ABSTRACT:
A fluid conveying device has a main housing and a rotor housing which accommodates an impeller. The rotor housing is located inside the main housing and cooperates with the latter to form a motor chamber and an intake chamber. The two chambers are disposed on opposite sides of the rotor housing and communicate with one another via connecting passages. The main housing is provided with apertures which connect the motor chamber to the atmosphere, and a motor for the impeller is mounted in the motor chamber behind the apertures. The main housing is further provided with an outflow opening which faces the intake chamber, and a discharge opening which leads out of the main housing. The outflow opening is connected to a source of gas containing combustible components. The rotor housing has an inlet which opens to the intake chamber and registers with the outflow opening in a non-concentric manner, and an outlet which communicates with the discharge opening. When the motor is switched on, the impeller draws air into the motor chamber via the apertures. The air cools the motor and is then drawn to the rotor housing inlet through the connecting passages. The gas with the combustible components is also drawn to the rotor housing inlet by the impeller. At the inlet, this gas is combined with the cooling air. The impeller expels the resulting mixture from the main housing via the rotor housing outlet and the main housing discharge opening.
