Nozzle for fire fighting device utilized in e.g. library, has suction port formed in runner element such that fire extinguishing agent exerts repulsive rotational torque on runner element to rotatably displace runner element

摘要

The nozzle (1) has a dispensing arrangement (3) exhibiting a suction port for spraying fire extinguishing agent i.e. water, toward a fire source. The dispensing arrangement has a stand element communicating with a fire extinguishing agent port (2) and a runner element rotatably connected with the stand element around a rotational axis. The suction port is formed in the runner element such that the fire extinguishing agent exerts repulsive rotational torque on the runner element to rotatably displace the runner element around the rotational axis during spraying of the agent. An independent claim is also included for a fire fighting device.
