摘要： A sealing assembly with a first molded graphite ring of generally triangular cross section, one side of which is in use perpendicular to the longitudinal axis of a rotatable and/or slidable shaft, the surface of which is to be sealed in an axial direction against fluid leakage therealong, and a second side which is in use disposed parallel to said shaft to engage the inner wall of the housing surrounding said shaft. The invention further comprises a second molded graphite ring of generally triangular cross section and of generally similar dimensions to the first molded ring, with the second ring being in use installed in inverted relationship to the first ring to define there between an axially extending void around said shaft together with a third molded graphite ring having a triangular cross section and installed between said and first and second rings to substantially completely fill said void prior to the application of axial pressure to said rings to develop a sealing force between the inner wall of said housing and said shaft. The combination relates to fluid sealing and is in particular concerned with sealing against leakage along rotating or rotatable shafts, or reciprocating and/or reciprocable shafts.
