Integrated VDA housing with anti-rotation feature
A throttle control assembly which includes a throttle body housing, an adapter integrally formed with the throttle body housing, a housing portion being part of the adapter, and a central port which extends through the throttle body housing and the adapter. A first groove is integrally formed as part of the adapter, a second groove is integrally formed as part of the throttle body housing, and a rib portion disposed between the first groove and the second groove. The rib portion is formed as part of the adapter, and an anti-rotation feature is integrally formed with the throttle body housing. The anti-rotation feature is integrally formed with the throttle body housing during a molding process. The anti-rotation feature may be formed in different locations on the outer surface of the housing, allowing the throttle body assembly to be suitable for various applications having different design and packaging requirements.
