<p>A fuel injector for internal combustion engines, comprising:
- an atomizer (10) having a longitudinal bore (14) and a plurality of nozzle bores (16) having inlet openings (18) facing into said longitudinal bore (14), said inlet openings (18) being divided into an upper group and a lower group, spaced apart from each other in a longitudinal direction (A), and
- a cut-off element (22) extending into said longitudinal bore (14) of the atomizer (10), the cut-off element (22) being movable in said longitudinal direction (A) between an open and a closed position,
wherein the longitudinal bore (14) and the cut-off element (22) have respective upper and lower sealing portions (24, 28, 26, 30) cooperating with each other in said closed position of the cut-off element (22) to define an upper and a lower cut-off section (32, 34) which extend, respectively, above the upper group of inlet openings (18) and below the lower group of inlet openings (18).</p> |
