ABSTRACT:
A nozzle and method for generating foam is disclosed which includes a nozzle body, a nozzle inlet, an orifice, a gas inlet, an impingement pin and a nozzle outlet. The nozzle body has upstream and downstream ends and an inner wall defining a passage within the nozzle body. The nozzle inlet at the upstream end of the nozzle body permits introduction of a liquid foam producing agent into the passage. The foam producing agent then passes through the orifice, thereby forming a stream. This stream is directed past the gas inlets in the nozzle body to aspirate gas into the passage. The stream then impinges against the impingement pin which is disposed transversely across the passage. At least the upstream half of the cross-section of the impingement pin is annular so that the impingement pin disrupts the flow of the stream and splits it into secondary streams. These secondary streams pass outwardly on each side of the impingement pin and diverge with respect to each other prior to being deflected inwardly off the inner wall of the nozzle body. The nozzle outlet comprises a transverse slot disposed parallel to the impingement pin so that a thorough mixing between the gas and foam producing agent is effected prior to discharge through the nozzle outlet as foam.
