    摘要: An air induction valve adapted to introduce controlled amounts of additional air to the combustion chamber of an automotive engine when engine vacuum is low, which includes a hollow cylindrical casing having a chamber in communication with the intake manifold of the engine and with ambient air. A pair of perforated partition plates are disposed in parallel spaced apart relationship in the casing, with value means being provided between the partition plates, the valve means being vertically moveable between the plates in response to engine vacuum. Compression springs are provided between the valve means and the partition plates, with the valve means being normally biased open. When the automotive engine is operating under conditions resulting in high engine vacuum, the valve means is displaced to prevent the flow of ambient air through the air induction valve. When the engine is operating under conditions resulting in a low engine vacuum, the valve means is urged to an open position to provide an annular air passage around the valve means and permit the introduction of controlled amounts of ambient air through the air induction valve into the combustion chamber to provide a more efficient air-fuel mixture under such conditions.
