The seal assembly comprises a seal ring having an annular lip adapted to be brought into sealing sliding engagement with the inner side surface of the casing, a bellows type spring connected at one end with the seal ring and an annular member connected to the other end of the spring and seated in the seal groove. An auxiliary seal is positioned between the annular member and the wall of the seal groove.
