Abstract
There is disclosed a seal assembly () for a machine such as a gas turbine engine. The seal assembly has a support structure () to which a resiliently deformable seal member () is mounted. A seal land () is opposingly spaced from the support structure () to define a gap therebetween, wherein the height of the seal member () in an undeformed condition is greater than the height () of the gap such that the seal member is deformingly pressed against the seal land () by the support structure to seal the gap therebetween in use. The support structure () and/or seal land () comprise an actuable member (), said member being actuable in a direction towards the other of the support structure and seal land to improve the resistance of the seal assembly () to an adverse condition in use, such as a fire.
