BRENNSTOFFVERTEILERVENTIL FÜR EINE GASTURBINE

摘要

A fuel delivery system (10) incorporates a fuel splitter valve assembly (30) including a first valve (40) having a selectively positionable spool (42) disposed therein for controllably metering fuel flow therethrough for delivery to a first combustion chamber (22) and a second valve (50) operative to pass a second portion of the fuel flow to a second combustion chamber (24) while maintaining at least a desired minimum pressure upstream of the first valve (40) whenever the second combustion chamber is in operation, and to shut-off fuel flow to the second combustion chamber whenever the second combustion chamber is not in operation.
