ABSTRACT:
The throttle blade is made to have a resilient outer margin whose outside diameter is circular and essentially equal to the diameter of the throttle bore within which the blade is disposed. The blade can maintain control even at engine idle. Several embodiments of throttle blade are disclosed. In one, an elastomeric seal is insert-molded onto the main blade body; in another, the seal is a multitude of short bristles; in still another, it is a stamped polytetrafluoroethylene part. There is also a special construction for assembling the shaft.
