Abstract: An adjustable nozzle comprising a nozzle body with an inlet, an outlet, and a passageway having a smooth bore extending between the inlet and the outlet. The passageway has an inner dimension transverse to the central axis of the nozzle and a compressible wall wherein the inner dimension is adjustable to adjust the flow rate through the nozzle.

Abstract: A firefighting device comprising includes a device body with a fluid passage through which a fluid flows when the firefighting device is in operation and at least one molded body. At least a portion of the molded body is at least translucent and encloses therein or covers a light emitting source. When light is emitted from the light emitting source, light is emitted from the molded body to thereby illuminate the firefighting device.

Abstract: A fire fighting fluid delivery system includes a fire fighting fluid delivery device, a pressure sensor, which senses fluid pressure at the fluid delivery device and generates a pressure signal indicative of the fluid pressure, and a wireless transmitter for transmitting the pressure signal. The fluid delivery system further includes a fire fighting fluid input device which is in fluid communication with the fluid delivery device and a wireless receiver that receives the pressure signal. In addition, the system includes a pressure gauge in communication with the receiver, which displays a pressure reading based on the pressure signal received by the receiver wherein a pump operator may selectively adjust the delivery of fluid to the fluid delivery device from the fluid input device based on the pressure reading displayed at the pressure gauge.
