrid vehicle is disclosed. The oil pressure supply system of an automatic transmission for a hybrid vehicle pumps oil stored in an oil pan from an oil pump to oil pressure with high pressure and supplies oil to a high pressure portion and a low pressure portion. In addition, separate motor/generator cooling routes can be included to use a flow rate which is recirculated in a line regulator valve and a flow rate which is recirculated in a reducing valve as cooling oil for a motor or a generator. The line regulator valve controls the oil pressure supplied from the oil pump to a line pressure with high pressure and supplies the oil pressure to a high pressure portion and a low pressure portion. The reducing valve decompresses and controls the oil pressure supplied from the line regulator valve to the low pressure portion so as to supply the oil pressure to a cooler.

    하이브리드 자동차용 자동변속기의 유압공급시스템이 개시된다. 본 발명의 실시 예에 따른 하이브리드 자동차용 자동변속기의 유압공급시스템은 오일 팬에 저장된 오일을 오일펌프에서 고압의 유압으로 펌핑하여 고압부 및 저압부로 공급하는 하이브리드 자동차용 자동변속기의 유압공급시스템에 있어서, 상기 오일펌프로부터 공급되는 유압을 안정된 고압의 라인압으로 제어하여 고압부와 저압부로 공급하는 라인 레귤레이터 밸브에서 재순환되는 유량과, 상기 라인 레귤레이터 밸브로부터 저압부로 공급되는 유압을 감압 제어하여 쿨러로 공급하는 리듀싱 밸브에서 재순환되는 유량을 모터/제너레이터의 냉각 오일로 사용할 수 있도록 별도의 모터/제너레이터 냉각 루트를 포함할 수 있다.
