Method and apparatus for piston-actuated elastomer probe seal in a hydraulic coupling member |
摘要 |
A female hydraulic coupling member has an elastomer probe seal molded to or abutting a ring-shaped metal base which is adapted to exert a compressive force on the probe seal when exposed to hydraulic fluid pressure. The compressive force causes the seal to expand in a radial direction thereby increasing its sealing effectiveness. A retainer nut for holding the seal in the receiving chamber may have a angled surface which acts to urge the seal in an inward, radial direction when an axial, compressive force is applied to the seal. |
