Abstract
An idle air control valve for a vehicle includes a housing (21), a motor (32) disposed in the housing, a shaft (29) associated with the motor, and a bellows assembly (30) including a bellows structure (10) having a first end defining a base (14), a second, opened end (16), and a bellows (18) between the first and second ends. An annular rim member (28) is associated with the second opened end. A pintle (24) has surfaces defining an annular groove (26) therein. The annular rim member (28) is received, in press-fit engagement, in the annular groove (26). The base (14) is in press-fit engagement with a recess (22) in the housing and the pintle (24) is coupled with an end of the shaft, such that the bellows structure together with the pintle surround the shaft and provide a barrier substantially preventing contaminants from entering the motor.
