Abstract
A hubcap breather assembly is provided for a hubcap housing lubricated wheel bearings in an automotive vehicle. The breather assembly includes a resilient, annular collar that fits into an access opening in a hubcap end wall, a filter cartridge cup, and a filter cartridge lid which fit together to hold a filter therebetween in a filter cartridge chamber. The filter is a hydrophobic, gas-permeable, particular matter filter that is disposed within and extends entirely across the filter cartridge chamber. Ambient air entering the hubcap through the hubcap breather assembly is filtered to exclude both particulate matter and water before entering the wheel bearing chamber. The filter is preferably formed of three layers, including an outboard porous layer of sintered polypropylene plastic, an intermediate hydrophobic layer of polytetrafluoroethylene, and an inboard porous layer of sintered polypropylene plastic. The filter can be replaced by separating the filter cartridge lid from the filter cartridge cup.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
