Document Type and Number:
Japanese Patent JP2015057559
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a hydraulic supply system of an automatic transmission for a vehicle that supplies to a low-pressure part and a high-pressure part hydraulic pressure generated by an oil pump having two pump chambers, and performs mode transformation to a two-circuit mode or a half delivery mode by surplus hydraulic pressure of the high-pressure part and low-pressure part in a total delivery mode.SOLUTION: A hydraulic supply system of an automatic transmission for a vehicle can supply hydraulic pressure, generated by an oil pump including first and second pump chambers formed inside the system, to a high-pressure part and a low-pressure part of the automatic transmission through a high-pressure regulating valve, first and second switch valves, and a low-pressure regulating valve.
