Hydraulic arrangement, has rinsing unit controlling pressure medium connection between pressure lines and tank, and hydropneumatic accumulator connected with pressure lines by slide valve

摘要

The arrangement has a closed hydraulic circuit in which a hydraulic motor (4) and a hydro pump (2) are arranged. The motor and the pump are connected with each other by low pressure lines (6, 8). A feed unit (14) guides pressurizing medium from a tank (12) into the respective low pressure lines. A rinsing unit (10) controls pressure medium connection between the pressure lines and the tank. A hydropneumatic accumulator (16) is connected with the pressure lines by a slide valve (18) e.g. flush valve, loading valve and feeding valve.
