A foam-applying nozzle including a generally hollow housing. An eductor disposed in the housing has a generally hollow body with a wall, the hollow of the body forming an eduction chamber. An eductor inlet and an opposing eductor outlet are in fluid communication with the eduction chamber. A plurality of jet inlets extend into the wall of the body, the jet inlets terminating in jet ports that are in fluid communication with the eduction chamber. The jet inlets are configured to receive a predetermined portion of a pressurized fluid, the portion exiting through the jet ports generally toward the eductor outlet, creating a vacuum in the eduction chamber. The vacuum is configured to draw a foam solution into the eductor inlet, the foam solution mixing with the aforementioned portion of pressurized fluid in the eduction chamber to form a foam mixture. |

1. A foam-applying nozzle, comprising: a generally hollow housing; and
an eductor disposed in the housing, the eductor comprising: a generally hollow body having a wall, the hollow of the body forming an eduction chamber disposed centrally within the housing, an eductor inlet and an opposing eductor outlet, the eductor inlet and eductor outlet being in fluid communication with the eduction chamber, and a plurality of jet inlets terminating in jet ports directed into the eduction chamber, the jet inlets being-configured to receive a predetermined portion of a pressurized fluid, said portion of the pressurized fluid directed through the jet ports generally into the eduction chamber toward the eductor outlet, creating a vacuum in the eduction chamber, the vacuum in the eduction chamber resulting in a foam solution being drawn into the eductor inlet, the foam solution mixing with said portion of pressurized fluid in the eduction chamber to form a foam mixture. |
