Abstract
A floating wiper seal assembly for sealingly engaging a reciprocating shaft within a hydraulic pump or cylinder housing. The seal assembly includes a generally cylindrical elastomeric seal body configured for reception within a cylindrical bore of the housing. An axial bore extends through the seal body for receiving the reciprocating shaft. A pair of opposed flexible annular lips extend radially inwardly from an interior surface of the axial bore for wiping and sealingly engaging the reciprocating shaft, and at least two flexible annular rings extend radially outwardly from the seal body for sealingly engaging an interior surface of the cylindrical bore. The elastomeric seal body is dimensioned and configured to float freely within the cylindrical bore in both a radial and axial direction upon flexure of the annular lips and annular sealing rings in response to reciprocating movement of the shaft while maintaining sealing engagement with the shaft and the pump or cylinder housing, respectively.
