The invention relates to an oil pump driven by a hydraulic motor, that is itself driven by fuel pumped by a remote fuel pump through the engine fuel line. The hydraulic fuel driven oil pump is particularly advantageous for use in a gas turbine engine, to reduce dependence on or completely eliminate the auxiliary gear box (AGB) conventionally used to mechanically connect various engine systems with an engine shaft. Separating the oil pump and other fuel/oil system components from the AGB enables the rationalization of these systems and allows designers to...
[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.]1. A fuel and oil system for a gas turbine engine comprising:a fuel circuit including a fuel pump, and a fuel line communicating between a fuel source and an engine combustor;an oil circuit including an oil pump comprising a hydraulic motor in communication with the fuel line and hydraulically driven by the motion of fuel supplied by the fuel line.
