In a variable geometry turbocharger, with a turbine housing having a standard inlet for exhaust gas and an outlet to the exhaust system of the engine, a volute connected to the inlet and an integral outer nozzle, a plurality of vanes having rotation posts extending from a first surface substantially parallel to the outer nozzle wall to provide the variable nozzle; the posts received in circumferentially spaced apertures in the outer nozzle wall; the vanes having actuation tabs extending from the opposite surfaces of the vanes; a unison ring engaged between the centre housing and the vanes and having a plurality of profiled slots equal in number to the vanes; the slots oriented obliquely to a circumference of the unison ring and receive the tabs; the profiled surfaces of the slots engage the substantially flat sides of the tabs on different surfaces during the translation to provide optimum control and wear reduction; a radial slot with crank shaft having a pin engaging the radial slot to actuate the unison ring, the crank shaft moveable continuously from a first position to a second position to cause the pin to translate in the radial slot; an integral hydraulic actuator providing the actuation mechanism for the crank shaft.
L'invention concerne un turbocompresseur à géométrie variable, utilisant plusieurs ailettes (36) placées dans une entrée de turbine dotée d'un anneau de conjugaison (48), et une paroi coulée d'une seule pièce dans le logement de turbine formant des parois de buse. L'anneau de conjugaison comprend des fentes d'actionnement (46) qui reçoivent des languettes (44) disposées sur les ailettes (36), de façon à ouvrir la zone de buse lors de la rotation dudit anneau de conjugaison (48). Un actionneur électrohydraulique d'une seule pièce fait tourner l'anneau de conjugaison (48) entraîné par un arbre manivelle à crémaillère, avec rétroaction de position directe vers le solénoïde à courant variable sous charge de ressort via une came sur l'arbre manivelle.
