HYDRAULIC SYSTEM WITH OIL VENTILATION

The invention relates to an oil ventilation system for hydraulic circuits, wherein the hydraulic system comprises at least one hydraulic motor arrangement (34) and a hydraulic fluid reservoir (44) hydraulically coupled to this hydraulic motor arrangement (34), and to the at least one hydraulic motor arrangement (34) a suction device (42) for suction of the hydraulic fluid (43) is assigned in such a way that the suction device (42) by means of negative pressure (p) discharges hydraulic fluid from the hydraulic motor arrangement (34) into the hydraulic fluid reservoir (44). Furthermore, the invention comprises a use of such a system in mobile work machines (60).
