    - la force de serrage axiale du dispositif de serrage (50) distinct de la soupape d'injection et la force d'appui radiale avec la valeur (F_RAD) sont appliquées sur le corps d'injecteur (14) et/ou sur le carter (16) de l'élément de commande, et
    - on fait varier la force de serrage axiale de l'élément de serrage (18) sur le corps d'injecteur (14) ou le carter (16) de l'élément de commande jusqu'à ce que la valeur (VAL_EL) de la grandeur électrique représentative de la course à vide (D) de la commande d'actionnement (22) se trouve dans la gamme de valeurs prédéfinie.
  6. Dispositif pour régler une course à vide (D) d'une commande d'actionnement (22) d'une soupape d'injection, concernant un élément de commande (26) pouvant être actionné par la commande d'actionnement (22), la commande d'actionnement (22) étant disposée dans un corps d'injecteur (14) et l'élément de commande (26) étant disposé dans la direction d'un axe longitudinal (A) en pouvant se déplacer dans un carter (16) de l'élément de commande, et le corps d'injecteur (14) et le carter (16) de l'élément de commande étant disposé axialement l'un par rapport à l'autre,
    le dispositif étant configuré pour
    - appliquer une force de serrage axiale sur le corps d'injecteur (14) et le carter (16) de l'élément de commande de telle sorte qu'une partie du corps d'injecteur (14) ou une partie du carter (16) de l'élément de commande, qui est disposée, dans un trajet de flux de force constitué par la force de serrage axiale, dans le corps d'injecteur (14) et le carter (16) de l'élément de commande, subisse une déformation permanente, jusqu'à ce qu'une valeur (VAL_EL) d'une grandeur électrique représentative de la course à vide (D) de la commande d'actionnement (22), déterminée directement ou indirectement, se trouve dans une gamme de valeurs prédéfinie,
    - appliquer au moins partiellement la force de serrage axiale sur le corps d'injecteur (14) et le carter (16) de l'élément de commande à l'aide d'un dispositif de serrage (50) configuré séparément de la soupape d'injection,
    - à l'aide du dispositif de serrage (50) distinct de la soupape d'injection, appliquer une force de serrage axiale, avec une première valeur prédéfinie (F_1), sur le corps d'injecteur (14) et le carter (16) de l'élément de commande,
    - à l'aide d'un élément de serrage (18) de la soupape d'injection, appliquer une autre force de serrage axiale, avec une valeur prédéfinie (F_SE), sur le corps d'injecteur (14) et le carter (16) de l'élément de commande,
    - déterminer une valeur de base (VAL_EL_BAS) de la grandeur électrique représentative de la course à vide (D) de la commande d'actionnement (22),
    - déterminer une deuxième valeur (F_2), dépendant de la valeur de base déterminée (VAL_EL_BAS) de la force de serrage axiale du dispositif de serrage (50),
    - appliquer la force de serrage axiale du dispositif de serrage (50), avec la deuxième valeur déterminée (F_2), sur le corps d'injecteur (14) et le carter (16) de l'élément de commande, et
    - faire varier la force de serrage de l'élément de serrage (18) sur le corps d'injecteur (14) et le carter (16) de l'élément de commande jusqu'à ce que la valeur (VAL_EL) de la grandeur électrique représentative de la course à vide (D) de la commande d'actionnement (22) se trouve dans la gamme de valeurs prédéfinie.
