Document Type and Number:
Japanese Patent JP2016098953
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a movable valve mechanism of an actuator in an engine, capable of preventing resonance with the engine.SOLUTION: A movable valve mechanism is used in a waste gate valve 60 that includes energization means of: rotatably driving a drive gear 70 with a drive motor 55; advancing/retreating a valve shaft 65 screwed into the drive gear 70 by rotatably driving the drive gear 70, in an axial direction; moving a valve 61 provided in the valve shaft 65, from a valve sheet 62 by advancing/retreating the valve shaft 65, thereby to open/close a flow passage 82; and energizing the valve 61 toward an opening direction. The energization means comprises a first spring 91 and a second spring 92 arranged in series through a plate 66.SELECTED DRAWING: Figure 2
