Overview
What is this invention?
Fuel filter cartridges with automated air-bleeding internal features
Do you have a clogged filter on your truck? Are you tired of replacing filters every time one goes bad?
The filter assembly includes a housing that has an outer cavity and an inner cavity. The gasket is disposed within the housing and forms a first seal with the central tube at the inner surface. The central tube extends into the inner cavity and includes an opening. A filter element is positioned within the housing and includes a filter media that can be used to filter a fluid. Additionally, there is an endcap with an annular tab portion that forms a second seal with the outer surface of the gasket when it's in its operating position within the housing. This allows air to flow from the inner cavity of house to opening in central tube located therein.

What are some similar inventions on the market?
There are a few similar products on the market that may be worth looking into. One option is the CUMMINS FILTRATION IP, INC. Filter Assembly which includes a housing with an outer cavity and inner cavity, and a gasket disposed within the housing. The gasket includes an inner surface, an outer surface, and a vent passage that circumvents both seals (the first seal made by the central tube extending into the inner cavity and the second seal created by the annular tab portion on the endcap when it is in its operating position). This allows air to flow from inside of the house out through this vent passage so that any particles or debris caught in between will be released easily. Another option is something like K&N's 77-9100 Air Intake System for Ford® F150™ vehicles which offers increased airflow to your engine via two large air filters mounted outside of your truck cab.
How could this be used?
A novel use for a filter assembly includes the assembly being used as a replacement airfilter in an engine. The filter assembly includes a housing having an outer cavity and an inner cavity, and a gasket disposed within the housing. The gasket includes an inner surface, an outer surface, and a vent passage. The gasket forms a first seal with a central tube at the inner surface. The central tube extends into the inner cavity and includes an opening. A filter element is positioned within the housing and includes a filter media configured to Filter fluid passing through it while also protecting against debris that may be drawn into or caught by the filtering media of the element. An endcap including annular tab portion seals tightly around one edge of each side of stackable filtration elements when they are inserted into openings in opposite corners of housings to create four stacked filters (two per corner). When installed in this manner, airflow is allowed freely through all four stacks unimpeded thereby providing superior air quality compared
What are some things to look out for with this?
There are a few potential risks to using this type of filter. One risk is that if the gasket fails, air could flow into the inner cavity of the housing and cause damage to the filter element or other components. Another risk is that if water leaks past the endcap, it could enter into the central tube and ruin the equipment.
What are the overall impressions of this invention?
The product seems to be of good quality and is likely to provide a considerable increase in air flow to the engine, which should result in an improvement in performance.
Here is a poem describing the invention
There once was a filter assembly
That included a housing and gasket
The gasket had a vent passage
And formed a first seal with the central tube
