Abstract

RADNI UREDJAJ ZA PREKIDAČ STRUJE GASA, pronalazak se odnosi na radni uredjaj (1) za prekidač struje gasa koji obuhvata radni klip (3) koji je smešten u radni cilindar (2) tako da može da se kreće u oba smera izmedju prvog (3a) i drugog položaja (3b). Pri tome radni klip (3) deli unutrašnji prostor radnog cilindra (2) na prvu (2a) i drugu komoru (2b). Radni klip (3) se pomera iz prvog (3a) u drugi položaj (3b) u vreme operacije prekidanja radnog uredjaja, dok se radni klip (3) pomera iz drugog (3b) u prvi položaj (3a) u vreme zatvaranja radnog uredjaja. Izduvni otvor (7) radnog cilindra (2) je povezan sa prvom komorom (2a) kada je radni klip (3) u blizini drugog položaja (3b), dok je izduvni otvor (7) povezan sa drugom komorom (2b) kada je radni klip (3) udaljen od drugog položaja (3b). U prvu (2a) komoru se uvodi vazduh pod visokim pritiskom u vreme operacije prekidanja. Radni uredjaj (1) takodje uključuje uredjaj (4) sa izduvnim ventilom za izbacivanje vazduha iz prve komore (2a). Uredjaj (6) sa izduvnim ventilom uključuje ventilski element (11) koji ima deo (11a) za preuzimanje pritiska i koji preuzima pritisak vazduha iz prve komore (2a). Deo za preuzimanje pritiska (11a) je tako postavljen da je van kontakta sa radnim klipom (3) kada se radni klip nalazi u prvom položaju (3a).
