Abstract

A ventilating arrangement for a vehicle generator is proposed where a rotor-stator unit is arranged in a housing equipped with air-guiding ducts. A fan wheel is connected in front of this rotor-stator unit which by means of a pulley is drivingly held on a shaft of the rotor. The pulley is developed as an air delivery wheel and comprises supporting ribs forming radial guide blades. The air delivery wheel serves to partially compress and assist the air flow to the fan wheel.
