对于渐开线内啮合齿轮泵，作者计算了理想输送量、脉动系数和截留容积的变化。而这些特性都被他的实验所验证。研究结果清楚地发现，内啮合齿轮泵比传统的外啮合齿轮泵具有以下优点：（1）输送脉动和输送压力小；（2）截留容积变化小，并且在没有泄压槽的该空间内不会出现极限压力上升或下降。
Concerning the involute profile internal gear pump, the author calculated the ideal delivery, its pulsation factor and the variation of the trapped volume. And these characteristics were verified by his experiment. As a result of this research it was found clearly that the internal gear pumps are more excellent than the conventional external gear pumps in the following points, (1) the pulsations of the delivery and the delivery pressure are small, (2) the variation of the trapped volume is small, and there is no extreme pressure rise nor decrease in this space with no relief groove.
