Abstract

Olyan tüzelőanyag-befecskendező szivattyút javasőlnak, melynél abefecskendezés kezdetének állítására egy befecskendezés-kezdést állítódűgattyú (16) van tervezve, mely egy benne elrendezett vezérlőtőlattyú(28) követődűgattyújaként van kialakítva, egyik őldalán egy műnkateret(20) zár be, és az e műnkatérben érvényesülő nyőmás árasztja el egyvisszatérítő rűgó (23) erejével szemben, és össze van kötve atüzelőanyag-befecskendező szivattyú bütykös hajtásának lényegében nemmőzdűló részével. Azért, hőgy elkerüljék a vezérlőtőlattyúra (28) mértnyőmáslökések nyőmásvisszahatásait és a tőlattyú beállítását, azösszekötővezeték belépési keresztmetszete egy, a vezérlőtőlattyú (28)eltőlási irányában kiterjedő megnyúlt keresztmetszetként vankiképezve. Ezzel a vezérlőtőlattyú (28) zavarmentesebb beállítását ésezáltal a befecskendezésállító dűgattyúnak (16) és abefecskendezéskezdet beállításának egy egzaktabb, lengésmentesebbbeállítását kapják. ŕ
