Abstract: A current coil for use in a needle motion sensor for a fuel injection valve, having a coil body, which is provided with a metallic coil core, wherein connecting contact wires for the coil winding are held pressed against the coil body in formed grooves of the coil body.

Abstract: A current coil is proposed, in particular for use in a needle motion sensor for a fuel injection valve, having a coil body (1), which is provided with a metallic coil core (3), wherein connecting contact wires (13) for the coil winding (7) are held pressed against the coil body in formed grooves (15) of the coil body.

Abstract: An injection nozzle provided with an inductive needle movement sensor is constructed in such a way that a coil winding of the sensor is faultlessly sealed against overflow oil without more space being required for the needle movement sensor than is required in a construction without a sealing of the coil winding against overflow oil. For this purpose, a coil core of the induction coil is lengthened into a lengthened portion of the chamber in a short-circuit body of the sensor, which chamber receives an induction coil, and a sealing ring seals the coil winding against a guide gap of the magneto armature in the short-circuit body. An annular gap between the short-circuit body and a bore hole wall in a nozzle holder receiving is sealed by means of a sealing ring. A clamping flange connected with the coil core directly contacts an adjacent annular flange of the coil body and the coil winding contacts connection wires on the other side of a clamping flange.
