A valve member (6) which opens the valve in the direction of flow of the fuel and is rotatably mounted by means of a ball bearing (14), has passage portions (21b), tangential to a circle (K) concentric with the valve axis, whose outlet ports (22) are covered by the valve body (3) in the rest position. When the valve is opened by fuel pressure, the outlet ports (22) emerge from the bore (5), and the discharge of fuel causes the valve member to rotate, whereby the emerging fuel describes a helical spraying pattern. <IMAGE> |
