A control system for an electromagnetic valve having a valve element, a pair of solenoids opposed to each other and disposed to drive the valve element in respective directions opposite to each other and between a first extreme position and a second extreme position, and a spring interposed between the solenoids, for biasing the valve element toward a neutral position intermediate between the first and second extreme positions. The solenoids are controlled such that when the valve element is to start moving from one of the first and second extreme positions toward the other extreme position, energization of a corresponding one of the solenoids is terminated, and energization of the other solenoid is started when a predetermined delay time period elapses from the termination of the corresponding one solenoid. The solenoids are also controlled such that they are both energized over a predetermined lap time period during movement of the valve element from one of the first and second extreme positions toward the other extreme position.
A control system for an electromagnetic valve having a valve element, a pair of solenoids opposed to each other and disposed to drive said valve element in respective directions opposite to each other and between a first extreme position and a second extreme position, and spring means interposed between said solenoids, for biasing said valve element toward a neutral position intermediate between said first and second extreme positions, the control system comprising:
