Gas Turbine Fuel Metering Unit
US Patent:
8127524, Mar 6, 2012
Filed:
Jan 10, 2007
Appl. No.:
11/621685
Inventors:
Charles H. Falke - Union CT, US
Leo J. Veilleux - Wethersfield CT, US
Douglas A. Parsons - Canton CT, US

Assignee:
Hamilton Sundstrand Corporation - Windsor Locks CT
International Classification:
F02G 3/00
US Classification:
60 39091, 417308
Abstract:
A fuel system for a turbine engine is provided. The fuel system includes a positive displacement pump driven by an electric motor. The pump is rotated in a first direction to deliver fuel to the turbine engine, and a second direction for evacuating fuel from the turbine engine. A shut-off check valve is open in a first direction in response to a first differential pressure created by the pump in the first direction. The shut-off check valve is biased to a closed position when the pump is rotating in the second direction. An ecology check valve is biased to a closed position in the first direction and open in the second direction in response to a second differential pressure created by the pump. The check valves open and close automatically in response to the pressures generated by the positive displacement pump in each of the first and second rotational directions. In this manner, simple, reliable valves are utilized to regulate the flow of fuel in the fuel system.
