<P>PROBLEM TO BE SOLVED: To provide an oil supply system of a transmission that supplies oil from an oil reservoir to a high-pressure part for operating a clutch and a low-pressure part for cooling and lubricating using an oil pump. <P>SOLUTION: The oil supply system includes a first oil pump pumping up oil from the oil reservoir and supplying the oil to the low-pressure part; a low-pressure regulating valve connected to a low-pressure part channel connecting the first oil pump with the low-pressure part, and controlling the pressure of the oil discharged from the first oil pump at pressure required by the low-pressure part; a second oil pump receiving the oil the pressure of which is controlled through the low-pressure regulating valve, and supplying the oil to the high-pressure part; and a high-pressure regulating valve connected to a high-pressure part channel connecting the second oil pump with the high-pressure part, and controlling the pressure of the oil discharged from the second oil pump at pressure required by the high-pressure part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
