ABSTRACT:
An isolation seat assembly for a fuel injector that is at least partially disposed within a stepped bore defined by a cylinder head, the stepped bore includes a land. The isolation seat assembly includes a cupped spring washer and an elastomeric ring member disposed between the cupped spring washer and the land. The isolation seat assembly operates to bias the fuel injector away from the land to substantially isolate the fuel injector from the head. The cupped spring washer and elastomeric ring member may be bonded to one another. Additionally, the isolation seat assembly may include a washer member between the elastomeric ring member and the land. The washer member operates to distribute axial forces from the fuel injector to the land. At least a portion of the washer member may be crimped into engagement with the cupped spring washer, thereby capturing the elastomeric ring member therein between.
