ABSTRACT:
A multiplexed hydraulic control system includes a pressure transducer fluidically connected to the multiplexer for sequential or periodic connection to a plurality of channels. The multiplexed hydraulic control system provides hydraulic control flows to a plurality of second stage valves while simultaneously multiplexing the pressure transducer. The pressure transducer may be multiplexed to multiple second stage valves or actuators to provide multiplexed feedback for closed loop control of the second stage valves. The system may be used to split or throttle fuel flow to the nozzles of a combustion chamber in turbine engines.
