ABSTRACT:
A mechanical seal assembly is provided for inhibiting a fluid located in a higher pressure region of an apparatus from flowing to a relatively lower pressure region. The seal assembly is configured for cooperation with a seal ring connected to a cylindrical shaft which rotates about its longitudinal axis and which is mounted in the apparatus housing. The seal assembly includes an outer casing in which is mounted a non-rotatable seal ring which encircles the shaft for limited axial movement toward and away from the shaft seal ring. A biassing element is mounted in the outer casing for urging the non-rotatable seal ring axially into slidably mating engagement with the sealing face of the rotatable shaft seal ring. The biassing element includes a cylindrical bellows which encircles the shaft and a spring. The bellows includes a collapsible outer wall with a first skirt on one end of the outer wall and a second skirt on the other end of the outer wall. The first skirt is bonded to the seal ring, and the second skirt is clamped axially against the outer casing end wall.
