Patent ID: 7762477

Claim:
A method of sealing a fuel injector having a polymeric body extending from an inlet to an outlet along a longitudinal axis, the fuel injector having a seat secured to a polymeric support member, the method comprising: interposing an elastomeric member proximate an interface between an outer surface of the seat and an inner surface of the polymeric support member, and bonding the polymeric support member to the polymeric body proximate the outlet; wherein the interposing comprises insert molding a metallic seat with the elastomeric member to form the polymeric support member, wherein an annular pocket is provided on an outer surface of the metallic seat to retain the elastomeric member during insert molding, and wherein generally U-shaped fingers define the annular pocket thereby capturing a portion of the elastomeric member, with the insert molding of the polymeric support member capturing a remaining portion of the elastomeric member such that the elastomeric member is contacted by and completely surrounded by the combination of the metallic seat and polymeric support member.
