Abstract: A servovalve includes a torque motor section and a hydraulic section. The torque motor section may comprise first and second opposing pole pieces and first and second permanent magnets may be positioned between these first and second pole pieces. The torque motor section also comprises an armature/flapper assembly which comprises a torsion bridge, an armature plate and a flapper that is connected at a first end to the armature plate. The flapper extends from said armature plate along a first longitudinal axis X. The armature plate may extend between the first and second permanent magnets and along a second longitudinal axis Y that is perpendicular to the first axis X. The hydraulic section comprises: a housing that comprises a body section and a chimney section. The chimney section extends from the body section to a first end.
