Apparatus for improving the replicability of the injection duration on injection systems
The invention relates to an apparatus for injecting fuel, having a control valve ( 16 ) that has a valve chamber ( 18 ). From the valve chamber ( 18 ), a high-pressure line ( 37 ) leads to the injector; the valve chamber ( 18 ) also communicates with a pump chamber ( 23 ) for fuel that is at high pr...

| Zusammenfassung: | The invention relates to an apparatus for injecting fuel, having a control valve (
16
) that has a valve chamber (
18
). From the valve chamber (
18
), a high-pressure line (
37
) leads to the injector; the valve chamber (
18
) also communicates with a pump chamber (
23
) for fuel that is at high pressure. The control part of the control valve (
16
) is actuatable by means of an electromagnet (
17
). The control valve (
16
) is coupled with a passive piston (
20
), which to avoid the pulse change, which acts on the piston (
20
), is provided with a bore (
21
). |
