Abstract:
A labyrinth seal including a stator and a non-contacting rotor, and annular elastomeric seals. The confronting surfaces of the stator and rotor define at least one interface passage, including a radially-outermost annular interface passage between an annular, outermost, radially-extending projection of the stator and an annular rearwardly-extending distal projection of the rotor that overlaps the radially-extending projection of the stator, the radially-outermost annular interface passage tapering outwardly and rearwardly at an acute angle relative to an axial reference line. The annular elastomeric seals are stationary with the stator during dynamic operation of the rotor, and are not contacted by a surface of the rotor during dynamic operation. The interface can also have two radially-disposed exclusion chambers, the outer exclusion chamber being defined in part by a radially-inboard projection of the rotor. The stator can have a projection providing a contact avoidance interface position inboard of at least two contaminant-excluding interfaces.

Claim (Index 20):
The labyrinth seal of  claim 19 , wherein the inner annular surface of the intermediate annular projection of the rotor and the outer surface of the projection of the stator extend substantially parallel to an axial reference line.
