Abstract
An exhaust gas control valve includes a housing having an interior wall defining a housing interior, a pinion gear coupled to the housing and configured to be rotatably driven, and a helical gear configured to receive torque from the pinion gear and including a plurality of helically arranged teeth. The exhaust gas control valve also includes a valve member disposed at least partially in the housing interior of the housing. The valve member includes a valve shaft extending along an axis and having first and second shaft ends, and a valve body coupled to the valve shaft adjacent to the second shaft end and moveable with the valve shaft along the axis between a first valve position and a second valve position. The exhaust gas control valve further includes a motion converter configured to convert rotational motion of the helical gear to linear motion of the valve member.
