Abstract

L'invention concerne un dispositif pour piloter le taux de compression d'un moteur à rapport volumétrique variable, comprenant un vérin de commande comprenant un piston (111) délimitant deux chambres (112, 113) destinées à recevoir un fluide sous pression, un accumulateur de pression (33) délivrant le fluide sous pression, un premier circuit fluidique (31A, 32A) reliant la chambre supérieure (113) à l'accumulateur et comprenant un premier ensemble de vanne (2A) apte à commander l'écoulement du fluide dans ledit premier circuit fluidique, un deuxième circuit fluidique (31B, 32B) reliant la chambre inférieure (112) à l'accumulateur (33) et comprenant un deuxième ensemble de vanne (2B) apte à commander l'écoulement d'un fluide dans ledit deuxième circuit fluidique, caractérisé en ce que l'un des circuits fluidiques au moins comporte un conduit de dérivation (50) arrangé pour raccorder l'une des chambres (112, 113) à l'accumulateur (33), ledit conduit de dérivation comprenant un clapet anti-retour (51).
