Beschreibung
Zusammenfassung:	A system for controlling lubricant flow to a component in a gas turbine engine includes a control valve (172), an electromechanical actuator (174), and an engine controller (112). The control valve includes a lubricant inlet that is in fluid communication with a pressurized lubricant source, a lubricant outlet is in fluid communication with the gas turbine engine component, and a valve element that is movable to a plurality of valve positions. The electromechanical valve actuator is coupled to the valve element and is responsive to actuator commands to position the valve element. The engine controller is coupled to receive a pressure sensor signal indicative of a compressor pressure in the gas turbine engine and, in response, determines a commanded valve element position and supplies the actuator commands to the electromechanical valve actuator that cause the electromechanical valve actuator to move the valve element to the commanded valve element position.
