  • the air distribution connection 63 is expediently assigned a fastening means 64 for the detachable and tight fastening of a fluid line.
  • valve member 4 formed by the multifunction unit 14 When the valve member 4 formed by the multifunction unit 14 is in the context of a linear switching movement 24
  • the cross-sectional contours are rectangular and in particular square.
  • the connecting body 7 has in particular the shape of a rectangular frame.
  • the housing main part 45 is expediently cuboid and in particular cube-shaped.
  • the housing main part 45 is here in particular a circular-cylindrical body.
  • the multifunction unit 14 is pivotable with respect to the connecting body 7 in a pivot plane, so that the switching movement for switching the shut-off valve is a pivoting movement.
  • the pivoting plane of the pivoting movement preferably runs parallel to the main axis 13.
  • the pivot axis of the pivoting movement expediently runs at right angles to the main axis 13.
  • the pivot axis extends parallel to and at a distance from an imaginary straight line connecting the center point of the opposing mouths of the inner end portions 8a, 9a of the air inlet port 8 and the air outlet laßan gleiches 9 together.
  • the mouths of the two end portions 26a, 26b of the working channel 26 move along a circular arc on which the mouths of the inner end portions 8a, 9a of the air inlet port 8 and the air outlet port 9 are located.
  • the pivot bearing of the multi-functional unit 14 can be realized for example by means of at least one bearing pin, which passes through the housing 5 and the connector body 7.
