ABSTRACT:
A unique fuel system for supplying fuel from a fuel source and to a turbine engine is disclosed and comprises a fuel inlet conduit having one end adapted for connection with the fuel source and a fuel outlet conduit having one end adapted for connection with the turbine engine. The other end of the inlet and outlet conduits are connected to a valve movable between a bypass and operating condition. Both ends of a third conduit are also connected to the valve while a fuel pump is fluidly connected in series with and at a midpoint of a third conduit. In its bypass position, the valve fluidly connects the inlet and outlet conduits together while simultaneously sealingly closing the third conduit and entrapping any fuel contained therein. In its operating condition, the valve simultaneously connects the inlet conduits with one end of the third conduit and the other end of the third conduit to the outlet conduits thus supplying fuel to the engine.
