Claims7
A two-stage hydraulic servovalve comprising:
- a power stage including a movable power distribution member;
- and
- a pilot stage comprising a torque motor having a rotor connected to a hydraulic fluid emitter or deflector, and a deformable feedback member operationally connected to the rotor and to the movable power distribution member in order to establish a mechanical connection between them,
- the servovalve being characterized in that the movable power distribution member has clamp means for clamping the feedback member, which means are arranged to allow a clamped portion of the feedback member to move relative to the movable power distribution member at least along a direction extending transversely to a clamping force generated by the clamp means.
