Servo-valve and fluidic device

A servo-valve that drives an actuator by using a fluid, the servo-valve comprising:

• a nozzle that includes a discharge edge forming an outline of a discharge port from which the fluid is discharged and a tapered inner wall growing narrower toward the discharge edge;
• a receiver that includes an inflow surface provided with a first inflow port into which a part of the fluid discharged from the discharge port flows and a second inflow port into which the rest of the fluid discharged from the discharge port flows;
• and
• a driving unit structured to rotate the nozzle around a rotation axis and from alignment lines on which the center lines of the first inflow port and the second inflow port are aligned,
• wherein the driving unit drives the nozzle to displace the nozzle from a neutral position in which an extended line extended in the fluid discharge direction from a center of the discharge port intersects the alignment lines of the first inflow port and the second inflow port,
• wherein the tapered inner wall and a virtual plane enclosing the extended line and the alignment lines form a first straight line of intersection and a second straight line of intersection, and
• wherein when the nozzle is positioned at the neutral position, a first extended line of the first line of intersection extends inside the first inflow port and a second extended line of the second line of intersection extends inside the second inflow port.
