Damping device for a manipulator

摘要

The manipulator has a damping device (D) comprising a damping valve (11) i.e. 4/3-way control valve, arranged between a pressure source (P) and working pipelines (12) of a cantilever lifting cylinder (8). The damping valve is arranged parallel to a main valve (9) of the lifting cylinder. The damping valve is actuated by a controller (C) for oscillation damping in the lifting cylinder independent of the main valve. The damping valve is fitted without nozzles in flow paths in an application direction to the lifting cylinder and fitted with nozzles in a discharge direction.
