Definitions

the invention relates to an electrically driven air pump, for example for Motor vehicles in which so-called secondary air enters the exhaust pipe system Internal combustion engine is to be promoted to improve the exhaust gas values.
DE-A1 41 07 049.6 has already proposed that the electric motor by means of two elastic motor bearings between Electric motor and housing is supported. With the in this publication The proposed pump impeller is made up of several parts composite impeller, which must be balanced.
a pump version is known from US Pat. No. 2,857,849, for example several pump impellers are attached to an electric motor shaft, by means of a screw screwed into the pump impeller hub transversely to the longitudinal axis of the pump, that pushes against the shaft. Given that the thread is sufficient for this purpose must be firm, it can be concluded that the impellers are made of metal. This are heavy and have imbalances.
the invention has for its object an air pump with a reduced To create running noise and simplified pump construction.
Fig. 1 shows the air pump according to the invention, consisting of a housing 1, the on the one hand accommodates a pump unit 2 and on the other hand in an electric motor chamber 3 an electric motor 4.
the housing 1 is closed on the pump side by a cover 5, which has an intake port 6.
the pump unit 2 has one or more pump impellers 7. 8, which are made of Plastic existing pump impeller hubs 9, 10 on an electric motor shaft 11 are pressed on.
these impeller hubs 9, 10 have 12 adhesive joints 13 in their shaft receiving opening which exist between the pressing surfaces of the impeller hubs 9, 10 and the motor shaft 11 and are filled with adhesive 14.
the adhesive joints 13 are designed as longitudinal joints or spiral joints and advantageously have a thickness of approximately 0.05 mm.
the pump impeller hubs 9, 10 made of plastic can be produced in one piece with the pump impeller 7, 8 in one injection process or can be injection molded onto a pump impeller plate (not shown separately) forming the pump impeller.
