Abstract

A female nozzle of a connection comprising a tubular main body defining a main axis of insertion and having a connection end adapted to receive a male nozzle, one retaining ring inserted into the main body on the connection end side, one internal annular recess having a bottom, a first and a second side wall, with the bottom and the first wall being defined by an internal shoulder of the main body and the second wall being defined by a circular section of the retaining ring, and with the annular recess not being contained in a transversal plane, which is perpendicular to the main axis of insertion and a sealing gasket being positioned in the annular recess. The first and second side walls are oriented toward the bottom of the annular recess, so that the latter has a trapezoidal section so configured as to clamp and hold the sealing gasket.

First claim

What is claimed is:

1. A female nozzle of a connection, comprising:
a tubular main body defining a main axis of insertion and having one connection end adapted to receive a male nozzle;
a retaining ring inserted into the tubular main body on the one connection end, the retaining ring having a circular section, wherein the retaining ring carries at least one alignment pin configured to be received in an alignment recess provided on the tubular main body;
an internal annular recess having a bottom wall, a first side wall, and a second side wall, the bottom wall and the first side wall being defined by an internal shoulder of the tubular main body, the second side wall being defined by the circular section of the retaining ring, the internal annular recess not being contained in a transverse plane, perpendicular to the main axis of insertion of the tubular main body, the first side wall and the second side wall being oriented toward the bottom of the internal annular recess such that the internal annular recess has a trapezoidal cross-section; and
a sealing gasket positioned in the internal annular recess, the sealing gasket being clamped and held in the internal annular recess.

2. The female nozzle of claim 1 , wherein the bottom wall of the internal annular recess has a dimension greater than a diameter of a section of the sealing gasket.

3. The female nozzle of claim 2 , wherein the retaining ring comprises at least one notch provided in one opening of the tubular main body to maintain the retaining ring in the tubular main body.

4. The female nozzle of claim 3 , wherein the retaining ring and the tubular main body comprise clip recesses aligned with one another, and wherein the female nozzle further comprises a jumper clip engaged into the clip recesses of the retaining ring and of the tubular main body.

5. The female nozzle of claim 4 , wherein the retaining ring includes a first segment and a second segment, the first segment having an outer diameter greater than an outer diameter of the second segment, a peripheral section of the first segment of the retaining ring abutting against a bearing shoulder of the tubular main body.

6. The female nozzle of claim 1 , wherein the retaining ring comprises at least one notch provided in one opening of the tubular main body to maintain the retaining ring in the tubular main body.

7. The female nozzle of claim 1 , wherein the retaining ring and the tubular main body comprise clip recesses aligned with one another, and wherein the female nozzle further comprises a jumper clip engaged into the clip recesses of the retaining ring and of the tubular main body.

8. The female nozzle of claim 1 , wherein the retaining ring includes a first segment and a second segment, the first segment having an outer diameter greater than an outer diameter of the second segment, a peripheral section of the first segment of the retaining ring abutting against a bearing shoulder of the tubular main body.

9. A female nozzle of a connection, comprising:
a tubular main body defining a main axis of insertion and having one connection end adapted to receive a male nozzle;
a retaining ring inserted into the tubular main body on the one connection end, the retaining ring having a circular section, wherein the retaining ring comprises at least one notch provided in one opening of the tubular main body to maintain the retaining ring in the tubular main body;
an internal annular recess having a bottom wall, a first side wall, and a second side wall, the bottom wall and the first side wall being defined by an internal shoulder of the tubular main body, the second side wall being defined by the circular section of the retaining ring, the internal annular recess not being contained in a transverse plane, perpendicular to the main axis of insertion of the tubular main body, the first side wall and the second side wall being oriented toward the bottom of the internal annular recess such that the internal annular recess has a trapezoidal cross-section; and
a sealing gasket positioned in the internal annular recess, the sealing gasket being clamped and held in the internal annular recess.

10. The female nozzle of claim 9 , wherein the bottom wall of the internal annular recess has a dimension greater than a diameter of a section of the sealing gasket.

11. The female nozzle of claim 9 , wherein the retaining ring carries at least one alignment pin configured to be received in an alignment recess provided on the tubular main body.

12. The female nozzle of claim 9 , wherein the retaining ring and the tubular main body comprise clip recesses aligned with one another, and wherein the female nozzle further comprises a jumper clip engaged into the clip recesses of the retaining ring and of the tubular main body.

13. The female nozzle of claim 9 , wherein the retaining ring includes a first segment and a second segment, the first segment having an outer diameter greater than an outer diameter of the second segment, a peripheral section of the first segment of the retaining ring abutting against a bearing shoulder of the tubular main body.

14. A female nozzle of a connection, comprising:
a tubular main body defining a main axis of insertion and having one connection end adapted to receive a male nozzle;
a retaining ring inserted into the tubular main body on the one connection end, the retaining ring having a circular section;
an internal annular recess having a bottom wall, a first side wall, and a second side wall, the bottom wall and the first side wall being defined by an internal shoulder of the tubular main body, the second side wall being defined by the circular section of the retaining ring, the internal annular recess not being contained in a transverse plane, perpendicular to the main axis of insertion of the tubular main body, the first side wall and the second side wall being oriented toward the bottom of the internal annular recess such that the internal annular recess has a trapezoidal cross-section; and
a sealing gasket positioned in the internal annular recess, the sealing gasket being clamped and held in the internal annular recess;
wherein the retaining ring and the tubular main body comprise clip recesses aligned with one another, and wherein the female nozzle further comprises a jumper clip engaged into the clip recesses of the retaining ring and of the tubular main body.

15. The female nozzle of claim 14 , wherein the bottom wall of the internal annular recess has a dimension greater than a diameter of a section of the sealing gasket.

16. The female nozzle of claim 14 , wherein the retaining ring carries at least one alignment pin configured to be received in an alignment recess provided on the tubular main body.

17. The female nozzle of claim 14 , wherein the retaining ring comprises at least one notch provided in one opening of the tubular main body to maintain the retaining ring in the tubular main body.

18. The female nozzle of claim 14 , wherein the retaining ring includes a first segment and a second segment, the first segment having an outer diameter greater than an outer diameter of the second segment, a peripheral section of the first segment of the retaining ring abutting against a bearing shoulder of the tubular main body.
