Abstract
A fuel split control arrangement is provided. The arrangement includes a staged cooling flow control valve and cooling check valve. The staged cooling flow control valve and cooling check valve is connected between the primary and secondary tips of a nozzle in a turbine engine. The staged cooling flow control valve and cooling check valve includes a valve member arrangement operable to prevent fuel flow from the secondary fuel supply manifold to the secondary tip and simultaneously allow fuel flow from the secondary fuel supply manifold to the primary tip such that the primary tip receives fuel flow from both the secondary fuel supply manifold and the primary fuel supply manifold.
