Abstract:
A time multiplexed fluid control system for controlling the positions of multiple valve devices, each valve device having a control chamber, comprising:a fluid multiplexer having a plurality of positions for selectively connecting an input and a plurality of outputs, one of the outputs fluidically connected to the control chamber of each valve device;a modulating valve in fluid communication with the input, producing a controlled output flow through the input, the position of the fluid multiplexer determining which of the outputs receive the controlled output flow; anda pressure transducer in fluid communication with the fluid multiplexer and connectable to a plurality of channels thereby, the position of the fluid multiplexer determining which of the channels the pressure transducer is in communication with, the pressure transducer operable to produce a multiplexed feedback signal representative of sensed pressures in the channels.
