ABSTRACT:
An improved liquid-dispensing nozzle and more specifically, an improved vapor recovery means for a nozzle comprising a vapor collector surrounding a portion of the discharge spout in spaced relation thereto, one end of which is sealed to the upper portion of the nozzle housing or in proximity thereto; and at the other end of the vapor collector, a compressible cellular plastic material overlay on an equalizer means associated therewith. When the discharge spout is inserted into, e.g., an automobile fillpipe, the compressible cellular plastic material forms a vapor seal with the upper end of the fillpipe whereby the vapors escaping from the fillpipe are directed into the interior chamber formed between the exterior of the discharge spout and the inside of the vapor collector thereby minimizing the escape of vapors to the atmosphere. The vapors are then removed from this chamber. Also disclosed is a sealing device for use with a liquid dispensing nozzle assembly including a nozzle housing with an elongated discharge spout and a flexible vapor collector surrounding the spout with one free end and the other end attached to the upper portion of 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 including a mounting means affixed to the free end of the vapor collector, a sealant material means affixed to the free end of the vapor collector for contact with the receiver inlet, and an equalizer means affixed to the mounting means and interposed between the mounting means and the sealant material means so as to urge the sealant material means toward the receiver inlet when the spout is inserted in the receiver inlet.
