ABSTRACT:
An air throttle (10) for an internal combustion engine has a butterfly-vane (16) mounted for rotation in the engine charge air inlet (15). The butterfly-vane is mounted on a rigid tubular shaft (18) having an idle air bleed slot (22) therethrough with a tubular idle valve (24) slip fit within the shaft for concentric rotation therein. With the butterfly-vane closed for idle mode running, the idle valve is rotated between set limits established by abutment surfaces (26) and (36) defined by slot (25) to control idle air flow and idle speed. Upon rotation of the idle valve beyond the set limits, the butterfly-vane is progressively opened for off-idle mode running speed control.
