专利名称：Current-to-pressure transducer with enhanced performance features

摘要：An electric coil (20) induces a magnetic flux through a magnetic flow path (22, 24) which terminates in pole faces (26, 28) disposed parallel to a gap (30) therebetween. non-ferrous pivot element (36) is mounted to one of the pole faces adjacent an edge thereof most distant from the gap. An armature (40) which is at least partially ferromagnetic is held in firm frictional engagement with the pivot element by a taut band (42). The armature pivots about the pivot element in accordance with current flowing through the coil. A fluid nozzle (54) is mounted adjacent the armature such that fluid flow through the nozzle is throttled in accordance with pivotal movement of the armature, hence, the electrical control signal current in the coil.
