Hydraulic system for operation of reversible hydraulic loader

摘要

A return flow of fluid from the hydraulic loader is choked, when the loader is externally driven. To achieve this the hydraulic system has a slider opening in a valve housing, through which a spring arrangement of a control slider (13) is centered in a middle position. The control slider can be moved in two directions. In the first position it connects the pressure line with a tank. A second slider (14) connects a second pressure line in a similar manner.
