dans lequel une pompe hydraulique de dispositif de rotation (22, 25) destinée à entraîner un dispositif de rotation de l'engin de travail est prévue, de l'énergie accumulée de l'accumulateur à haute pression (40) pouvant être transmise aux autres pompes et/ou à un moteur diesel par le biais de la pompe de dispositif de rotation (22, 25). - Dispositif selon la revendication 1, caractérisé en ce que le vérin de travail est un vérin de flèche pour une flèche de l'engin de travail.
- Dispositif selon la revendication 1 ou 2, caractérisé en ce que le couplage différentiel à soupape d'étranglement comprend une soupape d'étranglement entre le côté fond et le côté tige du vérin de travail.
- Dispositif selon la revendication 1, 2 ou 3, caractérisé en ce que, dans la troisième zone, le fluide hydraulique s'écoule du côté fond au côté tige du vérin de travail.
- Dispositif selon l'une des revendications précédentes, caractérisé en ce que la pompe « Mooring » (21) fonctionne en circuit ouvert.
- Dispositif selon l'une des revendications précédentes, caractérisé en ce que le fluide hydraulique s'écoule simultanément ou en parallèle dans une, deux ou trois des zones.
- Dispositif selon l'une des revendications précédentes, caractérisé en ce que, en cas de panne du dispositif, une fonction de secours est prévue pour le fonctionnement de l'engin de travail.
- Engin de travail, en particulier pelle hydraulique, comprenant un dispositif selon l'une des revendications 1 à 7.
