Abstract:

A shaft seal that is slidably mounted in a housing with essential equal or balanced forces acting on each radial side. Fluid from the high pressure side of the shaft is communicated to equal areas on the two sides by ducts and constrained to the design areas by O rings. The sea moves radially in response to shaft displacements while maintaining a sealing relationship between packing material and the shaft. Keywords Patents. SDW
