PCT No. PCT/DE94/01386 Sec. 371 Date Aug. 1, 1995 Sec. 102(e) Date Aug. 1, 1995 PCT Filed Nov. 24, 1994 PCT Pub. No. WO95/15435 PCT Pub. Date Jun. 8, 1995A fuel injection nozzle for preinjection and main injection has a nozzle holder in which two closing springs are arranged coaxially, one spring acts continuously on the valve needle via a central pressure bolt and the other spring acts on the valve needle, via a pressure ring surrounding the pressure bolt, once the valve needle has passed through a pretravel (hv). Between the valve needle and the pressure bolt and the pressure ring, an intermediate pressure element which is constructed as a disk is arranged, the outer edge area of the intermediate pressure element does not come into contact with the pressure ring until after the valve needle has passed through the pretravel (hv), which pressure is supported in the closed position of the valve needle by a shoulder of an intermediate disk. In order to prevent the connection between the low pressure space at the valve needle and the pressure-relieved spring chamber being interrupted in the pretravel position when the intermediate pressure element comes into axial contact with the pressure ring which is supported on the shoulder of the intermediate disk, bridging channels are arranged at least in the intermediate pressure element.
