Abstract
A throttle body includes a secondary passageway having an inlet communicating with a central passageway upstream of a throttle plate disposed in the central passageway. An outlet communicates with an intake manifold of the engine downstream of the throttle plate to allow fluid flow to bypass the throttle plate. A pocket is formed in the throttle body and a seat is formed at the bottom of the pocket to communicate with the secondary passageway. A motor is disposed within the pocket and secured to the throttle body and cooperates with the seat for metering predetermined amounts of fluid flow past the seat. An opening is formed intersecting with the pocket and the outlet to form an internal flow path within the throttle body to allow fluid flow past the seat to flow through the outlet and bypass the throttle plate when in the closed position.
