ABSTRACT:
A sealing device for use with a liquid dispensing nozzle assembly having a nozzle housing with an elongated discharge spout, a flexible vapor collector surrounding the spout with one free end and the other end attached to the nozzle housing or in proximity thereto, and provided with a means to recover vapor during delivery of liquid from the spout to a liquid receiver inlet which includes a mounting means affixed to the free end of the vapor collector, a flexible member with an interior chamber affixed to the mounting means so that it will contact the receiver inlet when the spout is inserted in the receiver inlet, and a fluid material substantially filling the interior chamber of the flexible member and which will allow the flexible member to conform to a geometry of the receiver inlet. Moreover, an improved liquid dispensing nozzle assembly includes a liquid-dispensing nozzle means, a flexible vapor collector means forming a chamber around the upper portion of the nozzle spout, a face means which includes the sealing device located adjacent to one end of the vapor collector for forming a seal with the outer surface of the liquid receiver inlet, and at least two spring members each of which act to extend the flexible vapor collector means, each of these spring members having one end attached to a different point of the face means so that the face means has substantially free rotational movement transverse to the axis of the nozzle spout.
