Vapor recovery apparatus employing dispensing nozzle with condensing capacity

摘要

A conventional liquid dispensing nozzle with connecting liquid line is adapted to include a flexible, annular sealing means with a plurality of concentric holes disposed therein; a plurality of refrigerant expansion coils; and a projecting condensate portion mounted on the emission end portion of the dispensing nozzle. Refrigerant supply and return lines communicate through the annular sealing means with a conventional external refrigerant supply. The flexible annular sealing means accommodates a continuous seal with variously sized entry ports on liquid storage tanks when the dispensing nozzle is inserted into such tanks for liquid transfer. An alternative dispensing nozzle embodiment employs a detachable baffle means which includes an annular gasket and contiguous depending sleeve adapted to surround the inserted dispensing nozzle.
