PURPOSE: A sequence flow distribution valve is provided to accurately operate each actuator according to purposes of an operator without a throttling device when the actuators affected by variable loads. CONSTITUTION: A sequence flow distribution valve comprises a slot pipe(110), a spiral bush(120), and guide pipes(130). The slot pipe comprises a slot(111) extended along a longitudinal direction. The spiral bush is coupled to the outside of the slot pipe. The spiral bush comprises multiple outlets(121) spirally arranged to have each different phase angle. The guide pipes are coupled to the outside of the spiral bush. The guide pipes are connected to a hydraulic line extended from each actuator. The guide pipes are moved according to pilot signals and discharged flow rate is controlled by varying number of the occupied outlets. |
