IMPROVED REED VALVE AND REED VALVE AIRBOX

A reed valve includes a first valve body portion that includes one or more inlet apertures fluidly coupled to a tapered second valve body portion that includes one or more outlet apertures. The reed valve includes at least one sealing surface disposed proximate the one or more outlet apertures and at least one petal continuously, reversibly, displaceable between an OPEN position permitting forward flow through the reed valve when a fluid pressure proximate the at least one inlet aperture exceeds a fluid pressure proximate the at least one outlet aperture and a CLOSED position preventing reverse flow through the reed valve when a fluid pressure proximate the at least one outlet aperture exceeds a fluid pressure proximate the at least one inlet aperture. The reed valve may be installed in an airbox assembly used with a turbocharged engine to reduce the occurrence of turbo-lag on acceleration.
