Abstract
A labyrinth type seal assembly having one or more controlled porosity elements retained in the labyrinth pathway between relatively rotatable seal elements. Preferably the controlled porosity elements are formed of open celled foam material such as polyurethane. The controlled porosity elements assist in preventing the ingress of contaminating solid or liquid materials, the loss of sealed materials and the flooding or overloading of drain ports.
