Fallrohr-Vorrichtungen geeignet zum Gebrauch mit einem Flüssigkeitsreservoir

摘要

Drop tube assemblies are provided and adapted for use with a liquid reservoir. One exemplary drop tube assembly includes a first conduit, a second conduit (102) and a valve assembly (110). The valve assembly includes a valve member (112), a float (130), and a linkage device (170) pivotally connected with respect to the valve member. The linkage device is adapted for communication with the float such that the float may facilitate in adjusting the position of the valve member with respect to a first end portion of the second conduit in response to a liquid level in a liquid reservoir. The drop tube assembly further includes an adjustable stop member (188) engaging the second conduit and adapted to engage the linkage device to limit a movement of the linkage device.
