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.
L'invention concerne un injecteur de carburant. L'injecteur de carburant comprend un support d'injecteur et un blindage thermique couplé au support d'injecteur. Le blindage thermique interagit uniquement avec le support d'injecteur par l'intermédiaire de contacts tel que des contacts ponctuels, des contacts linéaires ou des contacts superficiels. En outre, le blindage thermique comprend une partie corps, une partie extrémité radialement évasée et un épaulement dirigé radialement, interposé entre la partie corps et la partie extrémité évasée. La partie épaulement agit en tant que point de flexion qui fléchit et absorbe l'expansion thermique du blindage thermique.
