This abstract first appeared for US patent application 18298965 titled 'Sealing Ring for Radially Engaging an Outer Surface of a Rotary Shaft

Simplified Explanation

The abstract describes a sealing ring designed to seal the outer surface of a cylindrical element, such as a rotary shaft.

  • The sealing ring has a ring base body with a central rotating axis.
  • It includes two sealing lips, a first lip and a second lip, that extend from the ring base body to seal the rotary shaft.
  • The sealing tips of both lips point in the same axial direction.
  • The first lip is positioned above the second lip in the axial direction, creating a distance between their sealing tips.


Original Abstract Submitted

A sealing ring for radially engaging an outer surface of cylindrical element, in particular a rotary shaft, is disclosed. The sealing ring includes a ring base body having a central rotating axis. The sealing ring further includes a first lip and a second lip that each extend from the ring base body to sealingly engage the rotary shaft. The sealing tips of both sealing lips point at least in part in the same axial direction. The first lip surpasses the second lip in axial direction such that the sealing tip of the first lip is arranged axially distanced to the second lip.
