ABSTRACT:
A ring seal between a housing and a rotatable shaft comprising a plurality of ring members generally concentric with the shaft. A first ring member is provided having an outer annular surface facing externally of the housing, an inner annular surface facing internally of the housing and an annular recess in the inner surface. A flange is provided in the first member, projecting radially inward into the annular recess, thus forming an annular channel in the first member. An opening is provided, opening from the lowest point in the channel of the first member to the outer surface. The first member is fixedly attachable to the housing so as to allow for free rotation of the shaft within the first member. A second ring member is positioned axially internal to the first member and is provided with an outer annular surface facing the inner surface of the first member and an inner annular surface facing internally of the housing. The second member is fixedly attachable to the shaft and is provided with a flange which extends into the recess of the first member. A seal is thus provided which traps contaminants in the channel of the first member, allowing them to flow back to the atmosphere through the opening in the first member, whether the shaft is rotating or in a static position.
