FIELD: fire-fighting equipment.
SUBSTANCE: invention is designed to create a manual ejector fire hose nozzle with broader functionality and efficiency. For this, at the input of the hose nozzle in the housing the ejector is installed comprising a vacuum chamber connected by its nozzle with a flow of water at the inlet, and at the outlet - in the canal inside the stock - with a diffuser, and is connected to the foam-generator through suction channels in the water-damper, as well as through a distribution chamber, a fitting, a flow control and a vacuum tube connected to the tank of foam-generator.
EFFECT: invention can significantly increase the efficiency of manual fire hose nozzles, using water or foam depending on the operational situation, selecting the desired flow of water or foam in a wide range.
