CONSTITUTION: A valve actuator for hot water distributor for heating room comprises a motor(120), an outer gear(130), an inner gear(140), a rotating material(150) and an elevator(160). The outer gear is fixed and combined in the motor shaft of the motor and is rotated according to the driving of the motor. The internal gear forms a penetrated hole in the central part. The toothed gear engaging between the outer circumference toothed gears in the inner circumference of the penetrated hole is formed. According to a horizontal movement, a locking or unlocking is actuated. The rotator forms an eccentric cam(154) in the outer circumference. One side is combined with the internal gear and is revolved with the internal gear. |
