Abstract (en)
[origin: WO9628218A1] A sprinkler head triggering apparatus, comprising a spray nozzle with an actuator (14) being releasable by heating to a certain temperature, and which normally holds a valve piston (15) in a closed position against a valve seat. The valve piston, at release of the actuator, is movable in a piston sleeve in the direction away from said seat, for opening a flow passage (19-22) from a feed line for pressurized water to the spray nozzle. The flow passage (19-22) is openable in the normal closed position of the valve piston (15) with intact actuator (14), via a remote control operated pilot piston (32).
