Abstract

Disclosed is a novel nozzle assembly adapted to pass fluid, by means of a fluid outlet line, into any one of a plurality of tank lines, each of the tank lines defining a tank line port. The nozzle assembly is further adapted to receive vapors passing through the tank line port from any one of the tank lines.

Claims

1. A nozzle assembly adapted to pass fluid, by means of a fluid outlet line, into any one of a plurality of tank lines, each of said tank lines defining a tank line port;

said nozzle assembly being further adapted to receive vapors passing through said tank line port from any of said tank lines, the invention comprising;

spring means, secured to said fluid outlet line, having a member spaced therefrom;

said member being adapted to be compressed toward said fluid outlet line upon insertion of said fluid outlet line into any one of said tank lines for applying a force against said tank line to help maintain said fluid outlet line therein;

collar means, surrounding a portion of said fluid outlet line and overlapping at least a portion of said spring means, said collar means having a distal end, secured to said fluid outlet line, and a free proximal end, terminating in lip means adapted to form a seal about said tank line port upon insertion of said fluid outlet line into said tank line; and

vapor return means, at least partially defined by a space between said collar means and said fluid outlet line, for passing vapors from said tank line, whereby fluid may be passed from said fluid outlet line into said tank line, and vapors may be passed from said tank line into said vapor return means.

2. The nozzle assembly set forth in claim 1 wherein said member spaced from said fluid outlet line is bowed outwardly therefrom, and is adapted to frictionally engage the interior of said tank line to help maintain said lip means in sealed relationship about said tank line port.

3. The nozzle assembly set forth in claim 2 wherein said spring means include a plurality of bowed members spaced from said fluid outlet line, and wherein at least some of said bowed members define gaps therebetween to permit passage of said vapors from said tank line to said vapor return means.

4. The nozzle assembly set forth in claim 1 wherein said coller means include a plurality of pleats to permit the extension and retraction of said coller means relative to said fluid outlet line.

5. The nozzle assembly set forth in claim 1 wherein said collar means are resilient so that, upon retraction, said collar means are urged in the direction opposed to said retraction to help maintain said lip means in sealed relationship about said tank line port upon insertion of said fluid outlet line into said tank line.

6. The nozzle assembly set forth in claim 1 wherein said collar means include integral passage means at said distal end;

said integral passage means forming part of said vapor return means.

7. The nozzle assembly set forth in claim 6 wherein said vapor return means include a return line cooperating with said integral passage means for passing said vapors from said nozzle assembly.

8. The nozzle assembly set forth in claim 7 further including valve means, communicating with said vapor return means, for permitting the passage of said vapors from said tank line to said return line, and blocking the passage of said vapors from said return line to said tank line.

9. A nozzle assembly adapted to pass fluid, by means of a fluid outlet line, into any one of a plurality of tank lines, each of said tank lines defining a tank line part;

said nozzle assembly being further adapted to receive vapors passing through said tank line port from any of said tank line, the invention comprising;

spring means, secured about at least a portion of said fluid outlet line, including a plurality of members bowed outwardly from said fluid outlet line;

said bowed members being adapted to be compressed toward said fluid outlet line upon insertion of said fluid outlet line into any one of said tank lines for applying a force against said tank line to help maintain said fluid outlet line therein;

collar means, surrounding a portion of said fluid outlet line and overlapping at least a portion of said spring means, said coller means having a distal end, secured to said fluid outlet line, and a free proximal end, terminating in lip means adapted to form a seal about said tank line port upon insertion of said fluid outlet line into said tank line; and

vapor return means, at least partially defined by a space between said collar means and said fluid outlet line, for passing vapors from said tank line, whereby fluid may be passed from said fluid outlet line into said tank line, and vapors may be passed from said tank line into said vapor return means.

10. A nozzle assembly adapted to pass fluid, by means of a fluid outlet line, into any one of a plurality of tank lines, each of said tank lines defining a tank line port;

said nozzle assembly being further adapted to receive vapors passing through said tank line port from any of said tank lines, the invention comprising;

spring means, secured about at least a portion of said fluid outlet line, having a plurality of members defining gaps therebetween to permit passage of said vapors;

each of said members being spaced from said fluid outlet line, and being adapted to be compressed upon insertion of said fluid outlet line into any one of said tank lines for applying a force against said tank line to help maintain said fluid outlet line therein;

collar means, surrounding portion of said fluid outlet line and overlapping at least a portion of said spring means, said collar means having a distal end, secured to said fluid outlet line, and a free proximal end, terminating in lip means adapted to form a seal about said tank line port upon insertion of said fluid outlet line into said tank line; and

vapor return means, at least partially defined by a space between said collar means and said fluid outlet line, for passing vapors from said tank line, whereby fluid may be passed from said fluid outlet line into said tank line, and vapors may be passed from said tank line into said vapor return means.

11. A nozzle assembly adapted to pass fluid, by means of a fluid outlet line, into any one of a plurality of tank lines, each of said tank lines defining a tank line port;

said nozzle assembly being further adapted to receive vapors passing through said tank line port from any of said tank lines, the invention comprising;

spring means, secured to said fluid outlet line, having a member spaced therefrom;

said member being adapted to be compressed toward said fluid outlet line upon insertion of said fluid outlet line into any one of said tank lines for applying a force against said tank line to help maintain said fluid outlet line therein;

retractable collar means, surrounding a portion of said fluid outlet line and overlapping at least a portion of said spring means, said colalr means having a distal end, secured to said fluid outlet line, and a free proximal end, terminating in lip means adapted to form a seal about said tank line port upon insertion of said fluid outlet line into said tank line;

said collar means being resilient so that, upon retraction, said collar means are urged in the direction opposed to said retraction;

said spring means being urged against said collar means, prior to the insertion of said fluid outlet line into said tank line, to help maintain said collar in a retracted position, and said spring means, upon compression, permitting said collar means to be urged in the direction opposed to said retraction so that said lip means are maintained in sealed relationship about said tank line port when said fluid outlet line is thereafter inserted into said tank line; and

vapor return means, at least partially defined by a space between said collar means and said fluid outlet line, for passing vapors from said tank line, whereby fluid may be passed from said fluid outlet line into said tank line, and vapors may be passes from said tank line into said vapor return means.
