Abstract
A pressure vent valve for ventilation of the interior of a motor vehicle, with a frame with at least one sealing surface and with at least one flexible valve flap mounted on the frame. In an idle position, the valve flap assembly abuts the sealing surface to prevent airflow through the pressure vent valve. When a sufficient pressure occurs, the valve flap assembly assumes an open position lifted from the sealing surface to allow airflow through the pressure vent valve. The pressure vent valve further includes an installation indicator formed in or on the frame to ensure alignment during installation.
Claims20
A pressure vent valve for ventilation of an interior of a vehicle, the pressure vent valve comprising:
- a frame defining a vent opening;
- a valve flap mounted on the frame and configured to transition between an idle position where airflow through the vent opening is blocked and an open position where airflow through the vent opening is not blocked;
- and
- an installation indicator formed in or on the frame.
A return valve installation system for a vehicle component, the return valve installation system comprising:
- a pressure vent valve having a frame and a valve flap configured to block a vent opening formed in the frame;
- an installation indicator coupled to the pressure vent valve;
- and
- a reader separate from the pressure vent valve and operatively coupled to a computer, the reader configured, via a processor, to track the installation indicator during installation of the pressure vent valve into an aperture of the vehicle component.
