Abstract

L'invention porte sur un moteur à rapport volumétrique piloté (100) comprenant un bloc moteur (10) comprenant au moins un palier (11), un vilebrequin (20), au moins une bielle (30) de longueur variable et au moins un élément de pilotage (40) porté par le vilebrequin (20) et apte à se déplacer en translation selon l'axe longitudinal pour coopérer avec un actionneur (31) d'un système d'ajustement de longueur de la bielle (30). Selon l'invention, l'élément de pilotage (40) comprend une première partie annulaire (41) coaxiale au tourillon (21) et susceptible d'être déplacée selon une première direction (Y1) parallèle à l'axe longitudinal par un organe actuateur (12) porté par le palier (11) et une deuxième partie annulaire (42) coaxiale au maneton (22), solidaire de la première partie (41) et susceptible d'établir un contact continu avec l'actionneur (31) du système d'ajustement de longueur de la bielle (30), lorsqu'elle est déplacée selon la première direction (Y1).
