<p>Design method for cylinder for fluid transfer device Abstract The invention relates to a design method for the cylinder for a fluid transer device. The method comprises providing an input passage, an output passage and a receiving chamber; further providing a cylindrical valve chamber passing through the cylindre; arranging the 5 receiving chamber radial with respect of the valve chamber, providign 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 10 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 15 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 reasonalbe stress. F g. 1 Fig.1</p> |
