Abstract

L’invention concerne une bielle télescopique de commande (30) pour un moteur à taux de compression variable comprenant : - un pied de bielle (30a) présentant respectivement un œilleton et un piston (34) à ses extrémités ; - une tête de bielle (30b) servant de corps de vérin dans lequel ledit piston (34) définit une première (31) et une deuxième (32) chambres hydrauliques, et une troisième chambre (33) latérale située entre la première (31) et la deuxième (32) chambres ; la tête de bielle (30b) comprend deux paliers latéraux (35) coaxiaux destinés à établir une liaison pivot avec une partie fixe du moteur ; - un circuit de lubrification (36) comprenant au moins un premier conduit (36a) aménagé dans la tête de bielle (30b), reliant un espace interne de chaque palier latéral (35) et la troisième chambre (33), quelle que soit la longueur de la bielle, et comprenant au moins un deuxième conduit (36b) aménagé dans le pied de bielle (30a), reliant la troisième chambre (33) et l’œilleton.
