Abstract
La présente invention se rapporte à un dispositif (10) de démarrage d'un moteur thermique (20) alimentant une pompe (30) dans un système hydraulique, ledit dispositif étant compris entre un accumulateur haute pression (41 ) et un accumulateur basse pression (42) et étant situé partiellement en parallèle de ladite pompe (30), ledit dispositif (10) étant caractérisé en ce qu'il comprend : • un clapet anti-retour (1 ) piloté entre l'entrée dudit accumulateur haute pression (41 ) et l'entrée de ladite pompe (30) en vis-à-vis dudit accumulateur haute pression (41 ); « un moyen piloté (3) entre l'entrée dudit accumulateur haute pression (41 ) et l'entrée dudit accumulateur basse pression (42); et • un multiplicateur de pression (2) entre l'entrée de ladite pompe (30) et l'entrée dudit moyen piloté (3) opposée audit accumulateur haute pression (41 ). La présente invention se rapporte également à un procédé de démarrage d'un moteur thermique (20) alimentant une pompe (30) dans un système hydraulique.
