    摘要： A fuel injection valve (10) has a valve member (2) arranged to be controllably movable in an axial direction toward and away from a circular valve seat (4) so as to control fuel flow from a port (5) downstream from the valve seat. An axial fuel passage (7) extends from upstream of the valve seat (4) through a clearance between the seating portion and the seat (4) for producing a substantially non-swirling fuel flow from the port (5). A transverse fuel passage (8) is also provided and the transverse fuel passage extends transversely to the axial passage and communicates with the axial fuel passage at a location offset to a diameter of the valve seat for producing a swirling fuel flow from the port (5). A combination of swirling and non-swirling fuel flow is thus supplied by the port (5), for producing finer fuel droplets of improved distribution.

    摘要： A fuel inlet opens at one end between a valve seat and an inner surface of a valve housing on which a globe valve slides. The other end of the fuel inlet opens to an external surface of the valve housing. The fuel inlet runs almost in the direction of a central axis of the globe valve so as to prevent the formation of vortex flow around the globe valve. A spiral member is pressure fitted inside the valve housing immediately downstream of the valve seat with the spiral member being formed as a rod with a spiral fuel groove to swirl the fuel along the groove. An outlet orifice for fuel metering is formed immediately downstream of and as near as possible to the spiral member.
