Abstract

An injection system for diesel engines with a nozzle holder (1), the pressure channel (2) of which is connected on one side to the injection pump and on the other, comprises a nozzle body (3) secured to the nozzle holder (1) by a tensioning nut (10). To provide a seal, there is an intermediate disc (13) between the nozzle holder (1) and the nozzle body (3). To seal the high-pressure connection in the region of the pressure channels (2, 4) there is a deformable metal seal which bears on a sealing surface and is fitted in a conical seat (19) in the region of the outlet of the pressure channel (2) of the nozzle holder (1).
