housing for the sealing device or more precisely with a wall segment 110 u2032 of the housing and a second element 160 which pivots around element 158 the second element 160 can be attached to the feeder tube segment 120 from the outside the first element 158 is directly flanged with a flange section 159 to the housing wall 110 u2032 this turns the housing 110 into a structural support for the feeder tube swivel bearing according to the design shown in fig4 the second element 160 is seated radial on the first element 158 via two cylinder bearings 162 163 in this assembly the second element 160 and the cylinder bearings reside inside the housing or precisely at the inner wall of housing 110 u2032 the feeder tube 120 with flange 156 is inserted in the first element 158 of the feeder tube swivel bearing the swivel bearing is sealed from the feeder tube using two o rings 166 167 which are seated around the outer feeder tube on the seal surface 164 the fill material is usually pushed under pressure from the fill unit into the feeder tube and the seal keeps it from entering the feeder tube swivel bearing 140 furthermore clamping 168 reversibly connects the feeder tube 120 at its flange 156 with the second element 160 of the swivel bearing 140 the feeder tube position is therefore radial to the first element 158 and opposite the housing once the clamp 168 is opened the feeder tube can be.
