| Zusammenfassung: | An adhesive layered backflow preventer laminate, for use in impeding airflow from flowing in a backflow direction through the backflow preventer and a corresponding cooling fan, includes a thin front support layer adhered to a thin backflow flap layer, having a plurality of backflow flaps, which is adhered to a thin rear support layer. Each of the structural layers is adhered to the adjacent structural layer using a respective double-sided adhesive layer, by way of a manufacturing process that avoids the use of costly injection molded parts and machined plastic parts and metal components such as springs and hinges. |
