TIRE AIR INTAKE FILTER

摘要

A tire air intake filter includes a housing to be attached to a sidewall of a self-inflating pneumatic tire. The housing has a cavity to be in fluid communication with an atmospheric air inlet of a pneumatic control valve for the self-inflating tire. A filter media is to block contaminants from entering the cavity while allowing atmospheric air to be drawn through the filter media into the cavity by a pump of the self-inflating tire. The filter has an elliptical profile having a minor axis and a major axis. The minor axis is to be aligned with a radius of the tire. A self-inflating tire having the air intake filter is also disclosed.
