<p>Sliding seal constructions including resilient support members carried by a base member in conjunction with a layer of low coefficient friction material extending over the support member at least within a sliding zone of the seal. This layer is connected at respective opposite sides of the support member so that engagement of the seal with a counter surface moving in respective opposite directions does not result in removal of the layer from the sliding zone. Preferred embodiments include arrangements for sealing a rotating shaft, support members with a plurality of lobes for backing the layer in a plurality of positions, unitary base and support member constructions, constructions with separate base members and support members interconnected with one another by dovetail connections, as well as constructions where the layer encapsulates the support member.</p> |
