Abstract

The present disclosure provides a servo valve assembly (100) comprising a first nozzle (114a) opposing a second nozzle (114b) and a shaft (120) positioned in the gap between the first and second nozzles (114a, 114b). The first and second nozzles (114a, 114b) are spaced apart by a gap and each nozzle (114a, 114b) has an outlet opening (116a, 116b). The shaft (120) defines a diameter (D) and a circumferential surface (121) and is rotatable about an axis of rotation (R-R). The shaft (120) defines first and second reduced radial portions (124a, 124b) around its circumferential surface (121), and the first and second reduced radial portions (124a, 124b) are in fluid communication with the first and second nozzle outlet openings (116a, 116b), respectively. The shaft (120) is configured to rotate between a first position where the first nozzle outlet opening (116a) is more occluded by the shaft circumferential surface (121) than the second nozzle outlet opening (116b), and a second position where the first nozzle outlet opening (116a) is less occluded by the shaft circumferential surface (121) than the second nozzle outlet opening (116b). A servo valve and method is also disclosed.
