Claim:
A charge motion control valve assembly for use in a V-type engine having first and second cylinder banks, said valve assembly comprising: a) a manifold for mounting to a V-type engine, said manifold having a plurality of air inlets extending in generally linear fashion into an axially extending central bore, a first plurality of air outlets extending generally radially from said bore and directed toward said first cylinder bank, and a second plurality of air outlets axially interspersed with each alternating outlet of said first plurality of outlets, extending generally radially from said bore and directed toward said second cylinder bank with an azimuthal angle defined between said first plurality of outlets and said second plurality of outlets; b) a single elongated barrel valve coaxially and rotatably mounted in said manifold bore between said plurality of respective air inlets and air outlets, said barrel valve having a first plurality of passages therethrough between a first plurality of inlet openings and a first plurality of outlet openings, and a second plurality of passages therethrough having a second plurality of inlet openings and a second plurality of outlet openings axially interspersed with each alternating passage of said first plurality of passages, having an azimuthal angle between said first and second pluralities of outlet openings generally corresponding to said azimuthal angle between said first plurality of outlets and said second plurality of air outlets wherein each passage is arranged to axially align with one air inlet and one air outlet; whereby said barrel valve is rotatable between a fully open position with said inlet and outlet openings being simultaneously and fully aligned with each respective pair of air inlets and air outlets to allow unimpeded air flow therethrough, and a fully closed position with said inlet and outlet openings being simultaneously and fully out of alignment with each respective pair of air inlets and air outlets to substantially prevent air flow therethrough.
