Abstract

Un sistema di iniezione di combustibile per un motore a ciclo Diesel a molti cilindri comprende almeno una pompa, ogni pompa comprendendo un corpo tubolare (10) avente un gradino interno (11) contro cui è posizionato un cilindro di pompa flangiato (12). Una coppia di blocchi valvolari (22, 23) sono montati, estremo contro estremo, fra il cilindro e un blocco di montaggio (24) e il blocco di montaggio è fissato al corpo da bulloni (25) fornenti una forza di bloccaggio che garantisce una tenuta di liquido fra le facce presentate dei blocchi e il cilindro. Una camera cilindrica (14) nel cilindro alloggia un pistone di pompaggio (15) e i blocchi valvolari ricevono rispettivamente una valvola di erogazione (41) e una valvola di versamento (26). La valvola di versamento è controllata da una valvola elettromagnetica (38) montata sul blocco di montaggio.
