Abstract

L’invention concerne une bielle (10) de longueur variable comprenant : Une tête de bielle (102), destinée à établir une liaison pivot avec un maneton d’un vilebrequin, Un circuit hydraulique (104) de commande de la longueur de la bielle (10), Un système de pilotage (110) du circuit hydraulique. Le système de pilotage (110) comporte : Au moins un tiroir hydraulique (111) linéaire, agencé dans un logement de la tête de bielle (102), Au moins un premier patin (113) disposé sur un flanc de la tête de bielle (102), apte à subir une force d’appui exercée par un organe de pilotage, ladite force d’appui permettant de déplacer le tiroir (111), Un moyen de rappel, pour ramener le tiroir (111) dans sa position de repos, en l’absence de la force d’appui, Au moins un deuxième patin (115) disposé sur le flanc de la tête de bielle (102) et apte à subir la force d’appui. Figure à publier avec l’abrégé : F igure 1a
