Abstract (en)
[origin: WO2012013808A1] The invention relates to a driving stage for a two-stage servo valve, the driving stage being of the jet type, comprising an ejector (20) for ejecting a fluid jet and which is movable opposite a baffle (6) capable of generating a pressure differential that can be used to move a slide (3) of the servo valve. According to the invention, the ejector (20) radially projects from a column (21) to which the ejector (20) is rigidly connected, while being in fluid communication with a central opening (22) of the column through which fluid is supplied to the ejector, the column having a first end which is fitted onto the servo valve (23) and through which the fluid is fed into the column, and the column having a second end that is subjected to the load of a torque motor (26) for selectively twisting the column in one direction or the other about a starting position.
