Zusammenfassung:	PURPOSE:With the above captioned jet valve to inject fuel pulsatively with application of spherical valve, to improve both fuel jet volume control and atomizing efficiency at initiation of fuel injection by furnishing swirling device to organize fuel swirling stream on downstream of valve seat. CONSTITUTION:Screw grooved element 24 with fuel swirling fuel groove 24 is pressed in the valve housing at downstream directly under valve seat 4 of which immediate understream portion is formed to outlet orifice 23 to measure volume of fuel. With this device, fuel supplied through fuel inlet 21 does not swirl when it is passing through valve seat 4, thus enabling to prevent increase of valve stroke. Accordingly, it is possible to reduce the time required for the valve to arrive at its stabilized condition after starting to stroke, or the time required for the fuel stream becomes to be settled for the control after it commenced to flow. Therefore, the control can be arranged at the point of short pulse width of exciting current applied on coil 19, in other words at the point where flow rate is small.
