Definitions

the invention relates to an electrically driven air pump, for example for motor vehicles, in which so-called secondary air is to be conveyed into the exhaust pipe system in order to improve the exhaust gas values.
the object of the invention is to create an air pump with reduced running noise, with a simplified pump structure also being achieved.
the housing 1 is on the electric motor side by a cover 5 and on the pump side by a cover 6 locked.
the housing 1 has an air supply connection 7, which opens into an annular channel 8 arranged around the electric motor chamber 3. From this ring channel 8, the sucked-in air passes through a filter insert 9 into a chamber 10 formed by the cover 5 and from there via several passages 11 of an elastic motor mounting 12 into the electric motor chamber 3 and from there via passages 13 of a second elastic motor mounting 14 into one this motor mounting 14 attached suction funnel 15, a partial flow directly via cooling air channels, not shown, of the electric motor into the suction funnel 15, which protrudes into an inlet collar 16 of a pump impeller 17.
the rotating impeller 17 sucks air and conveys it in an arranged in the housing 2, the outer edge of the pump wheel 17 partially encompassing annular channel 18, from which it flows through a pressure connection 19 to a consumer, not shown.
the impeller 17 is fastened on a shaft 20 of the electric motor 4.
the lower part of the ring channel 8 represents an extension into which a circuit board 21 is inserted, the connections 22 of which are led to the outside via a plug connection 23 arranged in the housing wall.
This extension is advantageously sealed off from the other part of the ring channel so that the circuit board is protected against moisture.
the air pump according to the invention With the air pump according to the invention, low-noise operation has become possible, since vibrations caused by the pumping station and the electric motor and low-frequency decay with a larger one are now possible Amplitude in the engine mounts are cushioned and no longer get into the housing 1 to a large extent.
the invention provides a very simple air pump that is inexpensive to manufacture and will have a long service life. Tighter tolerances are now possible in the pump plant, which increase the delivery rate.
