Abstract
An electronic throttle body uses a spring and an insert to generate a force tending to oppose the motion of opening a throttle. The insert locates and centers the coils of the spring and also acts during assembly to place the proper amount of torsion on the spring and the throttle body system. Once a throttle body motor or other force ceases to exert force against the spring, the spring causes the throttle to close.
