Patent ID: 8256691

Claim:
A nozzle module for an injection valve, comprising: a nozzle body formed with a nozzle body opening extending in a direction of a longitudinal axis and configured for hydraulic coupling with a fluid feed; a nozzle needle disposed to be movable in an axial direction in said nozzle body opening and configured to prevent a fluid flow through at least one injection opening in a closed position and otherwise to release the fluid flow; and an inductively heated heating element having opposed elongated heating surfaces disposed between said nozzle body and said nozzle needle, said heating surfaces of said heating element being at least partially spaced at a spacing distance from said nozzle body and from said nozzle needle, such that, during an operation of the injection valve, fluid flows against a surface of said heating element facing said nozzle body and against a surface of said heating element facing said nozzle needle, and said opposed elongated surfaces of said heating element being a zigzag configuration having said opposed elongated surfaces extending in the axial direction defining a folded path between said nozzle body and said nozzle needle in the shape of a hollow cylinder extending in the axial direction.
