Abstract
PURPOSE:To keep a valve at a desired opening degree by exciting a solenoid for holding the valve opening degree, when a valve opening degree operating switch is set at a neutral position. CONSTITUTION:The series circuit 10 for a motor 5 which is equipped with a main switch 12 and an opening/closing valve opening degree switch 17 is connected with an electric power source 11. When an opening/closing valve is opened, the main switch 12 is closed to revolve the motor 5. At this time, the first relay circuit 13 is in conduction state, and a solenoid 8 for holding the valve opening degree is in nonconduction state, and an electromagnetic lock circuit 18 does not apply a stopping force onto the motor 5. When the opening/closing valve is opened to a desired opening degree, the operating switch 17 is set at a neutral position. Therefore, the motor 5 is stopped, and the B- contact point 19 of the first relay coil 14 and the B-contact 20 of the second relay coil 16 are closed, and the electromagnetic lock circuit 18 conducts, and the solenoid 8 for holding the valve opening degree is excited.
