  • Publication number: 20090001308
    Abstract: A valve to shaft assembly includes a butterfly-type valve, a pair of bushings receiving the valve and holding the valve in axial position within a housing, and a shaft engaging the valve and the bushings and rotating the bushings in the housing. The bushings include features to hold the valve in position in the bore prior to assembly of the valve and, furthermore, act as rotating bearing surfaces for the valve. The valve to shaft assembly process may be simplified, especially where multiple valves are assembled to a single common drive shaft, such as in a port face charge motion control valve. Furthermore, the valve to shaft assembly provides an axial degree of freedom between valve, drive shaft, and bore, which allows the valve to float on the axis of the drive shaft, to facilitate self centering of the valve in the valve housing.
