Abstract
A method and means are described for rapidly evacuating trapped air from the top of a top-loaded liquid filter housing. An air vent means is provided that prevents complete sealing between a bypass valve and a sealing surface on an endcap of a replaceable filter element. The air vent means enables the rapid evacuation of trapped air in the top of the housing chamber, but permits only a negligible flow rate of liquid, for example oil, through the air vent means once air is evacuated due to high viscosity ratio of liquid, such as oil, versus air.
