ABSTRACT:
A fluidic valve which includes a supply nozzle for discharging a fluid po stream, and a pair of outlet channels for receiving the power stream. A rigid member is disposed inside the power nozzle so that it splits the power stream evenly and fluid exits via the two outlet channels with equal pressures. A shaft upon which the rigid member is mounted is responsive to an external input signal for causing the rigid member to turn so that fluid exits via the two outlet channels with a proportional pressure differential output signal being produced across the outlet channels. A centering spring returns the rigid member to its null position when no external input signal is applied to the shaft.
