Abstract

Przedmiotem wynalazku jest liniowy silownik elektrohydrauliczny (7) zawierajacy: uklad wspólosiowych cylindrów z komora przelewowa (A) i mala (C) i duza (B) komora cisnieniowa, oraz sterujacy jego praca zespól zaworowy (8); i napedzany za posrednictwem nakretki kulowej (12) zainstalowanej na srubie napedzanej silnikiem (13). Silownik zawiera: nieruchome tloczysko (16); przemieszczalne tloczysko (17) polaczone z nakretka kulowa (12), uszczelnione wzgledem nieruchomego tloczyska (16) pierwszym uszczelnieniem i zawierajace cylinder nurnikowy (22), przy czym nieruchome tloczysko (16) jest uszczelnione wzgledem tloczyska (17) drugim uszczelnieniem; element koncowy (18), z którego wychodza tuleja prowadzaca (24), cylinder zewnetrzny (25) i nurnik (19), przy czym tuleja prowadzaca (24) otacza tloczysko (17), z którym jest polaczona suwliwie osiowo i nieobrotowo i którego powierzchnia jest uszczelniona wzgledem tej tulei prowadzacej (24) czwartym uszczelnieniem, a cylinder zewnetrzny (25) otacza nieruchome tloczysko (16), przy czym cylinder zewnetrzny (25) jest uszczelniona wzgledem nieruchomego tloczyska (16) piatym uszczelnieniem na cylindrze zewnetrznym (25) i szóstym uszczelnieniem na nieruchomym tloczysku (16), zas nurnik (19) jest wprowadzony do cylindra nurnikowego (22), uszczelnionego wzgledem nurnika (19) trzecim uszczelnieniem; natomiast komora przelewowa (A) jest zdefiniowana miedzy tloczyskiem (17), nieruchomym tloczyskiem (16), cylindrem zewnetrznym (25) i pierwszym, drugim, piatym i szóstym uszczelnieniem; duza komora cisnieniowa (B) jest zdefiniowana miedzy elementem koncowym (18), tuleja prowadzaca (24), cylindrem zewnetrznym (25), tloczyskiem (17), nieruchomym tloczyskiem (16) i drugim, czwartym i szóstym uszczelnieniem; mala komora cisnieniowa (C) jest zdefiniowana miedzy cylindrem nurnikowym (22), nurnikiem (19) i trzecim uszczelnieniem, przy czym zespól zaworowy (8) laczy komore przelewowa (A): z akumulatorem (9) bezposrednio, oraz z duza komora cisnieniowa (B) przez zawór sterowalny, a takze mala komore cisnieniowa (C): z duza komora cisnieniowa (B) przez zawór sterowalny oraz z akumulatorem (9) przez zawór zwrotny.
