The invention relates to a design method for the cylinder. The method comprises providing a cylindrical valve chamber passing through the cylinder; arranging the receiving chamber radial with respect of the valve chamber, providing the receiving chamber with a cylindrical portion and a trumpet-shaped constriction portion coaxial with the cylindrical portion, arranging for the diameter of the head end of the constriction portion to be less than the interior diameter of the receiving chamber, communicating the tail ends of the receiving chamber, the input and passages with the valve chamber, arranging for the width of the tail end of the constriction portion to be greater than the width of the swinging range of the first passage, arranging for the minimal distance between the tail ends of the output and input passages to be greater than the width of the second passage. The cylinder of the invention achieves that fluid flows in one direction, and easy to mount, working steadily and reasonable stress. <Figure 5> |
