Abstract: The disclosure discloses a servo-valve that controls a fluid discharged from a discharge port of a nozzle by displacing the nozzle and drives an actuator. The servo-valve includes a receiver that includes an inflow surface provided with a first inflow port and a second inflow port into which the fluid discharged from the discharge port flows. The nozzle includes a force generation portion that includes an end surface provided with the discharge port and an outer circumferential surface formed in the periphery of the end surface. When the nozzle is displaced from a neutral position toward the first inflow port, the fluid inside the second inflow port is blown out toward the nozzle. The force generation portion collides with the fluid blown out from the second inflow port and causes an assisting force in a direction matching a nozzle displacement direction toward the first inflow port. The nozzle easily moves by the assisting force generated in the force generation portion and thus a response speed is improved.

Abstract: Servo-valve that controls fluid discharged from a nozzle discharge port by displacing the nozzle, and that drives an actuator. The servo-valve includes a receiver provided with a first inflow port into which the fluid discharged from the discharge port flows. At least either the discharge port or the inflow port is a non-circular opening formed such that the amount of change in the area of overlap of the discharge and inflow ports occurring when the nozzle is displaced from the initial position is larger than in cases where the discharge port and the inflow port are of circular form of the same area. The increased amount whereby the area of overlap between the discharge and inflow ports changes when the nozzle is displaced from the initial position lets the fluid flow into the inflow port more quickly, improving the response speed of the actuator.

Abstract: Servo-valve that drives an actuator by using a fluid. The servo-valve includes a nozzle having 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, and a receiver that is provided with a flow path into which the fluid discharged from the discharge port flows. The nozzle is displaced in a direction different from the fluid discharge direction. The flow path extension direction is inclined with respect to a direction orthogonal to an inflow surface facing the nozzle by an angle ?. A taper angle determined by the tapered inner wall is larger than twice the angle ?. With such a configuration, the component of flow force exerted from the fluid on the tapered inner wall decreases. Since the nozzle can be quickly displaced, response speed of the actuator is improved.
