Title:
SELF-ALIGNING SEALING APPARATUS PROVIDING AXIAL SEALING AND CONTROLLED COMPRESSION LIMITS
Document Type and Number:
WIPO Patent Application WO2003081092
Kind Code:
A3
Abstract:
A sealing apparatus (10) includes an annular seal (12) and a retention ring (14) annularly disposed about and joined to the seal. The retention ring (14) fully supports, retains and carries the seal so that the application environment need not provide any structure to hold the seal, such as a machined groove. The seal is disposed in axial seal engagement with two cylindrical tubes that are registered in fluid communication with one another (6, 8). A means (32) is provided to limit axial compression of the seal so as to prevent seal extrusion otherwise arising from excessive compression.
