  • Asymmetrical intake damper valve
    Publication number: 20070034466
    Abstract: A valve assembly progressively opens to provide a smooth transition from a closed position to an open position. The fluid pressure reacts against a valve plate in a non-symmetrical manner to progressively open the valve. The valve can include a plurality of varying sized fluid passages or valve lands can be positioned eccentrically to each other to provide a non-symmetrical pressure area.
