[0031] FIG. 8 schematically shows an exploded view of components of the ventilator according to the disclosure with an impeller and an adapter flange provided between the impeller and the electrical drive as well as with the electrical drive itself.

[0032] It is noted at first as regards the figures and the following description of the figures that only those structural components are described and provided with reference numerals here which have a relationship with the teaching according to the disclosure. For the sake of a simple presentation, the presenting and explaining of other features concerning the ventilator are not made.

[0033] FIG. 1 shows an impeller 1 as a component of a ventilator according to the disclosure. This impeller 1 is to be connected on the output side to a drive unit which is not shown. In order that this connection can take place without screws, special connection means or connectors 2 are provided there which is designed as engagement elements 3. The engagement elements 3 have a button-like/mushroom-like an inserting head 4 and a thinner insertion neck 5. The engagement elements 3 are arranged in a circle and fastened on an integral annular flange 6.

[0034] FIG. 2 shows the previously discussed features on account of the somewhat different view in detail, in particular as regards the design of the insertion elements 3 with insertion head 4 and insertion neck 5.

[0035] The insertion elements 3 of the impeller 1 shown in the FIGS. 1 and 2 correspond to engagement openings 7 which may be directly associated on the output side with a connection area of an adapter flange which is not shown.

[0036] FIG. 3 shows in detail the annular flange 6 of the impeller 1 according to FIGS. 1 and 2, wherein catch means or catch 13 in the form of catch grooves 14 are provided outside on the annular flange 6 in the direct vicinity of the insertion element 3.

[0044] FIG. 8 shows components of the ventilator according to the disclosure in an exploded view. The electrical drive 17, which is not shown in FIGS. 1 to 7, is indicated. An adapter flange 8 is provided for the connection of the impeller 1 to the drive 17, which flange is screwed to the drive 17.

[0045] The adapter flange 8 is provided with a device for protection against rotation, for example, with positioning pins 18 or screws for the non-rotating positioning on the drive 17. Parts of the connection means 2 are provided on the adapter flange 8 along the circumference, namely, engagement openings with a larger insertion range 9 and a narrower shifting range 10. The ramp-like support surface 11 and the ramp surface 12 are indicated.

[0046] Complementary connection means 2 is provided on the impeller 1 along an annular flange 6. This connection means 2 comprises engagement elements 3 with insertion head 4 and insertion neck 5.
