Patent ID: 8525377

Claim:
A roto-linear actuator of the type comprising a sleeve and a clevis at one of the ends of said sleeve, said sleeve receiving the loads transmitted and/or received by the operating rod, wherein it comprises a sensor for measuring and controlling the micro-displacements which appear between two concentric regions of different diameters, one of which corresponds to said sleeve and the other to the inner extension of the anchoring lug of said clevis, said regions being connected by an axially deformable annular region which forms the shoulder of said clevis, said sensor comprising windings arranged in a field frame integrally attached to one of said concentric regions and a radially extending armature integrally attached to the other concentric region, said sensor additionally comprising measurement means for processing the signals issuing from said windings, said windings being torus-shaped in said field frame which is magnetically closed by said armature.
