Air intake damper

Abstract

There is an air intake damper. The damper has a first air intake conduit having a first longitudinal axis and having an upstream end and a downstream end. The first air intake conduit has a first intake area, in which the first intake area is substantially perpendicular to the first longitudinal axis. Partitions extend across the first intake area, in which each partition has at least an upstream end and a downstream end and has an first surface and/or an second surface. In a first position, two adjacent partitions are positioned to define a first fluid communication channel having an upstream end and a downstream end extending along the first air intake conduit. The fluid communication channel in a direction extending along the first longitudinal axis has at least one bend so that an imaginary straight line extending from the upstream end to the downstream end will intersect at least the first surface and/or the second surface of at least one partition.
