Abstract
In an air intake assembly, a portion of an inner peripheral wall of an intake funnel pipe is provided as a pivotally movable blocking body, so that when unthrottled, an inner wall surface of the blocking body is flush with the inner peripheral wall of the funnel pipe. The blocking body has a substantially trianglular outline shape, the apex of which is positioned on top when viewed along the axis of the support shaft. The support shaft is positioned at the apex of the blocking body, and allows pivotal movement of the blocking body, on the downstream side thereof, to allow adjustment of the rate of air flow through the funnel pipe. The blocking body within the funnel pipe of an air intake assembly allows a smooth flow of air therepast when actuated to throttle the air intake channel, and does not obstruct the air intake channel when inactive.
