Abstract
A suction tube with a switching element for longitudinal adjustment of different tube sections ( ), particularly a suction tube having a drum switch ( ). The invention provides for sealing strips ( ) or sealing rings ( ) which are supported inside the suction tube casing ( ). This results in a relative movement between the drum switch ( ) and the sealing elements fixed to the casing. The positioning of the sealing elements in the suction tube casing ( ) is advantageous for assembly and allows for better compensation of tolerances in the sealing gap between the drum switch ( ) and the suction tube casing ( ).
