Nozzle module for an injection valve and injection valve
Abstract:
A nozzle module for an injection valve has a nozzle body with a nozzle body opening extending in the direction of a longitudinal axis, and which can be hydraulically coupled to a fluid feed; a nozzle needle which is movable axially in the nozzle body opening and which in a closed position prevents a flow of fluid through at least one injection opening and otherwise releases the fluid flow; and an induction-heated heating element disposed between the nozzle body and the nozzle needle. The heating element is at least partially spaced a distance away from the nozzle body and from the nozzle needle, and during operation of the injection valve the fluid can flow against a side of the heating element facing the nozzle body and a side of the heating element facing the nozzle needle.
