Split mechanical face seal with seal face fluid introducing structure
First Claim
1. A split non-contacting mechanical face seal for providing fluid sealing between a housing and a rotating shaft, said seal comprisinga first seal ring having at least two split seal ring segments and a radially extending first seal face,a second seal ring having at least two split seal ring segments and a radially extending second seal face, said first and second seal faces being opposed to one another,one of said first seal ring and said second seal ring being connected to said rotating shaft to rotate therewith, the other of said first seal ring and said second seal ring being connected to said housing, andmeans for introducing a fluid to said first seal face and said second seal face and for producing a generally primarily hydrostatic force to maintain axial separation of at least a portion of said first seal face from at least a portion of said second seal face during operation, wherein said means for introducing includes a fluid conduit formed in one of said first and second seal rings.

Abstract
A split face seal that provides fluid sealing between a housing and a rotating shaft includes first and second seal rings each having at least two seal ring segments and a radially extending seal face. The seal ring faces of the seal rings are opposed to one another. One of the seal rings is connected to the rotating shaft to rotate therewith, while the other seal ring is connected to the housing. The split seal also includes a mechanism for introducing a fluid to the seal faces of the first and second seal rings and a split support member having at least two support segments for radially supporting the first seal ring to inhibit radial separation of the seal ring segments of the first seal ring.
