摘要
分析了齿侧间隙很小时直齿轮泵和斜齿轮泵困油容积的变化规律，得出困油容积变化为二次抛物线的定量结论。
Spur gear pump and helical gear pump for the change law of trapping volume is analyzed. The quantitative conclusion that the change curve of trapping volume is quadratic parabola. The unloader channel which gear pump eliminate trapping from is designed.
