Abstract
A self-cleaning duct assembly. The self-cleaning duct assembly includes a hollow member having an inner surface, the inner surface defining a central axis and a flow passage for directing a fluid flow along the central axis. The self-cleaning duct assembly also includes a resilient member including a plurality of arcuate segments disposed along the central axis, each of the arcuate segments spaced from the inner surface. The arcuate segments intermittently contact the inner surface as the resilient member is induced to move within the hollow member.
