Patent ID: 7290566

Claim:
A diverter valve for bulk solids comprising: a housing presenting an inlet and first, second, and third outlets; first gate structure moveable between a first position which blocks said first outlet and a second position wherein said first outlet is open; second gate structure moveable between a first position which blocks said second outlet and a second position wherein said second outlet is open, each of said first and second gate structures blocking said third outlet when the gate structure is in its second position, each of said gate structures comprising a rigid planar component having an edge which is spaced from said housing and a peripheral resilient component, said resilient component projecting from said edge of said planar component to present a wiping seal against said housing; a first seal bar mounted on said housing and extending substantially around said resilient component of said first gate structure when said first gate structure is in its first position, wherein said resilient component sealably engages said first seal bar when said first gate structure is in its first position; a second seal bar mounted on said housing and extending substantially around said resilient component of said second gate structure when said second gate structure is in its first position, wherein said resilient component sealably engages said second seal bar when said second gate structure is in its first position; and a pair of third seal bars on said housing for engagement by the resilient component of each of said gate structures when the latter is in its second position, wherein each of said third seal bars is discontinuous and presents an open space for receiving said resilient component when the latter is in sealing engagement with said third seal.
