Enhanced pilot stage servovalve

A servovalve with jet-type pilot stage including an ejector for ejecting a jet of fluid and that is movable relative to a deflector adapted to generate a pressure differential that can be used to move a power distribution member of the servovalve, the ejector projecting radially from a column extending along a longitudinal axis and to which the ejector is fastened, the ejector being in fluid communication with a central passage of the column via which the ejector is fed with fluid, the column having a first end pivotably engaged in a part of the servovalve in the vicinity of a pressure feed thereof and via which the fluid is introduced into the central passage of the column, the column having a second end loaded by a torque motor to apply selectively to the column a rotation torque about the longitudinal axis in either direction relative to a rest position, the servovalve further comprising elastic means for returning the column to the rest position, the elastic means including a thin tube surrounding the column,

• wherein the entire column is pivotable with respect to the servovalve.
