Abstract

La présente invention concerne un système pour entrainement d’un élément mobile, comprenant au moins un dispositif d’entrainement (A, B) comprenant :- un moteur principal (M11, M12), configuré pour être relié à la première ligne d’alimentation (10), - un moteur secondaire (M21, M22) multi-cylindrée, configuré pour être relié à la deuxième ligne d’alimentation (12) et comprenant deux demi-moteurs (V1, V2) correspondant à deux niveaux de cylindrées (V1, V1+V2), dans lequel le premier demi-moteur (V1) est couplé en série avec le moteur principal (M11, M12) via une ligne de série (L10A, L10B), - une valve de mise à vide (20A, 20B) pilotée à l’aide d’une ligne de pilotage (25A, 25B) et configurée pour activer ou désactiver le deuxième demi-moteur (V2), - une ligne supplémentaire d’alimentation (L11A, L11B) configurée pour être reliée à la première ligne d’alimentation (10) et reliée au deuxième demi-moteur (V2),dans lequel la valve de mise à vide (20A, 20B, 20) est en outre pilotée à l’aide d’un rétrocontrôle s’opposant au pilotage par la ligne de pilotage (25A, 25B, 25), ledit rétrocontrôle étant effectué par une ligne de rétrocontrôle (27A, 27B, 27) prélevant sur la ligne supplémentaire d’alimentation (L11A, L11B, L11). Figure pour l’abrégé : Fig. 4The present invention relates to a system for driving a mobile element, comprising at least one driving device (A, B) comprising: - a main motor (M11, M12), configured to be connected to the first supply line (10), - a secondary engine (M21, M22) multi-displacement, configured to be connected to the second supply line (12) and comprising two half-motors (V1, V2) corresponding to two levels of displacement (V1 , V1 + V2), in which the first half-motor (V1) is coupled in series with the main motor (M11, M12) via a serial line (L10A, L10B), - a vacuum valve (20A, 20B) controlled using a control line (25A, 25B) and configured to activate or deactivate the second half-motor (V2), - an additional supply line (L11A, L11B) configured to be connected to the first supply line (10) and connected to the second half-motor (V2), in which the vacuum valve (20A, 20B, 20) is further controlled using a feedback control opposing the steering by the control line (25A, 25B, 25), said feedback being performed by a feedback line (27A, 27B, 27) taking from the additional supply line (L11A, L11B , L11).
