Abstract
PURPOSE:To arbitrarily set and hold the valve opening degree by installing an operating switch for the opening degree of an opening/closing valve and a solenoid for holding the valve opening degree. CONSTITUTION:The series circuit 10 for a motor 5 which is equipped with a main switch 12 is further equipped with the first limit switch 22. 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. When the opening/closing valve is opened to a set opening degree, the second limit switch 22 is connected with a contact point (d), and the motor 5 is stopped. At this time, 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 a magnetic force is generated on the solenoid 8 for holding the valve opening degree, and the gear of the motor 5 is applied with a stop force.
