Abstract
An injector seal assembly including a nozzle combustion shield is disclosed, the thermally conductive component of the injector seal assembly defining at least one groove to allow fluid communication between the main combustion chamber and a gap defined by a fuel injector and the injector seal assembly to facilitate the prevention of corrosion of the components.
Claims20
A method for assembly of an injector seal that is positionable around an exterior of a fuel injector, the method comprising:
- positioning a seal component around a longitudinally extending portion of a thermally conductive component, the thermally conductive component having a higher thermal conductivity than the seal component;
- and
- coupling the seal component with a head portion of the thermally conductive component that is located at an end of the longitudinally extending portion, the head portion including an end surface with at least one groove extending into the head portion.
A method for assembly of an injector seal that is positionable around an exterior of a fuel injector, the method comprising:
- positioning a ring-shaped seal component around a cylindrical thermally conductive component, the thermally conductive component having a higher thermal conductivity than the seal component;
- and
- press fitting the ring-shaped seal component into engagement with a head portion located at an end of the cylindrical thermally conductive component, the head portion including an end surface with at least one groove extending into the head portion.
