Fuel injecting valve for fuel injection systems of internal-combustion engines, has discharge ports consist of two sections, where lower downstream section has larger opening width than opening width of upper upstream section

摘要

The fuel injecting valve has valve longitudinal axis (2), a valve seat body (16) with a fixed valve seat (29), a valve closing body (7) cooperating with valve seat and axially movable along the valve longitudinal axis. The discharge ports (25) consist of two sections, which run asymmetrically to each other. The lower downstream section has larger opening width than the opening width of upper upstream section and lower displacement of down stream section is opposite to the upstream section. The down stream section on the inflow side is larger than that on opposite side of the discharge ports.
