Valve assembly for air duct system of automobile internal combustion engine, has detent unit fixed to control shaft to which valve is attached, where detect unit has lug that is pressed against stop plate when air stream flows into system

摘要

The assembly has a valve (10) attached with a control shaft (12). A detent unit (18) with a lug (30) is attached to the shaft. An actuator actuates the detent unit to move in axial direction of the shaft so that the lug is pressed against a stop plate (32) when the air stream flows into an air duct system. A projection of the detent unit is aligned within a slot of the actuator when the valve is in a disengaged position.
