Abstract

Az üzemanyag-befecskendező szerkezet egy nagynyomású üzemanyag-szivattyúval (10) és egy üzemanyag-befecskendező szeleppel (12)rendelkezik 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 a révén legalább egy befecskendezőnyílás (32)vezérelve van, és amely egy, a szivattyúmunkatérrel (22) összekötöttnyomótérben (40) uralkodó nyomás révén egy zárórugó (44) erejeellenében nyitóirányban (29) mozgatható, emellett a zárórugó (44)egyfelől a befecskendezőszelep-tagra (28), másfelől pedig egyeltolható kitérődugattyúra (50) támaszkodik, amely utóbbi azárórugóval (44) átellenes oldalán egy, a szivattyúmunkatérrel (22)összekötött előteret (85) határol. A kitérődugattyú (50) a zárórugó(44) ereje ellenében egy tárolótérbe (55) bemozgatható. Az előtér (85)egy első fojtáshelyen (84) keresztül a szivattyúmunkatérrel (22) összevan kötve, és az üzemanyag-befecskendező szelep (12) nyomótere (40) azelőteret (85) megkerülve egy második fojtáshelyen (93) keresztül aszivattyúmunkatérrel (22) össze van kötve.
