ABSTRACT:
An electrically driven air pump having a housing, a pump mechanism in the housing and an electric motor in the housing connected in driving relation to the pump mechanism. Two spaced elastic supports support the electric motor from the housing at opposite ends of the motor. An air passage in the housing provides a flow of air past the electric motor to the pump mechanism. The air passage includes a suction nozzle supported by one of the elastic supports for supplying air to an inlet collar of a pump impeller of the pump mechanism. The suction nozzle projects into the collar for supply of the air from the electric motor to the pump mechanism.
