Hose connection

1. A hose connector ( 1 ) for a flexible hose line ( 5 ), comprising a sleeve-shaped union nut ( 2 ) which surrounds a sleeve-shaped connector part ( 3 ), said sleeve-shaped connector part is adapted to be connected to a hose end ( 4 ) of the flexible hose line ( 5 ) and has, at its end region oriented away from the hose end ( 4 ), an annular flange ( 6 ) which bears rotatably against an annular shoulder ( 7 ) of a circumferential wall ( 8 ), at least one sealing ring ( 9 ) which is held in a retaining groove ( 10 ) provided on an outer circumferential side of the connector part ( 3 ) and radially seals an annular gap provided between the connector part ( 3 ) and the circumferential wall ( 8 ), and a clearance is provided between the connector part ( 3 ) and the circumferential wall ( 8 ), and between a sleeve inner circumference of the union nut ( 2 ) and the hose line ( 5 ), the clearance is dimensioned such that the connector part ( 3 ) and the circumferential wall ( 8 ) are tiltable with respect to one another, an intermediate ring ( 12 ) which includes the annular shoulder ( 7 ) on the circumferential wall ( 8 ) bounding an annular opening, said intermediate ring ( 12 ) is held rotatably on an inner circumference of the union nut ( 2 ), and the intermediate ring ( 12 ) includes, on an outer circumferential side of an end region thereof oriented away from the hose end ( 4 ), an annular flange ( 13 ) that extends radially outwardly, said annular flange ( 13 ) bears against an annular shoulder ( 14 ) provided on the inner circumference of the union nut ( 2 ).

2. The hose connector as claimed in claim 1 , wherein the retaining groove ( 10 ) has a groove bottom ( 11 ) which is configured as a convex curve.

3. The hose connector as claimed in claim 1 , wherein the annular flange ( 6 ) is rotatable about a longitudinal axis relative to the annular shoulder ( 7 ) of the circumferential wall ( 8 ).

4. The hose connector as claimed in claim 1 , wherein an annular seal ( 15 ) bears against an end side, oriented away from the hose end ( 4 ), of the intermediate ring ( 12 ) and the annular seal ( 15 ) axially seals an annular gap between an outer circumference of the intermediate ring ( 12 ) and the inner circumference of the sleeve-shaped union nut ( 2 ).

5. The hose connector as claimed in claim 4 , wherein the sealing ring ( 9 ) and also the annular seal ( 15 ) are made of an elastic material.

6. The hose connector as claimed in claim 5 , wherein an end face of the connector part ( 3 ) that is oriented away from the hose end ( 4 ) is spaced apart from an adjacent end side of the annular seal ( 15 ).

7. The hose connector as claimed in claim 4 , wherein the annular seal ( 15 ) is disk-shaped.

8. The hose connector as claimed in claim 1 , wherein the annular flange ( 6 ) provided on the connector part ( 3 ) has a stepped configuration and includes, on a flange inner side oriented toward the hose end ( 4 ), an annularly circumferential rabbet ( 16 ), said rabbet ( 16 ) has an outer diameter that is smaller than a clear diameter of the intermediate ring ( 12 ).

9. The hose connector as claimed in claim 8 , wherein the connector part ( 3 ) is tiltable between a zero position arranged coaxially or axially parallel with a longitudinal axis of the union nut ( 2 ), and a tilted position away from the longitudinal axis of the union nut ( 2 ), and in the tilted position, the rabbet ( 16 ), provided on the annular flange ( 6 ) of the connector part ( 3 ) and the annular shoulder ( 7 ) engage with one another at least in a part region of the circumference.

10. The hose connector as claimed in claim 1 , wherein an edge that bounds the retaining groove ( 10 ) and is oriented toward the hose end ( 4 ) is configured as a circumferential projection ( 17 ).

11. The hose connector as claimed in claim 10 , wherein a part region of the connector part ( 3 ) that is oriented toward the hose end ( 4 ) has an outer diameter which is smaller than an outer diameter of the projection ( 17 ).

12. The hose connector as claimed in claim 1 , wherein the sealing ring ( 9 ) has a round ring cross section.

13. A hose line assembly comprising a flexible hose line and the hose connector as claimed in claim 1 .
