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.

Dependent claims

An air intake damper, comprising:

a first air intake conduit having a first longitudinal axis, an upstream end and a downstream end, the first air intake conduit having a first intake area, wherein the first intake area is substantially perpendicular to the first longitudinal axis, and
a plurality of partitions extending across the first intake area in a vertical direction, wherein each partition has at least an upstream end and a downstream end as well as at least one of a first surface and of a second surface,
where in a first position
two adjacent partitions are positioned to define a first fluid communication channel having an upstream end and a downstream end, and extending along the first air intake conduit, wherein the fluid communication channel in a direction extending along the first longitudinal axis has at least one bend so that any imaginary straight line extending from the upstream end to the downstream end will intersect at least one of an inner surface and an outer surface of at least one partition, and
where in a second position
two adjacent partitions are positioned to prevent fluid communication between the upstream end and the downstream end of the first air intake conduit.
