A sprinkler includes an inlet aperture, an outlet aperture, a body, a conical member, and a deflector. The inlet aperture receives fire suppressant agent at an inlet end of the sprinkler and the outlet aperture is at an outlet end of the sprinkler. The body extends along a longitudinal axis and includes an inner volume forming a fluid flow path between the inlet end and the outlet end of the sprinkler. The conical member is positioned at the outlet end of the sprinkler directs the fire suppressant agent outwards. The deflector receives fire suppressant agent from the conical member and distributes the fire suppressant agent about a service area. The deflector includes multiple tines, which each extend along a corresponding radial axis that is substantially perpendicular with the longitudinal axis. Each tine is offset by an angular amount about the corresponding radial axis.

A system for delivering a cooling agent to cooking appliance to aid in fire suppression is disclosed, which includes a fuel delivery path extending from a source of cooking fuel to a heating element of the cooking appliance, a source of cooling agent selectively in fluid communication with the fuel delivery path, and a valve assembly associated with the fuel delivery path and the source of cooling agent, wherein the valve assembly is configured to control the delivery of cooling agent to the heating element of the cooking appliance and shut off the heating element from the source of cooking fuel in the event of a fire.

The invention relates to a spray mist nozzle, in particular an open high-pressure spray mist nozzle for firefighting systems, having a housing which is configured with an extinguishing fluid inlet and is configured with multiple recesses for receiving an exchangeable nozzle insert, such a nozzle insert being inserted into one, multiple/plural or all the recesses. The nozzle insert has a main body with a longitudinal axis that has in the longitudinal axis a spray mist outlet for the extinguishing fluid. An exchangeable swirl body is arranged in the main body and is configured to swirl the extinguishing fluid prior to the latter exiting from the spray mist outlet. The spray mist outlet has a minimum opening cross section, and has a widened exit cross section downstream of the minimum opening cross section, wherein a transition from the minimum opening cross section to the exit cross section runs along a convexly curved surface.

A battery pack includes at least two battery modules arranged in one direction; and a fire extinguishing unit extinguisher having a fire extinguishing tank configured to contain a fire extinguishing agent therein, a pipe connected to the fire extinguishing tank to supply the fire extinguishing agent from the fire extinguishing tank to each of the at least two battery modules, a flow rate adjuster provided to the pipe and configured to adjust a feed flow rate of the fire extinguishing agent to be constant, and at least one valve configured to supply the fire extinguishing agent from the fire extinguishing tank to the battery module having an internal temperature rising over a predetermined temperature.

A battery arrangement for a motor vehicle, having a battery and an extinguishing agent supply device for guiding an extinguishing agent at the extinguishing agent supply device to the battery. The extinguishing agent feed device has a first connector coupling to an extinguishing agent reservoir external to the motor vehicle, a second connector connected to at least one component of the battery, and a line from the first connector to the second connector. The line includes at least one first line section which, with respect to an intended installation position of the battery arrangement in the motor vehicle, has a positive slope in relation to a horizontal and with respect to an extension direction of the line from the first connector to the second connector; and/or the extinguishing agent supply device has a closure element having an active locking mechanism which is unlockable or lockable by an associated unlocking unit.
