Abstract (en)
[origin: EP0301620A2] The electroinjector is equipped with a central magnetic core (10) from which a guide tube (19) protrudes, which acts as a guide for an anchor (12) of ferromagnetic material, which bears the injector shutter (17). In a form of practical embodiment, the anchor (12), in its opening movement, comes to stop against a shoulder element (24) made from an amagnetic material fastened on the core (10) in such a protruding position, as to define an air gap (T) and prevent the core (10) and the anchor (12) from magnetically sticking to each other. The shoulder element (24) is provided with a fastening cylindrical portion (30), and an adjacent portion (31) with a prevailingly radial development, which acts as the stop portion. The element, which can also be fastened onto the anchor (10), can be obtained from a rolled sheet or by drawing a thin tube.
