摘要： An actuator includes an electric motor and a drive force transmitting mechanism. The drive force transmitting mechanism includes a rotary gear and a rotary cam. The rotary gear transmits a drive force of the electric motor to an EGR valve to drive the same. The rotary cam transmits the drive force of the electric motor to a mode change valve to drive the same. The rotary cam is releasably linkable to the rotary gear to receive the drive force of the electric motor through the rotary gear.

摘要： When a valve body is rotated toward a full-close position in a valve-close mode, a control portion controls an electric motor so that the rotating speed of the valve body is lower than that in a valve-open mode. A rotating speed of the valve body around the shaft in the valve-close mode is lower than that in the valve-open mode. Thus, when the seal ring is brought into contact with the inner wall surface, an impact generated therebetween can be moderated. While the valve body is rotated toward the full-close position, a seal ring is gradually elastically deformed. A sliding friction between the seal ring and the inner wall surface can be reduced.
摘要翻译： 当阀体在闭阀模式下向全闭合位置旋转时，控制部分控制电动机，使得阀体的转速低于阀打开模式。 在阀关闭模式下，阀体围绕轴的转速低于阀打开模式。 因此，当密封环与内壁表面接触时，其间产生的冲击可以缓和。 当阀体朝向完全关闭位置旋转时，密封环逐渐弹性变形。 可以减小密封环与内壁面之间的滑动摩擦。
