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 délivré par un accumulateur de pression (33), un premier circuit fluidique (31A, 32A) reliant la chambre supérieure à l'accumulateur et comprenant un premier ensemble de vanne (2A), un deuxième circuit fluidique (31B, 32B) reliant la chambre inférieure à l'accumulateur (33) et comprenant un deuxième ensemble de vanne (2B), caractérisé en ce que le premier et/ou le deuxième circuit(s) fluidique(s) au moins comporte une ouverture de fuite calibrée du fluide, le premier et/ou le deuxième circuit(s) fluidique(s) comportant en outre un conduit de dérivation (50) comprenant un clapet anti-retour (51) et arrangé pour raccorder l'une des chambres à l'accumulateur, ledit conduit de dérivation.The invention relates to a device for controlling the compression ratio of a variable volumetric ratio engine, comprising a control cylinder comprising a piston (111) delimiting two chambers (112, 113) intended to receive a pressurized fluid delivered by a pressure accumulator (33), a first fluid circuit (31A, 32A) connecting the upper chamber to the accumulator and comprising a first valve assembly (2A), a second fluid circuit (31B, 32B) connecting the lower chamber to the accumulator (33) and comprising a second valve assembly (2B), characterized in that the first and / or the second fluidic circuit (s) at least comprises a calibrated leakage opening of the fluid, the first and / or or the second fluidic circuit (s) further comprising a bypass duct (50) comprising a nonreturn valve (51) and arranged to connect one of the chambers to the accumulator, said bypass duct.
