ABSTRACT:
An airblast fuel injector tip is provided for reducing fuel vaporization problems as a result of high fuel temperatures without adversely affecting the airblast operational characteristics of the injector tip. The injector tip includes a fuel receiving chamber and a fuel discharge orifice downstream thereof and an arcuate, distensible, tubular valve member having a discharge end movable relative to a valve seat in the fuel receiving chamber in dependence on the pressure of fuel in the valve member to meter fuel to the fuel receiving chamber for discharge through the discharge orifice into a combustor.
