Abstract
A fuel injector for internal combustion engines, comprising:
- a housing (16),
- a valve guide (38) fixed at a lower end of said housing (16), the valve guide (38) having a longitudinal guide bore (44) and a chamber (46) provided with a valve seat (50), said chamber (46) being connected to a fuel supply duct (22,48);
- an atomizer (56) fixed at a lower end of said valve guide (38), the atomizer (56) having a longitudinal bore (80) in flow connection with said chamber (46), the atomizer having a plurality of nozzle bores (82) having inlet openings (84) facing into said longitudinal bore (80);
- a spindle (88) having a valve portion (92) cooperating with said valve seat (50), and a cut-off element (94) extending into said longitudinal bore (80) of the atomizer (56), wherein an upper cut-off section (102) and a lower cut-off section (106) axially spaced apart from each other are defined between the outer surface of the cut-off element (94) and the inner surface of the longitudinal bore (80), cut-off sections (102,106) being both closed in the closed position of the spindle (88), the cut-off element (94) having a central duct (112) in flow connection with the longitudinal bore (80) of the atomizer (56) both above the upper cut-off section (102) and below the lower cut-off section (106).
