  • To spatially 90 ° offset also opens a second inlet line 12 with one end 13 in the receiving shaft 11.
  • This second inlet line 12 is 14 at its other end connected to an auxiliary suction opening 15 of the vacuum cleaner housing 2.
  • a third inlet line 16 opens into the direction offset by a further 90 ° Receiving shaft 11.
  • the third inlet line 16 thus forms an extension to the first inlet line 8 and is with a main suction opening 17 of the vacuum cleaner housing 2 connected.
  • a three-way valve 18 is rotatably arranged in the receiving shaft 11.
  • the Direction of rotation of this three-way valve 18 is indicated by an arrow 19.
  • the Three-way valve 18 has a continuous bore channel 20 and one in the Angle of 90 ° arranged duct connection 21, which with one end in the through bore channel 20 opens.
  • the bore channel 20 opens out with both Ends in through opening formed on the outer circumference of the three-way valve 18 22.
  • the duct connection 21 also opens into one at its other end such through opening 22.
  • the through openings 22 are on the circumference of the Three-way valves 18 each offset by 90 ° spatially.
  • a spring 23 is installed under the three-way valve 18.
  • This Spring 23 is designed both as a spiral spring and as a coil spring. Consequently can this spring 23 on the one hand a torque and on the other hand a compressive force exercise.
  • the spring 23 is at one end 24 in one at the bottom of the Three-way valves 18 provided groove-shaped recess 25 inserted.
  • By one the end 24 of the spring 23 is formed on an elastic wall part 26 secured in the trough-shaped recess 25.
  • the spring 23 is thus in the axial direction supported on the body of the three-way valve 18.
