摘要：A combination distributor purge valve unit for a turbine engine has a pilot airsection, a fuel section, a distributor section and a purge air section. A spool moves alonga spool axis to control flow through six sets of radially arranged removable fill nozzlesand fixed outlet orifices in the distributor section. The spool moves from its initial
position in which the distributor outlets are in communication with the inlet to the purgeair section and closed off from the inlet to the fuel section so that high temperaturepurge air can forced passed the downstream side of the spool and into the nozzles in thecombustion can of the turbine engine to eliminate coking in these areas. The spool movesagainst a biasing spring under the force of a pilot air driven actuator piston and the forceof the pressurized fuel so that fuel can flow, initially through the fill nozzles and then theoutlet orifices, to the combustion can.
