| description | PROBLEM TO BE SOLVED: To prevent deficiency of oil discharge rate at one oil pump of a pair of oil pumps even in a state where an oil circulation circuit is composed of another oil pump of an oil supply device for internal combustion engine in which an inlet common to a first and second oil pumps is installed on a pump casing common to the first and second oil pumps with a common pump shaft, and a first and second relief valves are connected individually to discharge paths of the first and second oil pumps.SOLUTION: An inlet 139 is divided into a first and a second inlets 141, 142 by a partition wall 140. A first intake path 143 which reaches from the first inlet 141 to an intake side of the first oil pump 115 and a second intake path 144 which reaches from the second inlet 142 to the intake side of the second oil pump 116 independent from the first intake path 143 are formed on the pump casing. Outlets 150, 166 of the first and second relief valves 147, 163 are connected to the second intake path 144. |
