<p><P>PROBLEM TO BE SOLVED: To provide a lubricating oil supply device for reducing a cost, by simplifying hydraulic passage structure while preventing generation of negative pressure between an oil pump and an electric pump. <P>SOLUTION: The lubricating oil supply device comprises: an oil pan 20 storing lubricating oil; an oil pump 22 sucking the lubricating oil from the oil pan and discharging the lubricating oil to a discharge passage 24; and an electric pump 25 sucking the lubricating oil, which is discharged from the oil pump to the discharge passage, and discharging the lubricating oil to lift variable mechanism of an engine or each sliding part. A check valve 39 is disposed to a bypass passage 37 bypassing the oil pump to make the lubricating oil in the oil pan flow into a discharge passage side when a discharge amount of the electric pump is larger than the oil pump. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
