Fuel injection nozzle holder for internal combustion engines

A fuel injection nozzle for Diesel internal combustion engines, having an induction coil including a winding attached to a housing and a reciprocable valve needle comprises a coil core, the stroke of said valve needle coil core arranged to vary the reluctance of the magnetic circuit of the induction coil and thereby generate a signal, said induction coil secured in an intermediate disc member which abuts a nozzle holder and a pressure element and said valve needle form said coil core, characterized in that first and second contact springs are embedded in said induction coil, each of said contact springs having end portions, one end portion of which springs forms a substantially tangentially extending contact tongue, and another end portion of which springs protrudes into a recess in said induction coil for connection with said winding.
