发明名称 Wear-compensating sealing ring assembly
摘要 A seal assembly for a reciprocating piston system is provided that compensates for uneven wear rates between the ring components of the seal assembly by initially sizing a portion of the width of the sealing ring larger than the width of the annular recess in the cover ring, this portion at least partially overlapping the gap in the cover ring but not the gap in the sealing ring.

主权项 1. A seal assembly comprising: a sealing ring having a sealing ring gap formed therein, an inner sealing ring wall, an outer sealing ring wall, wherein the outer sealing ring wall opposes the inner sealing ring wall, a top sealing ring wall and a bottom sealing ring wall wherein the bottom sealing ring wall opposes the top sealing ring wall, the top sealing ring wall having a radial sealing ring width, wherein one of the inner sealing ring wall and the outer sealing ring wall is a sealing wall; and a cover ring having a cover ring gap formed therein, an inner cover ring wall, an outer cover ring wall, wherein the outer cover ring wall opposes the inner cover ring wall, a top cover ring wall, and a bottom cover ring wall wherein the bottom cover ring wall opposes the top cover ring wall, an annular recess having a floor that opposes the bottom cover ring wall and a recess wall that opposes one of the inner cover ring wall and the outer cover ring wall, the floor having a radial recess width and a sealing edge that is distal to the recess wall; wherein the sealing ring and the cover ring have an assembled position in which the sealing ring is seated in the annular recess of the cover ring, the sealing ring gap does not overlap the cover ring gap, wherein the sealing ring and the cover ring form a first region and a second region when in the assembled position, wherein the first region overlaps the sealing ring gap and not the cover ring gap and the second region overlaps the cover ring gap and not the sealing ring gap, wherein the radial recess width is equal to the radial sealing ring width in the first region, and wherein the radial recess width is less than the radial sealing ring width in the second region.
