fers ₈ so that when assembling the device the runner can be pushed through the opening formed by the ring 34 ₉ after which the sleeve 25 is placed on the ring 34 and the shaft journal 26 is inserted into the sintered bearing 28 ο

The blower housing can be enclosed by a protective housing / In the exemplary embodiment shown, a collar 20 is formed on the side wall of the blower housing ₉ which centers the blower housing and presses the man's shadow 19 against the ring 34 attacks the front face 32 with an outwardly drawn cylindrical ring in the collar 21 and holds and centers the blower housing also on the housing cheek 15 "Iteoh over = correct deviations from the circular symmetry on the collar and ring is also the direction of the axis of the outlet «= diffuser against the outflow opening 4 (with lamellae 8). On the same side, the ring presses the motor 15 into its receptacle 21 via a compression spring interposed to compensate for length tolermes = the front disk 37 of the rotor sits conically _{with a central P.} Countersunk = th hole 38 on the stub shaft. 39 of the motor "IJ ₀ ". _{P can} also occur if the axes of the motor and rotor are not cursed ₉ jamming at this bearing position _o A helical spring 40 (Figo I) _{9 serves as a coupling}

Trad sits firmly on the stub shaft with a hair = needle-shaped arm 41 (Figo 2) bent radially and axially into a recess 42 of the face plate 37. Because the spring creates a form fit between the stub plate and part stump at only one point and at the same time exerts a slight thrust on the runner in the direction of the thrust _{bearing 29 from 9} so that all radial and axial bearing play ₉ that could lead to fluttering noises and premature wear _{9 is} eliminated «,
