ABSTRACT:
An impeller is connected to a liquid-powered motor to be driven thereby. The impeller is of a type capable of moving a large volume of air of the order of as much as several thousand cubic meters per minute, which is ten or more times the volume of liquid used to power the motor. Some or all of the liquid applied to the motor to be transformed into mechanical energy is carried by a conduit to a point where it can suitably enter the air stream provided by the impeller. The conduit can carry the liquid to a point between the motor and the impeller so as to be picked up along with air and included in the stream forcibly projected from the impeller. Alternatively, the conduit can be routed around the impeller to discharge the liquid into the already formed air stream. The conduit for the liquid can be arranged to receive only liquid that has been used to supply power to the motor, or it can be provided with an additional inlet to receive one or more additional chemicals to improve the nature of the aerosol, which is the combined air and finely divided water particles propelled by the impeller.
