Claim Text:
1. A device for preserving fluid systems of a turbine engine, the turbine engine including engine shafts, the fluid systems including a fuel system and an oil system, the fuel system having a fuel therein and a fuel pump for conveying the fuel or an oil therein, and the oil system having the oil therein and an oil pump for conveying the oil therein, the device comprising: at least one drive operatively connected to each of the fuel pump and the oil pump for driving the fuel pump and the oil pump; a first valve assembly operatively connected between the fuel system and the oil system and switchable between at least a first setting and a second setting; a second valve assembly having a first inlet fluidly connected to a first location on the fuel system downstream of the fuel pump and a first outlet fluidly connected to a second location on the fuel system upstream of the fuel pump and switchable between at least a first setting and a second setting; wherein, when switched to the second setting, the second valve assembly interrupts fluid communication between the first inlet and the first outlet such that the fluid in the fuel system cannot circulate therethrough; a fuel tank line fluidly connectable at a first location to a fuel tank and fluidly connected at a second location to a second outlet on the second valve assembly and providing fluid communications between the first and second locations; wherein the second valve assembly is further switchable to a third setting;
