Abstract
PURPOSE: To save energy required for operating a combustion controlling apparatus, by empolying an arrangement that a power source is connected only at the time of opening and closing a valve and the power source is disconnected automatically in a stable state of the valve by means of a motor and associated switches having a high operating hysteresis.
CONSTITUTION: In the state that a selector switch 14 is shifted to the side of contact point C, a motor 11 is not rotated further since connection to the power source is interrupted, if a dual switch 16, 17 for closing a vavle 4 is closed. Therefore, the motor 11 is stopped, keeping the valve 4 closed. On the other hand, when it is wanted to open the valve 4, another dual switch 18, 19 for opening valve 4 is closed. Thereupon, dual switch 16, 17 associated with the dual switch 18, 19 is opened and polarity for supplying current to motor 9 is inverted, which causes counterclockwise rotation of motor 11 and upward movement of a rack 10. Since selector switch 14 is shifted to the side of contact point D when the valve 4 is closed, motor 11 is not rotated further since connection to the power source is interrupted, so that it is stopped, keeping the valve 4 open.
