クチユエータ。 A rod actuator that does not require a piston rod converts the linear motion of a piston that reciprocates in sliding contact with the inner wall of a cylinder into the rotational motion of a yoke and a drive shaft to which the yoke is attached. It is composed of an intermediate rib that sandwiches the hollow part and integrally connects both sliding contact parts, and the trunnion pin attached to the intermediate rib and the drive shaft connected to the butterfly valve are moved to the opposite side of the axis of the cylinder. At the same time as making the drive shaft eccentric, the drive shaft is passed through the hollow part of the piston and attached to the cylinder,
The yoke groove of the yoke fixed to the drive shaft is inclined with respect to the yoke center line connecting the drive shaft axis and the trunnion pin axis, and the trunnion pin is engaged with this yoke groove, and the drive shaft is moved by the reciprocating movement of the piston. A rotary actuator for driving a butterfly valve, characterized in that the yoke is long enough to prevent the tip of the yoke from interfering with the cylinder when the yoke swings, and the cylinder is shaped like a straight cylinder. .
