Apparatus for controlling throttle shaft deflection and friction in dual bore throttle bodies

摘要

A throttle body for an automobile includes a housing defining a plurality of bores separated by a central wall. A passageway is defined through the central wall. A shaft is rotatably received within the passageway. A plurality of plates is coupled with the shaft. A contacting preventing means is configured to selectively engage the shaft upon deflection of the shaft in the region of the central wall to prevent contact between the shaft and the housing.
