Embodiment Construction
[0023] figure 1 A vacuum line 10 is schematically shown formed from two line parts 12 , 13 which are connected to one another via a vibration damper 14 . In the operating state, negative pressure is distributed in the vacuum line 10 and atmospheric pressure is distributed outside the vacuum line 10 .
[0024] The upper piping part 12 includes a vertical outer tube 18 into which a vertical inner tube 20 fits. The diameter of the outer tube 18 and inner tube 20 may be circular, but need not be. The cross-sectional profile of the outer tube 18 and the inner tube 20 may be cylindrical, but need not be.
[0025] The opening edge 42 of the inner tube 20 is connected with the opening edge 19 of the outer tube 18 through a flexible stretch sleeve 30, which is formed by a flexible but inelastic or little elastic sleeve hose 32. form. The opening edges of the sleeve hose 32 are connected in a vacuum-tight manner to the corresponding opening edges 19 , 42 of the outer tube 18 and the...
