ABSTRACT:
A hubcap attached to a wheel wherein a chamber is formed between the hubcap and the wheel for housing a lubricating fluid for the associated wheel bearings. A vent passage extending through the hubcap is provided for relieving the pressure formed in the chamber. A first one way valve is positioned to cover the vent passage for allowing a flow of gases to exit the vent passage while preventing liquids and other contaminants from entering the vent passage. A porous material is mounted across an air inlet passage extending through the hubcap for allowing air to enter the chamber. A second one way valve is mounted across the air inlet passage between the chamber and the porous material to shield the outer surface of the porous material from exposure to lubricating fluid from the chamber.
