To control two hydraulic circuit independently with only one pump, based on the existing two outlet axial piston pump, the dual discharging axial piston pump that divides the draining flow distributing window into two tandems is suggested. The corresponding two outlets connect two different circuits respectively. In order to verify the feasibility of the design, the simulation model of this type of pump is established under multi-disciplinary simulation software SimulationX. The pressure and flow characteristics in the single plunger between the transition region of two series window are analyzed. By simulating, the structure of the valve plate is determined, further a prototype is manufactured and tested. Experimental results validate the correctness of the simulation results. The research work lays the theoretical foundation for dual discharging axial piston pump to further application.
