Conventional oil pumps cannot be used when the pressure and the temperature are high. In this oil pump (1), two rotors (6, 7) are connected in series in the direction of the axis of rotation. The rotors (6, 7) are housed separately with a spacer (5) therebetween within a rotor case (4), and the interior of the rotor case is partitioned by mean of the spacer (5). The rotor case (4) forms a cylindrical shape, and the spacer (5) is integral with the rotor case (4). The rotors (6, 7) and the rotor case (4) are iron-based, and are affixed to a housing (2) by means of positioning pins. |
