Flow-rate control valve actuator

Problem

How can vibration in electric motors and rotors be reduced?

Solution

flow-rate control valve 10 a includes: a housing including a valve body configured to regulate an opening degree of a flow channel to be reciprocable, formed therein; a driving force transmission mechanism 31 provided in the housing and including a valve driving shaft driving a valve body, a hollow screw shaft 40 screwed to the valve driving shaft and a rotator 36 configured to rotate the hollow screw shaft 40 ; and a drive mechanism 53 including actuators 54 and 55 with a piston 61 embedded therein, the piston 61 is provided with a lever 66 engaged with engaging sections provided on the rotator 36 , and the rotator 36 is rotated to a constant angle through the lever 66 by reciprocation of the piston 61 to regulate the opening degree of the flow channel by the valve body.

Key novelty

Active control systems is reinforced by front-page matches on actuator.
