Abstract

La présente invention concerne un dispositif de charge (1), en particulier un turbocompresseur, muni d'un dispositif de commande (2) pour actionner un dispositif de réglage (3), en particulier d'une géométrie de turbine variable ou d'une soupape de décharge, le dispositif de commande (2) étant couplé via une bielle de commande (4) au dispositif de réglage (3). Selon l'invention, la bielle de commande (4) est couplée via une pièce de guidage (6) logée, de manière à pouvoir tourner, en deux endroits dans un levier d'actionneur (5) au dispositif de réglage (3). On peut ainsi obtenir un ajustement simple et une aptitude au réglage aisée et à long terme.
