摘　　要： 本文首先导出了滚动活塞式压缩机回流系数的计算公式,并借助于计算机求解,绘制出工程计算用回流系数曲线;最后通过对计算结果及回流系数曲线的分析讨论,提出了确定吸气孔口角的原则。 The calculation equation of the back-flow coefficient of rolling piston type rotary conpressors has been derived in this paper. In terms of many solutions of the equation by computer, the general curves of the back-flow coefficient for engineering design are plotted. Finally, the principle to determine suction port angle has been reported by analyzing the results and the curves.
