The study introduces a method which can eliminate pressure jump when asymmetrical cylinder is moves backward. It shares the flow of the cylinder non-rod end chamber by auxiliary servo valve to guarantee symmetrical flow of main servo valve. The paper gives an overview of the program principles, theoretical analysis and calculation; at last, it makes simulation based on software of AMESim. Results show that this method can eliminate pressure jump of cylinder when moves backward. This method can bring new applications to engineering practical value.
