ABSTRACT:
A one-way flap-type vehicle ventilation valve comprises a generally planar molded plastic sealing flap for overlying a flow opening formed through a vehicle body panel. The flap is formed in a two shot molding process to have a rigid plastic main body with a resilient plastic seal lip about its periphery. A plastic support shaft is molded integrally with the main body and is spaced therefrom by integral support webs. A plastic support is pivotally joined to the support shaft by connecting portions of the bracket that are molded about the ends of the support shaft. Fasteners extend from the bracket for joining the valve to the vehicle body panel. The fasteners include end portions for passing through holes formed through the vehicle body panel adjacent the flow opening.
