Hydraulic control system for vineyard cultivator - has flow dividers supplying loads alternately without increasing pumping capacity

摘要

The hydraulic control system is used especially horticultural machines used in vineyards. The control system has two series connected flow dividers and a control valve. Additional loads are supplied while the main loads are not in use. This ensures power to the loads in operation without increasing the pumping capacity. The second flow divider (4) has a switching position (b) which bypasses the regulating system. In this bypass the flow stream (10) arriving from the first flow divider (3) is directed directly to the control valves (5 6). The switching position (b) of the second flow divider can be adjusted by a manually actuated mechanically fixed switching element (36).
