Title (EN) METHOD FOR ACHIEVING FINAL AIR GAP AND PARALLELISM OF A FUEL INJECTOR CONTROL VALVE
(FR) PROCÉDÉ PERMETTANT D'OBTENIR UN ENTREFER FINAL ET UN PARALLÉLISME D'UNE SOUPAPE DE COMMANDE D'INJECTEUR DE CARBURANT
Abstract:
(EN) A method for achieving final air gap and parallelism of a control valve (12) of a fuel injector (10), said control valve (12) having a body (14) defining an transverse top face (18) and comprising a thick disc magnetic armature (28) having a planar transverse upper face (30). The method comprising the steps: a) measuring the actual position from the armature upper face and the body top face and, determining the actual parallelism error between said faces; b) ablating the armature to generate an ablated upper face parallel to the body top face (18), the distance from the ablated upper face to the body top face being a final air gap.
(FR) L'invention porte sur un procédé permettant d'obtenir un entrefer final et un parallélisme d'une soupape de commande (12) d'un injecteur de carburant (10), ladite soupape de commande (12) ayant un corps (14) délimitant une face supérieure (18) transversale et comprenant une armature magnétique à disque épais (28) ayant une face supérieure transversale plane (30). Le procédé consiste : a) à mesurer la position réelle à partir de la face supérieure d'armature et de la face supérieure de corps et, à déterminer l'erreur de parallélisme réelle entre lesdites faces; b) à effectuer une ablation de l'armature pour générer une face supérieure ayant subi une ablation parallèle à la face supérieure (18) du corps, la distance de la face supérieure ayant subi l'ablation à la face supérieure du corps étant un entrefer final.
