| 摘要 |
A seal system for a spherical joint in which the metal seal ring is sandwiched coaxially between two wedge-shaped metal compression rings which are inserted into corresponding cavities in the front surfaces of the seal ring and are pressed against a metal stop ring by a series of flat springs which become preloaded as a result of forcing the female part of the joint onto the male part. |
