ABSTRACT:
A diverter valve arrangement for a fluid flow duct having selectively alternative outlets. In order to avoid an over-area condition during transition an additional valve is provided to delay the effect of operating the main changeover valve. The diverter valve comprises a sleeve valve which covers/uncovers side outlet ports in the duct wall and a blocker valve made up of a plurality of segments pivoted to the inside of the sleeve valve. As the sleeve translates to uncover the side ports the blocker valve leaves deploy to obstruct axial flow. The additional sleeve valve acts as a shuttle and temporarily follows the main sleeve to delay uncovering the side ports.
