Variable center pivot tumble control valve geometry for an intake manifold
A tumble control valve (10) for an intake manifold (12) of an engine which eliminates or substantially reduces air leakage between the bottom (28b) and sides (28c) of the valve blade (28) through a selected rotational segment (50) of the blade (28) as it moves from the closed position (FC) toward th...

| description | A tumble control valve (10) for an intake manifold (12) of an engine which eliminates or substantially reduces air leakage between the bottom (28b) and sides (28c) of the valve blade (28) through a selected rotational segment (50) of the blade (28) as it moves from the closed position (FC) toward the open position (FO). The sealed area (SA) is maintained by contouring the inner cavity (26) wall to track the arc defined by the bottom edge (28b) of the rotating blade (28). In other embodiments, a flexible flange (30) or wedge-shaped element (34) is attached to the blade to engage the inner cavity wall (28b) through the selected rotational segment (50). In another aspect of the invention, air flow pressure is maintained and tumble is optimized compared to rotational movement of the blade by contouring the top wall surface (24a) to track the arc defined by the rotating upper edge (28a) of the blade (28). |
