<P>PROBLEM TO BE SOLVED: To provide a device capable of easily setting or adjusting the hysteresis of the opening/closing timings of a selector valve selectively communicating/cutting out the delivery ports of two oil pumps. <P>SOLUTION: This control device of the multiple pumps comprises a first oil passage 3 communicating with the first oil pump, a second oil passage 12 communicating with the second oil pump, and the selector valve 13 selectively opening/closing an opening part 17 between the first oil passage 3 and the second oil passage 12. The selector valve 13 comprises a valve element 21 disposed on the first oil passage 3 side in the opposed state parallel with or diagonally to the opening part 17. When the delivery amount of the second oil pump is larger than the delivery amount of the second oil pump when the valve element 21 closes the opening part 17, the valve element 21 opens the opening part. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
