CONSTANT PRESSURE REGULATION OF GRADER BLADES

摘要

: By providing the work blade of a grader with a hydraulic regulation system where pressure limiting valves (14,15,16,17) guide pressure reducing valves (10,11,12,13) a constant pressure regulation of the work blade is achieved so that the work pressure set by the operator from his cab is maintained almost independent of the irregularities of the underlying surface.
