主权项

1. A swirl vane air duct cuff assembly comprising:
a tubular body; and a swirl vane cuff extending from said tubular body, said swirl vane cuff over-molded to an end of said tubular body, said swirl vane cuff having an exterior surface which has a cuff groove, and an interior surface which has a plurality of vanes inwardly and integrally extending therefrom, each said vane having a base directly extending from said interior surface, and each said vane having a leading edge and a trailing edge opposite each other to form a contoured airflow surface that imparts a swirling motion to an airflow moving from said tubular body through said swirl vane cuff, wherein each said leading edge and each said trailing edge of an adjacent vane form a vane gap therebetween without overlapping one another when the assembly is viewed axially.
