Abstract
A system is disclosed for mounting the pre-vaporizing bowl to a wall of a turbine engine combustion chamber in such a manner that it is centered and in alignment with an opening, through the combustion chamber wall during assembly. Not only does the system provide for the centering of the pre-vaporizing bowl in the combustion chamber wall opening, but it also allows relative radial movement between these elements after the engine has been assembled. The system includes a support collar fixedly attached to the combustion chamber wall so as to extend around the generally circular opening in the upstream portion of the combustion chamber, as well as a locating flange fixedly attached to the pre-vaporizing bowl. A stud extending from the locating flange extends through a slot in the support collar such that only radial movement between the locating lfange and the support collar (and consequently between the pre-vaporizing bowl and the combustion chamber wall) is permitted. A resilient snap clip is interposed between the support collar and the locating flange.
