Abstract

A találmány szerinti üzemanyag-befecskendező szerkezetnek van egynagynyomású üzemanyag-szivattyúja (10) és egy üzemanyag-befecskendezőszelepe (12) a belső égésű motor egy hengeréhez. A nagynyomásúüzemanyag-szivattyúnak (10) van egy szivattyúmunkatere (22), és azüzemanyag-befecskendező szelepnek (12) van egy befecskendezőszelep-tagja (28), amelynek révén legalább egy darab befecskendezőnyílás (32)vezérelve van, és amely egy zárórugó (44) ereje ellenébennyitóirányban (29) mozgatható; emellett a zárórugó (44) egyik oldalona befecskendezőszelep-tagra (28) támaszkodik, a másik oldalon pedigegy eltolható tárolódugattyúra (50), amelyre a zárórugóval (44)átellenes oldalán a szivattyúmunkatérben (22) uralkodó nyomás hat. Atárolódugattyú (50) a zárórugó (44) ereje ellenében bemozgatható egytárolótérbe (54), és a tárolódugattyúnak (50) a tárolótérbe (54)irányuló kitérő löketmozgása határolva van egy ütközővel (53). Atárolódugattyúnak (50) van egy nagyobb és egy kisebb keresztmetszetűszárszakasza, amelyek közül kiindulási helyzetben a kisebbkeresztmetszetű szárszakasz egy összekötő furatban (56), a nagyobbkeresztmetszetű szárszakaszpedig a szivattyúmunkatér (22) felé azösszekötő furaton (56) kívül van elhelyezve; és a tárolódugattyúnak(50) a tárolótérbe (54) irányuló kitérő löketmozgása közben a nagyobbkeresztmetszetű szárszakasza az összekötő furatba (56) besüllyed.
