Abstract

Az üzemanyag-befecskendező szerkezetnek van egy nagynyomású üzemanyag-szivattyúja (10) és egy üzemanyag-befecskendező szelepe (12) a belsőégésű motor egy hengeréhez. A nagynyomású üzemanyag-szivattyúnak (10)van egy szivattyúmunkatere (22), és az üzemanyag-befecskendezőszelepnek (12) van egy befecskendezőszelep-tagja (28), amely révénlegalább egy darabbefecskendezőnyílás (32) vezérelve van, és amely egyzárórugó (44) ereje ellenében nyitóirányban (29) mozgatható; emelletta zárórugó (44) egyik oldalon a befecskendezőszelep-tagra (28)támaszkodik, a másik oldalon pedig egy eltolható tárolódugattyúra(50), amelyre a zárórugóval (44) átellenes oldalán aszivattyúmunkatérben (22) uralkodó nyomás hat. Atárolódugattyú (50) azárórugó (44) ereje ellenében bemozgatható egy tárolótérbe (55), és atárolódugattyúnak (50) a tárolótérbe (55) irányuló kitérő löketmozgásahatárolva van egy ütközővel (54). A tárolódugattyúval (50) együttmozgatható egy szárrész (52), amelynek van egy nagyobb és egy kisebbkeresztmetszetű szárszakasza, amelyek közül kiindulási helyzetben akisebb keresztmetszetű szárszakasz az összekötő furatban (53), anagyobb keresztmetszetű szárszakasz pedig az összekötő furaton (53)kívül, a tárolótérben (55) van elhelyezve; és a tárolódugattyúnak (50)a tárolótérbe (55) irányuló kitérő löketmozgása közben a nagyobbkeresztmetszetű szárszakasz az összekötő furatba (53) besüllyed.
