<p>PROBLEM TO BE SOLVED: To provide an oil pump system capable of effectively reducing fuel consumption.SOLUTION: An oil pump system 10 adjusts oil to two kinds of oil pressure during an operation of an automobile 1, and feeds the oil. A system main body 11 has a mechanical pump 5, an electric pump 6, an oil pan 7, a high pressure regulator 13, and a low pressure regulator 14. A system control part 12 switches the system between a first control for pressurizing the oil only by the mechanical pump 5, adjusting the oil to a high pressure value and a low pressure value by both of the high pressure regulator 13 and the low pressure regulator 14, and feeding it; and a second control for pressurizing the oil by both of the mechanical pump 5 and the electric pump 6, adjusting the oil pressurized by the mechanical pump 5 by the low pressure regulator 14, adjusting the oil pressurized the electric pump 6 by the high pressure regulator 13, and feeding it.</p> |
