Hose line, and filter screen for a hose line
A hose line ( 1 ) filter screen ( 12 ) having a sleeve-shaped hose connector ( 3 ) which by way of a first hose connector part-region that is configured as a connector port ( 4 ) projects through a hose opening that is provided at an end side ( 3 ) of the hose ( 2 ) into a contiguous hose end region of the hose ( 2 ), and which connector port ( 4 ) has a second hose connector part-region ( 6 ) which projects beyond the end side ( 3 ) of the hose ( 2 ), which second hose connector part-region ( 6 ) at the free end side thereof has an encircling seal retaining collar ( 7 ) that projects on the circumference. An annular flange ( 8 ) is provided on the circumference of the second hose connector part-region ( 6 ), and a union nut ( 9 ) engages behind said annular flange ( 8 ). An annular seal ( 10 ) is provided between the annular flange ( 8 ) and the seal retaining collar. The hose line ( 1 ) has a filter screen ( 12 ), which at the end side region thereof that faces the hose connector ( 4 ) is assembled on the seal retaining collar ( 7 ) of the hose connector ( 4 ).
1. A hose line ( 1 , 1 ′), comprising:
a flexible hose ( 2 );
a sleeve-shaped hose connector ( 3 ) having a first hose connector part-region configured as a connector port ( 4 ) that projects from a hose opening that is provided at an end side of the hose ( 2 ) into a contiguous hose end region of the hose ( 2 ) and a second hose connector part-region ( 6 ) which projects beyond the end side of the hose ( 2 ), an encircling seal retaining collar ( 7 ) is located at a free end side of the second hose connector part-region ( 6 ), the encircling seal retaining collar ( 7 ) projects about a circumference, and an annular flange ( 8 ) is provided on the second hose connector part-region ( 6 );
a union nut ( 9 ) that engages behind said annular flange ( 8 );
an annular seal ( 10 ) provided between said annular flange ( 8 ) and the seal retaining collar ( 7 ); and
a filter screen ( 12 , 12 ′) assembled on the seal retaining collar ( 7 ) of the hose connector ( 4 ) at an end side region thereof that faces the hose connector ( 4 ).
2. The hose line as claimed in claim 1 , wherein the filter screen ( 12 , 12 ′) is configured as a filter cap.
3. The hose line as claimed in claim 1 , wherein the filter screen ( 12 , 12 ′) on the end side region thereof that faces the hose connector ( 4 ) has at least one retaining element, configured as an inboard retaining flute or retaining groove ( 13 ), said at least one retaining element engages behind the seal retaining collar ( 7 ).
4. The hose line as claimed in claim 3 , wherein the retaining element is configured as an annular seat ( 14 ) which is molded to the filter screen ( 12 , 12 ′), said annular seat ( 14 ) on an internal annular circumference thereof includes the encircling retaining groove ( 13 ).
5. The hose line as claimed in claim 1 , wherein the filter screen ( 12 , 12 ′) is releasably assembled on the seal retaining collar ( 7 ).
6. The hose line as claimed in claim 2 , wherein the filter screen ( 12 ) at least in a part-region thereof that faces away from the hose connector ( 4 ) has a conical shape or a truncated cone shape.
7. The hose line as claimed in claim 1 , wherein the filter screen ( 12 ) has a cylindrical filter area on an external circumference thereof.
8. The hose line as claimed in claim 7 , wherein the filter screen ( 12 ) further comprises spacers ( 20 ) molded to an external circumference of the filter screen ( 12 ′) on the cylindrical filter area.
9. The hose line as claimed in claim 4 , wherein the annular seat ( 14 ) is molded as a flange to the filter screen ( 12 , 12 ′).
10. The hose line as claimed in claim 4 , wherein a maximum diameter of the filter screen ( 12 ) in a region of the annular seat ( 14 ) is dimensioned such that the annular seal ( 10 ) has an annular zone ( 15 ) that is disposed between the annular seat ( 14 ) of the filter screen ( 12 ) and an internal circumference of the union nut ( 9 ), and an annular or sleeve-shaped end side of a neighboring line portion is adapted to be brought to bear on said annular zone ( 15 ).
11. The hose line as claimed in claim 1 , wherein the hose line is a sanitary hose line which is adapted to connect an outlet fitting or a water dispenser point to an angle valve.
