| Abstract: | Based on the dimensional analysis and concept of equivalent diameter,a formulae for calculating the flow resistance of a ball is modified,so that the relationship between the flow resistance of the valve core and it's position in the Venturi terminal variable air valve can be obtained.A design scheme of spring with equal pitch in cylinder is proposed. |
