Zusammenfassung:The invention relates to the technology and equipment for injection of fluids and other flowable materials into cavity of metal structure thus applying a coating onto the inner surface of cavity and creating the anti-corrosion layer. The aim of invention is protection of cavity walls from exposure to corrosion. The device for applying a coating onto the inner surface of cavity wall (1) of metal structure (2) comprises a nozzle (3) connected through the dispenser (4) to the container (5) filled with the material (6) under pressure. The wall (1) is provided with two bore-holes (7) and (8). The bore-hole (7) is connected to the nozzle of injector (3), the bore-hole (8) through the sleeve (9) is connected to a suction pump, function of which is lowering the pressure in chamber's (10) input. The nozzle of ejector (11) is connected to the air compressor (12). The metal structure (2) during the application of coating is being filled with a foamed material. Izgudrojums attiecas uz tehnoloģijām un ierīcēm šķidrumu un citu plūstošu materiālu izsmidzināšanai un uzklāšanai uz metāliskās konstrukcijās (2) esoša dobuma iekšējās virsmas, lai uz tās izveidotu pretkorozijas pārklājumu. Piedāvātā ierīce metāliskās konstrukcijas dobuma iekšējās sienas (1) aizsardzībai pret koroziju satur sprauslu (3), kas caur dozatoru (4) ir savienota ar rezervuāru (5), kas piepildīts ar darba materiālu (6) zem spiediena. Metāliskās konstrukcijas sienā (1) ir izveidoti divi urbumi (7, 8). Urbums (7) ir savienots ar smidzinātāja sprauslu (3), bet urbums (8) caur uzmavu (9) ir savienots ar zemspiediena strūklas sūkņa kameras (10) ežektora (11) sprauslu, kas ir savienota ar gaisa kompresoru (12). Urbumi (7, 8) metāliskās konstrukcijas (2) korpusā ir piepildīti ar saputotu darba materiālu (6) un ir noslēgti ar skrūvēm (13). Starp metāliskās konstrukcijas (2) ārējo sienu un uzmavu (9) ir izvietots blīvējums (14).
