Abstract

PURPOSE: To simplify the structure and to hold the valve at the middle of opening by rotatably providing the braking shaft which is sequential to the gear train and connecting the solenoid of the brake, which is mounted on the braking shaft, to the motor in parallel.
CONSTITUTION: When the motor 3 is driven, the output shaft 6 is turned through the driving valve 4 and the gear train 2, and the valve operates the expected open- close motion. On the other hand, accompanied by the driving of the motor 3, the solenoid 12 of the braking mechanism 7 is activated upward and presses the spring 16 through the shaft 14. At the same time, as clamping of the shaft 14 and the pressing plate 20 are released, the braking shaft 8 which is clamped with the gear train 2 through the pinion 9 is turned smoothly. When the motor 3 is stopped, the brake plate 18 fixed in the middle of the brake shaft 8 is tightly held between the pressing member 20 and the bearing 17 through the sliding plate 19 by the spring 16, so that the rotation of the braking shaft 8 is stopped, and furthermore, the rotation of the output shaft 6 is stopped through the pinion 9 and the gear train 2.
