ABSTRACT:
An annular seal apparatus of the labyrinth type includes at least a pair of axially stacked thin diaphragm members. Each of diaphragm members includes a planar array of radially and circumferentially extending fingers separated by gaps. The pair of diaphragm members are disposed so that the fingers of each block the gaps of the other to define an axially extending annular labyrinth.
