<p><P>PROBLEM TO BE SOLVED: To provide a control circuit etc. for controlling an electromagnetic valve, the circuit size of which is smaller than that of a conventional one. <P>SOLUTION: The control circuit for controlling an electromagnetic valve comprises a solenoid that operates the electromagnetic valve, a capacitor, a switching means for switching connection relationships, and a switching control means for controlling switching of connection relationships. The solenoid, the capacitor, and the switching means are connected in order. The switching control means is connected in parallel to the solenoid, the capacitor, and the switching means. A power source that provides electricity is connected in parallel to the solenoid, the capacitor, and the switching means. The switching control means switches between a closed circuit that controls the switching means, includes the power source, the solenoid, the capacitor, and the switching means, and provides electricity to the solenoid and stores electricity in the capacitor and a closed circuit that does not include the power source or the switching control means but includes the solenoid, the capacitor, and the switching means, and provides electricity to the solenoid by the discharge of the capacitor. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
