Claims

[Scope of utility model registration request]

Output shaft 2 connected to the rotating shaft of the valve body of valve A
In the valve actuator 1, the valve A is rotated 90 degrees in the forward and reverse directions by a reversible rotary motor 3 to open and close the valve A. A plate 7 that pivots on a rotating shaft 4, and a gear 6 that meshes with a gear 5 that is integrally fixed to the rotating shaft 4, is pivoted on a shaft ₆₁ .
The internal teeth 8 are pivotally supported on the same rotating shaft and mesh with the gear 5.
₁ ... 8 ₁ is integrally fixed to the output shaft 2, and internal teeth _{9 1} having a different number of teeth from the number of teeth of the internal gear 8, which meshes with the same gear 5 in common. A valve actuator comprising an internal gear 9 provided with 9 ₁ , which is pivotally supported on a rotating shaft 4, and a regulating member 10 that prevents rotation of the internal gear 9.
