摘要： A rotatable cam limit switch with a switch operating cam mounted directly on a continuously rotating drive shaft and axially shiftable relative to the shaft. The drive shaft is also provided with a "fast thread" for adjustable axial positioning of a timing element in slidable engagement with the cam. Manual axially adjustable yoke elements respectively engage the cam and timing element for establishing preselected switch dwell time and phase relationship between said switch and said shaft.
摘要翻译：可旋转的凸轮限位开关，其具有直接安装在连续旋转的驱动轴上并且相对于轴可轴向移动的开关操作凸轮。驱动轴还设置有“快速螺纹”，用于可调节的轴向定位元件与凸轮滑动接合。手动可轴向调节的轭元件分别接合凸轮和定时元件，以建立所述开关和所述轴之间的预选开关停留时间和相位关系。

摘要： A pressure control assembly having a snap-acting Belleville washer responsive to fluid pressure, and a switch actuating mechanism movable therewith, includes an adjusting mechanism for the snap-acting Belleville washer. The adjusting mechanism includes at least one pin which can be moved along the surface of the Belleville washer to change the Belleville washer's pivot point by increasing or decreasing its lever arm, thus varying its snap pressure. In the preferred embodiment, there are three pins which extend through aligned slots in an upper and lower plate and the pins can be moved radially inwardly and outwardly by rotating the lower plate relative to the upper plate.
摘要翻译：一种压力控制组件，其具有响应于流体压力的快速作用的百叶窗垫圈，以及可与其一起移动的开关致动机构，包括用于该卡扣式贝氏垫圈的调节机构。调节机构包括至少一个可沿Belleville垫圈表面移动的销，通过增加或减小其杠杆臂来改变Belleville清洗器的枢轴点，从而改变其卡扣压力。在优选实施例中，有三个销延伸穿过上板和下板中的对准的槽，并且销可以通过相对于上板转动下板而径向向内和向外移动。
