An ECU (200) controls the current in a valve-opening coil (572) and a valve-closing coil (562) so that an electromagnetically driven valve (500), which is actuated by the electromagnetic force generated by the valve-opening coil (572) and the valve-closing coil (562) and the elastic force of a spring (518), is switched from the opened state to the closed state or from the closed state to the opened state (S300), and after the electromagnetically driven valve (500) has been switched to the opened state or the closed state, the ECU (200) controls the current in the valve-opening coil (572) and the valve-closing coil (562) so as to increase at a timing according to the cycle of surging of the spring (518). |
