Abstract (en)
[origin: EP0971168A2] A nozzle pipe (3) protrudes into the steam pipe and branches off from the cooling water supply unit (2) which has a regulator valve (4) regulating the water pressure (P2) in the nozzle (5)-pipe. Each nozzle has a tubular nozzle-pot (10) fixed in the nozzle pipe and crossing it. At least one water inlet (11) inside the nozzle-pipe is in the pot-casing. A spring-tensioned (12) nozzle pin (13) is positioned in the pot. A cap (15) is screwed onto the open end of the pot protruding from the pipe and has a spray hole (14) with which the end point (16) of the pin cooperates. The other end of the pin protruding from the pot base forms a piston surface exposed to steam pressure.(P1)
