Abstract
An electronic throttle control mechanism having a housing and cover member with a throttle valve, gear mechanism, motor, and failsafe mechanism. The housing, cover member and other components are made of a plastic composite material. A spring member positioned between the housing and sector gear member which is attached to the throttle valve shaft, biases the throttle valve plate member toward the closed position. A spring-biased plunger member biases the throttle plate member from its closed position to a default or “limp-home” position. A metal reinforcing plate is molded into the cover member in order to keep the gears in alignment and maintain proper gear positioning during high temperature fluctuations.
