Abstract:
A nozzle module for an injection valve has a nozzle body with a recess with a wall, being operable to hydraulically couple the recess to a high pressure fluid circuit, a seal seat embodied on the wall, at least one nozzle needle arranged in an axially moveable fashion in the recess. The needle has a seat area with a sealing surface interacting with the seal seat to open and close the valve, respectively, and a supporting area, arranged radially outside and axially at a distance from the seat area and supporting the needle against the wall when the needle closes. The needle has at least one needle recess, which when the supporting area rests against the wall of the body recess, an area of the body recess facing axially away from the seat area is hydraulically coupled to an area of the body recess which axially faces the seat area.
