Device for detachably fastening a bag filter dust in a vacuum cleaner apparatus powder.

Device for detachably fastening a bag filter dust in a vacuum cleaner dust, with a flange part (5) of a rigid material that settles out in the wall (2) of the bag having a hole of step (6) aligned with an inlet (3) in the wall (2) of the bag, and an adapter plate (7) of specific rigid material for the apparatus, which in turn can be fixed in the apparatus vacuum cleaner and on the other hand can be detachably attached to the flange part (5) through an attachment linker and retention, wherein the adapter plate (7) has a hole (11), that is united state aligned with the hole (6) of the flange (5), and together with it constitutes a flow orifice and in which there is an annular seal (14) active in connected state between adapter plate (7) and the flange (5) for sealing the flow bore outside, characterized in that the part d and flange (5) it can be fixed radially outside the annular seal (14) in the inclined position sloping away from the adapter plate (7) and in attached state is connected tilting to the adapter plate (7) so that the flange part (5) is tiltable adapter plate (7) in a use position arranged coaxial with the adapter plate (7) interlocked with the adapter plate (7), wherein a surface sealing ring (17) of the flange (5) or the adapter plate (7) is held against the ring seal (14) arranged on the adapter plate (7) or the flange section.
