Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
140 words
A fluidic flow diverter comprising: a substantially rigid body; a supply nozzle for discharging a fluid power stream formed in said body; a pair of outlet channels formed in said body for receiving the power stream a pinstably mounted tapered rigid control member disposed inside the power nozzle in a first position so that it splits the power stream evenly and fluid exists via the two outlet channels with equal pressures; a plurality of vents for exhausting fluid overspill from the outlet channels disposed between the supply nozzle and the outlet channels, and turning means responsive to an external input signal for causing the rigid control member to be displaced from said first position so that fluid exits via the two outlet channels with a pressure differential proportional to the displacement of said member being produced across the outlet channels.
Claim 2
Dependent Claim
140 words
A fluidic flow diverter comprising: a substantially rigid body; a supply nozzle for discharging a fluid power stream formed in said body; a pair of outlet channels formed in said body for receiving the power stream a pinstably mounted tapered rigid control member disposed inside the power nozzle in a first position so that it splits the power stream evenly and fluid exists via the two outlet channels with equal pressures; a plurality of vents for exhausting fluid overspill from the outlet channels disposed between the supply nozzle and the outlet channels, and turning means responsive to an external input signal for causing the rigid control member to be displaced from said first position so that fluid exits via the two outlet channels with a pressure differential proportional to the displacement of said member being produced across the outlet channels.
Claim 3
Dependent Claim
23 words
