Drop tube segments adapted for use with a liquid reservoir

Image Number 4 for United States Patent #7243675.

A drop tube segment is adapted for use with a liquid reservoir. The drop tube segment includes a conduit with an end portion and a sidewall including a sidewall portion at least partially defining an interior housing area. The drop tube segment further includes a valve assembly comprising a valve member attached to the end portion of the conduit, a float, and a linkage device pivotally connected to the valve member. The valve assembly further includes a driver member at least partially disposed in the interior housing area. An adjustment of the float may rotate the driver member to engage the linkage device to facilitate in adjusting the position of the valve member with respect to the end portion of the conduit. The valve assembly further includes a structure adapted to inhibit, such as prevent, fluid from leaking into the interior housing area.
