Abstract

L'invention concerne un dispositif de réglage pour un dispositif de suralimentation, notamment un turbocompresseur à gaz d'échappement, qui comprend un élément d'actionnement pouvant pivoter autour d'un axe de pivotement (10) et un élément coulissant pouvant coulisser au moyen de l'élément d'actionnement le long d'un axe de coulissement (12). L'élément d'actionnement et l'élément coulissant sont en liaison fonctionnelle l'un avec l'autre par le biais d'au moins un contour d'engagement (14) associé à l'élément d'actionnement et s'engageant dans un logement associé à l'élément coulissant. Un mouvement de rotation de l'élément d'actionnement peut être converti en un mouvement de translation de l'élément coulissant, et le contour d'engagement (14), par rapport à un système de coordonnées cartésien bidimensionnel (20), dont l'origine se situe sur l'axe de pivotement (10) et dont l'axe x correspond à un angle de pivotement α de l'élément d'actionnement et s'étend perpendiculairement à l'axe de coulissement (12) lorsque α = 0°, satisfait au moins en partie au moins sensiblement à l'allure suivante : formule (I) et formule (II).
