ABSTRACT:
Induction air flow to an internal combustion engine is controlled or measured by a butterfly valve which extends into undercut recesses on opposite sides of the valve bore. The valve member rotates in excess of 90.degree. between its minimum air flow position and its maximum air flow position and offers a relatively low normalized change in the flow area around the valve.
