ABSTRACT:
A fluid dispensing nozzle construction and method of making the same are provided, the construction comprising a valve body having a dipensing spout extending therefrom, and a flexible bellows-like tube of polymeric material telescopically disposed on the spout and having opposed ends one of which is secured to the valve body and the other of which carries a face seal means for engaging an annular lip of a fill pipe of a fluid storage tank to seal around an opening in the fill pipe when the spout is inserted therein, the spout and the tube defining a vapor recovery passage therebetween that leads from the seal means to the valve body. The spout has a valve seat member thereon and the tube carries a valve member that moves therewith and that cooperates with the valve seat member to close the passage intermediate the seal means and the valve body when the tube is in a certain first compressed condition thereof between the seal means and the valve body and to open the passage when the tube is in a certain greater compressed condition thereof between the seal means and the valve body. The valve member has an internal annular surface that slides over at least part of the valve seat member in sealing engagement therewith to close the passage when the tube is in the first compressed condition thereof.
