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 characterisitics 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 discharge port for discharging fuel flow into the fuel receiving chamber as metered by the valve member in dependence on the pressure of fuel. The valve seat member is adjustably received on the injector tip and preferably includes a deflectable portion accessible externally of the injector tip for facilitating adjustment of the valve cracking pressure.
