HYDRAULIC SYSTEM WITH AT LEAST ONE HYDROSTATIC DISPLACEMENT UNIT

摘要

The invention relates to a hydraulic system with at least one hydrostatic displacement unit (2, 4), a filter unit (6) for filtering the hydraulic oil flowing through the respective displacement unit (2, 4), and a discharge device (10) that filters the leakage oil accumulating at each displacement unit (2, 4) during operation and supplies it to a tank (8). The system is characterized in that the discharge device (10) has a pump device (26) by means of which the leakage oil can be brought to a pressure suitable for feeding to the filter device (6).
