Abstract (en)
[origin: EP2626524A1] A valve stem seal assembly has a metal retainer, an elastomeric seal, and a metal valve guide. The metal retainer and the elastomeric seal are attached to each other, and the elastomeric seal is in sealable contact with the metal valve guide, while the metal retainer is in metal-to-metal gripping contact with the metal valve guide. A stop may be formed in the metal retainer that cooperates with a shoulder formed in the metal valve guide in order to prevent over-installation of the assembly of the elastomeric seal with attached metal retainer, when this assembly is installed over the metal valve guide.
