Sealing ring e.g. X-ring, for sealing e.g. liquid medium, in piston pump i.e. ABS/ESP piston pump, of brake system, has reservoir filled with lubricant and arranged between two radial inner seal lips and two radially expressed seal lips

摘要

The ring (1) has a lubricant reservoir (7) filled with a lubricant (6) and arranged between two radial inner seal lips (2, 3) and two radially expressed seal lips (4, 5). A recess is provided in the lubricant reservoir. One of annular parts (8, 9) is in the radial inner seal lips and the radially expressed seal lips. Lubricant pockets (12) are formed in circular shape and arranged in the lubricant reservoir. An arc shaped curvature extends in axial direction of a D-Ring. A rectangle ring (23) is provided in an axial behind section. An independent claim is also included for a seal arrangement.
