Abstract
A seal assembly for a rotatable shaft extending through a bore in a housing, particularly for high-speed applications such as turbo-charger rotors. An annular groove is provided around the shaft, and a first resilient split-ring sealing member is located in the groove. At least one second resilient split-ring sealing member is fitted over said first member, so as resiliently to bear on the wall of the housing defining the bore. Said first member is an axial close running fit within the groove, but of a lesser radial dimension than the depth of groove, whereas the axial width of said second member is smaller than that of said first member.
