Publication number: 20170370484Abstract: 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.Type: ApplicationFiled: June 26, 2017Publication date: December 28, 2017Applicant: NABTESCO CORPORATIONInventors: Keitaroh OHSHIO, Yu SHIBATA, Satoshi ASADA
