Patent ID: 8087598

Claim:
A nozzle module for an injection valve, comprising a nozzle body, which has a nozzle body recess with a wall, wherein the nozzle body recess can be hydraulically coupled to a high pressure circuit of a fluid, a seal seat formed on the wall of the nozzle body recess, at least one nozzle needle arranged in an axially moveable fashion in the nozzle body recess with a central axis, wherein the nozzle needle comprises a seat area with a sealing surface and the sealing surface interacts with the seal seat such that in a closed position the nozzle needle prevents fluid from flowing through the nozzle module and in an open position releases a fluid flow through the nozzle module, wherein the nozzle needle comprises a supporting area, which is arranged radially outside and axially at a distance from the seat area and which is operable to support the nozzle needle against the wall of the nozzle body recess when the nozzle needle is in the closed position, and which is spaced apart from the wall of the nozzle body recess when the nozzle needle is in the open position to allow fluid passage between the supporting area and the wall of the nozzle body recess, wherein the nozzle needle comprises at least one nozzle needle recess embodied as a through-channel in the supporting area, the at least one nozzle needle recess being arranged and embodied such that when the supporting area abuts the wall of the nozzle body recess, an area of the nozzle body recess, which axially faces away from the seat area in respect of the supporting area, is hydraulically coupled to an area of the nozzle body recess which axially faces the seat area in respect of the supporting area; and wherein the supporting area and the seat area of the nozzle needle are non-movably connected with respect to each other.
