Abstract
A segmented labyrinth seal assembly and method according to which a plurality of arcuate segments extend around a rotating shaft with the shaft being engaged by a sealing portion of each segment, thus sealing against the movement of fluid in an axial direction along the shaft. An engagement member extends from one end of at least one segment and is adapted to engage the corresponding end of the adjacent segment. The engagement member is urged in a direction towards the corresponding end to apply a separation force between the ends, and the separation force is adjustable.
