Abstract

Készülék üzemanyag befecskendezéséhez egy befecskendező egységgel (1),egy nyomóteret (13) tartalmazva, amelytől kiindulva egy magasnyomásúvezeték (5) nyúlik ki egy befecskendezőegység-házon (2) keresztül,amelyben egy szeleptűvel (4) lezárható fúvóka (3) van elrendezve, ahola szeleptűhöz (4) egy erőtároló (7) segítségével ömlik be azüzemanyag. Egymástól függetlenül beállítható és egy működtetőelemen(11) keresztül szabályozható szabályozószelepek (8, 10) állnakrendelkezésre és azok egymással össze vannak kötve egy csatolótéren(9) keresztül, amelyekkel a befecskendezőnyomás-felfutásszabályozható.
