Abstract (en)
[origin: WO9006439A1] An injection nozzle fitted with an inductive needle movement probe (28) is to be so constructed that the coil (32) is properly sealed against oil leaks without requiring more space than a design without an oil seal for the coil (32). To this end, the core (36) of the induction coil (30) is extended into a lengthened section (107) of the chamber in the recoil body (25) enclosing the induction coil (30) in which is fitted a ring (56) sealing the coil (32) against the guide slot of the magnet armature (38) in the recoil body (25). In addition, the annular slot between the recoil body (25) and the wall of the drilling in the nozzle holder (10) enclosing it is sealed by a ring (112). The clamping flange (62) linked to the coil core (36) bears directly on the adjacent annular flange (48) of the coil body (34) and the coil (32) makes contact with the connecting wires (40, 42) on the far side of the clamping flange (62). Preferred field of application is in injection nozzles for diesel engines.
