Abstract
The mechanical seal comprises a seat ring and a sealing ring or flange, with sealing faces, acting between an inner fluid outside the ring and an outer one inside it. There is an auxiliary seal between the sealing ring and a guide member, on or through which the ring moves in the axial direction. The peripheral surfaces, radially opposite and spaced apart, of the ring (4) and the guide member (6) are stepped so as to form an annular space between them. The auxiliary seal (9) fits in this space, being compressed and movable in the axial direction. It divides the space into pressurised inner (13) and outer (12) working chambers for the inner and outer fluids.
