<p>The circuit breaker has a main nozzle for a sensor jet, and catch nozzle, opposite to the main nozzle, and aligned with it. The sensor jet is surrounded by a fluidic protective jacket (7). The main nozzle (1) and/or catch nozzle (3) are surrounded by ring nozzles (10) which form the fluidic jacket. The ring nozzles are formed as a continuous ring gap, with individual apertures along the ring surface. The aligned ring nozzles diverge outwards, and eject diverging jets, meeting on a dam ring surface between the main and catch nozzles.</p> |
