ABSTRACT:
A fuel injector is provided. The fuel injector includes an injector support and a heat shield coupled to the injector support. The heat shield only interacts with the injector support by way of contacts such as point contacts, line contacts or surface contacts. Further, the heat shield includes a body portion, a radially extending flared end portion and a radially directed shoulder interposed between the body portion and the flared end portion. The shoulder portion acts as a flexure point that flexes and absorbs thermal expansion of the heat shield.
