Abstract: Oil flow is regulated by the main float operating the inlet valve to maintain a constant level in the float chamber. Flow from the float chamber is metered by a selected metering orifice in the rotatable disc actuated by the knob. A detent arrangement assures registry of the proper orifice. The small safety float is mounted on the same pivot as the main float and normally moves with the main float but if the inlet valve should leak, causing the oil level in the float chamber to continue to rise to an abnormally high level, the safety float will rise until the ferrous part of the float support bracket comes into the field of the permanent magnet carried by the cover. At this time the float will be lifted with a snap action and the tab standing up from the safety float bracket will strike the arm standing up from the main float bracket. This will deliver a blow to the inlet valve and will maintain the added force on the inlet valve. The control cannot subsequently be placed into operation without first manually depressing the reset button to push the safety float away from the permanent magnet.

Abstract translation: 油流通过操作进气阀的主浮子来调节，以保持浮子室的恒定水平。 来自浮子室的流量由在由旋钮驱动的可旋转盘中的选定计量孔计量。 制动装置确保适当孔的注册。 小安全浮子安装在与主浮子相同的枢轴上，并与主浮子一起移动，但如果入口阀应该泄漏，导致浮子室中的油位继续上升到异常高的水平，安全浮子 将升起，直到浮子支撑支架的黑色部分进入由盖子所携带的永磁体的场中。 此时，浮子将以卡扣动作提升，并且从安全浮子支架悬挂的卡舌将使主臂从主浮子支架上抬起。 这将对入口阀产生冲击，并且将保持入口阀上的增加的力。 无需先手动按下复位按钮将安全浮子从永久磁铁上推开，则控制装置不能随后投入使用。
