Abstract
The metering servovalve () comprises a valve body (), an open/close element () and an electromagnet (), and is housed in a casing () of the injector (). The electromagnet () actuates a mobile armature () for a travel defined by a polar surface () of the core () of the electromagnet (). This latter is fixed in the casing () by means of a threaded ring nut (), with the interposition of at least one deformable adjustment shim (). The ring nut () is screwed with a pre-set tightening torque on a thread () of the casing () so as to bring about an elastic deformation of the adjustment shim () and to prevent accidental unscrewing of the ring nut (). The adjustment shim () is constituted by a metal ring with a cross section having a shape chosen between L, C, S, Z, and Σ.
