伺服最小压力阀
摘要：
一种伺服最小压力阀组件包括伺服最小压力套和伺服最小压力阀芯。伺服最小压力套包括入口孔、第一窗组、第二窗组和第三窗组。第一窗组的出口窗直径与第二窗组的出口窗直径的比率在2.34和2.65之间。第二窗组的出口窗直径大于第三窗组的出口窗直径。伺服最小压力阀芯构造成沿伺服最小压力阀套的纵轴线双向地移动。伺服最小压力阀芯包括圆柱部分以控制伺服最小压力套的入口孔和伺服最小压力套的第一、第二和第三窗组之间的流体流量。
摘要（英）：

A servo minimum pressure valve assembly includes a servo minimum pressure sleeve and a servo minimum pressure valve spool. The servo minimum pressure sleeve includes an inlet aperture, a first window set, a second window set, and a third window set. A ratio of an outlet window diameter of the first window set to an outlet window diameter of the second window set is between 2.34 and 2.65. The outlet window diameter of the second window set is greater than an outlet window diameter of the third window set. The servo minimum pressure valve spool is configured to move bi-directionally along a longitudinal axis of the servo minimum pressure valve sleeve. The servo minimum pressure valve spool includes a cylindrical portion to control a fluid flow between the inlet aperture of the servo minimum pressure sleeve and the first, second, and third window sets of the servo minimum pressure sleeve.
