According to the invention, this object is achieved by the fact that, in these motor oil pumps, the pump housing is extended to the support of the motor stem and _{: is placed} on the shaft of the motor rotor and the bevel wheel, so that the Blower fan then motor sweeps away. The lamp housing for this purpose has been quickly preserved, which does not only carry the hotprestand on struts or dergleieiieji, but also at the same time the blower housing that is to be formed as an IMiibe ams. Advantageously, this Flunsea has correspondingly spaced-apart diaphragms with an associated- · "adjustable fade-in. Through the breakthroughs, the combustion air is sucked in and can be adjusted;

The assembly of a soiphen unit is particularly easy, when the runner is glued to the lielle, the wrapped Stand held on it adjusted. and in this position the bleeh package of the stand with the * * provided webs is glued to the flange if necessary using absorbent intermediate layers that form a form fit after the adhesive has hardened. This type of assembly eliminates the need for turning work on the stand sheet metal package? and aia Slanscih- " The 'fan wheel can either be opened with a! Tab on the.

The fan wheel with the blades 8 and the side wall ) can either be placed non-rotatably with a hub 10 on the protruding end 11 of the shaft 7 or it can be riveted with a cup-shaped indentation 12 of the side wall 9 onto the short-circuit ring 13 by means of the rivets cast onto it be.

The housing flange has perforations 15i distributed around the circumference through which the combustion air is sucked in. With. An adjustable ring diaphragm, not shown, these openings are to be partially closed. For better Air duct, the flange has an annular web 16 with one of the Fan wheel of approximately the same diameter, the height of which extends up to the blades 8. At this ring web 16 or at the edge of the flange 2 is also expedient not shown To attach the fan housing.

When assembling the unit, the rotor 6 placed on the shaft 7, then the bull 3 on the webs 4, whereby it by means of in the air gap between rotor 6 and stand 3 inserted spacers, so-called spies, centered until the adhesive 5 hardens between the stand 3 and webs 4- is held. The spies are then taken out and attached the fan wheel.

This simplified design and construction results in a considerable cost savings with the same performance effect. In addition, the unit is compact and less stressed Space*
