Abstract
A sealing bush for a moving part has a packing made up of two concentric layers which are bonded to one another. The outer layer consists of a material such as graphite having good resilience. The inner layer, on the other hand, consists of a material such as sealing cord having a coefficient of friction with the moving part which is lower than the coefficient of friction between the moving part and the outer layer. The outer layer bears against the inner layer.
Claims16
A sealing device for moving parts, particularly for use at high pressures and temperatures, comprising a packing having two layers, one of said layers surrounding the other of said layers and being more resilient than said other layer, and the coefficient of friction between said other layer and a moving part being lower than the coefficient of friction between said one layer and the moving part, said layers being pressed together so that said one layer resiliently bears upon said other layer.
