    Abstract: A standpipe extending upward from the bottom of a liquid container is provided with external helical square threads. A float fits over the standpipe and has a standpipe-operating rod extending down through the standpipe to a control switch below the container. The switch controls a valve for filling the container with liquid to a predetermined liquid level. The float is provided with a sheet metal nut having inwardly projecting teeth engaging the helical threads for rotating the float as the changing liquid level raises and lowers the float relative to the standpipe.

    Abstract translation: 从液体容器的底部向上延伸的立管设置有外螺旋方螺纹。 浮子装在立管上,并有一个竖管操作杆,通过立管向下延伸到容器下方的控制开关。 开关控制用于将液体填充到预定液位的阀。 浮子设置有金属板螺母,其具有与螺旋螺纹接合的向内突出的齿,用于随着变化的液位升高而使浮子旋转,并相对于竖管降低浮子。
