Abstract: A device for generating compressed air foam for use in fire suppression, the device may be attached to standard pressurized sources of water used for fighting fires. The device comprises a water chamber adjacent to an air chamber with a partition there between. A water impeller resides at least partially within the water chamber and an air impeller resides at least partially within the air chamber. The pressurized source of water drives the water impeller, which in turn is connected to drive the air impeller. The air impeller sucks air into the air chamber and compresses the air. The air then passes through a nozzle in the partition to aerate the source of water containing foam solutes to form compressed air foam. The compressed air foam exits the device with a velocity to coat a fire to be extinguished.

Abstract: In a nozzle, in a cross section including an axis of a nozzle body, a side surface and a seat surface are both smoothly connected to an arc of a circle inscribing both the side surface and the seat surface. A part of a needle which is adjacent to a tip end side of a seat portion is a cone having a diameter reduced toward a tip end side of the cone in the axial direction. Thus, no corner is on the seat surface or the side surface, and the two surfaces form one curved surface. Since a cavitation generated in a sack chamber can be reduced, even when an injection quantity is significantly small such that an injection port does not throttle an injection flow, a flow coefficient of the injection flow is improved and a penetration of a spray of the fuel can be maintained.
