Abstract
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.
