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 an arcuate valve member movable relative to a valve seat member having a fuel discharged port for discharging fuel flow into the fuel receiving chamber as metered by said valve member in dependence on the pressure of fuel. The valve member comprises an arcuate reed-type valve received in a generally cylindrical tubular valve seat insert with the flow area of the fuel discharge port adjustable externally of the valve seat insert for adjusting the valve cracking pressure.
