PROBLEM TO BE SOLVED: To provide a control device for an electromagnetic actuation valve capable of securing an opening area during suction and exhaust while preventing the interference of the electromagnetic actuation valve and a piston. SOLUTION: The electromagnetic actuation valve 40 is provided in such a manner that the valve can be opened at two kinds of openings of small lift and normal lift, and ECU 80 is provided with an interference determination part 87 determining whether an interference region which is a region where a valve element 45 and a piston 8 interferes when the electromagnetic actuation valve 40 is opened at normal lift. Consequently, the opening area during suction and exhaust can be made wide by opening the electromagnetic actuation valve 40 at normal lift in a normal state, and the interference of the valve element 45 of the electromagnetic actuation valve 40 and the piston 8 can be prevented by opening the opening area at small lift when an interference region is included if the opening area is opened at normal lift. As a result, the opening area during suction and exhaust can be secured while preventing the interference of the electromagnetic actuation valve 40 and the piston 8. COPYRIGHT: (C)2008,JPO&INPIT
