 Working Principle

  Motor drives the pump shaft through the coupling rotation, the electric energy into hydraulic energy, the pump suction from the tank, high pressure oil discharged by reversing the proportion valve, drive tanks work. Proportional valve for the control cylinder liter reduction, was electric, the cylinder piston rod indentation. Proportional pressure relief valve
