Abstract
DIFERENCIJALNI HIDRAULIČNI CILINDAR SA SISTEMOM AMORTIZERA ZA UPRAVLJANJE ELEKTRIČNIM PREKIDAČIMA, koji obuhvata cilindar (2), klip (6) sa klipnjačom (8) koji u cilindru obrazuju prstenastu komoru (10) sa jedne strane klipa, i glavnu komoru (12) sa druge strane klipa, pri čemu je klipnjača (8) povezana sa pokretnim kontaktom prekidača, a prstenasta komora (10) je stalno povezana sa izvodom (20) hidrauličnog fluida visokog pritiska, dok glavna komora (12) ima na dnu cilindra u čauri (14) otvor (16) za napajanje/ispuštanje fluida, gde je na donjoj strani klipa (6), na njegovoj čeonoj površini (60) okrenutoj glavnoj komori (12) načinjen produžetak (42), prilagodjen da sadejstvuje sa amortizacionim prstenom (44) slobodno postavljenim oko otvora (16) za napajanje/ispuštanje, naznačen time, što na klipu (6) nema nikakve zaptivke prema cilindru (2), što prsten (44) obrazuje graničnik hoda klipa (6), što prsten (44) ima na svojoj radijalnoj prstenastoj površini (52), okrenutoj glavnoj komori (12), prvu prstenastu zaptivnu zonu (54), a na suprotnoj radijalnoj prstenastoj površini (56) drugu prstenastu zaptivnu zonu (58), pri čemu su prva i druga zaptivna zona (54), (58) podešene da obrazuju prvi i drugi zaptivni ventil sa donjom površinom (60) klipa (6) i čaurom (14) na dnu cilindra kada je klip (6) na kraju hoda. Prijava sadrži još 9 zavisnih zahteva.
