ABSTRACT:
An electrical air pump adapted for being periodically turned on and off and reversed in pumping direction. The air pump includes an electric motor adapted for electronic control and an air pump section joined by a housing as a common system. The housing has a cylindrical wall defining a first chamber in which the stator system is received and a scaling cover is engaged with the housing to seal the first chamber. The air pump section includes a pump cover sealingly engaged with the housing and defining therewith a second chamber, the rotor being of bell shape and rotatably supported in the second chamber on a pin secured in the housing and in the pump cover. The rotor is disposed with slight clearance adjacent to an end wall of the housing and the rotor projects radially beyond the cylindrical wall. The rotor has a collar and a plurality of pumping blades extending radially from the collar into an annular pumping channel of the second chamber. The pump cover has two connections, one for aspirating air and the other for discharging air under pressure, connected to the annular channel and angularly spaced from one another. The pump cover has a wall with a separating section of locally increased thickness between the two connections.
