Fuel injecting valve for fuel injection system of internal-combustion engine, has narrow side surfaces of injecting opening tapering in flow direction convergent to each other such that opening tapers in flow direction
The valve has a valve seat body (16) with a firm valve seat (29), and a valve closing body (7) that co-operates with the valve seat. The closing body is axially moved along a valve longitudinal axis (2), and a discharging opening (27) is provided in the seat body. A spraying device is formed as a multi fan jet nozzle (23), and a slot-shaped injecting opening is provided in the jet nozzle. Narrow side surfaces of the injecting opening taper in a flow direction convergent to each other such that the injecting opening tapers in the flow direction by decreasing a length of a slot.
