摘要： A vent plug for a hub cap is provided. The vent plug includes a cover and base forming a chamber. A vent plug body extends from the base and forms a cavity. A shield is coupled to the vent plug body. The shield comprises an annularly extending disc that traverses the cavity. The shield includes a connecting surface to connect the shield to the vent plug body. The shield provides a lubrication/liquid barrier to inhibit lubrication (or other liquid) from entering the cavity formed by the vent plug body and the chamber. The connection between the shield and the vent plug body allows a gas (typically air) to vent past the shield into the cavity and, when pressure is sufficiently high, to the chamber and eventually atmosphere.
