在丙烯酸树脂制轴向柱塞泵中，用频闪仪和高速摄影法观察汽蚀现象，并测量缸内压力变化。空化分为以下两组：一组与截留现象有关，可通过阀板的适当设计来防止，而另一组与截留现象无关，主要在流道收缩和/或扩大后的剪切层中观察到。在这种情况下，对应于冲击压力出现的最小可测量气缸压力小于10 kPa。本文还研究了水-乙二醇液压液中的空化现象。
In an axial piston pump made of acrylic resin, cavitation is observed by the naked eye with a strobo-scope and by high speed photography, and the pressure changes in the cylinder are measured. The cavitation is classified into the following two groups ; one, related to the trapping phenomenon, can be prevented by a suitable design of valve plates, while the other, not related to the trapping phenomenon, is mainly observed in shear layers after the contraction and/or the enlargement of flow passages. In this case, the minimum measurable cylinder pressure corresponding to the appearance of a shock pressure is less than 10 kPa. The cavitation is also studied in a water-glycol hydraulic fluid.
