Abstract
An automotive air control valve comprises a housing, the housing defining an air flow path, a blade pivotally mounted within the housing, the blade pivotable between a closed position, wherein the blade substantially blocks air flow through the housing, and an open position, wherein air can flow through the housing, an actuator adapted to selectively pivot the blade between the open and closed positions, a first stop that provides a positive stop for the blade when rotated to the open position, a second stop that provides a positive stop for the blade when rotated to the closed position; and an over-center cam mechanism, wherein the over-center cam mechanism is adapted to bias the blade in the open position when the blade has been pivoted to the open position, and to bias the blade in the closed position when the blade has been pivoted to the closed position.
