Abstract

An injection valve may have a nozzle body with a longitudinal axis, in which a nozzle body aperture and at least one injection opening are arranged, wherein the nozzle body aperture can be coupled hydraulically to a high-pressure circuit for a fluid, at least one nozzle needle arranged in an axially movable manner in the nozzle body aperture, wherein the nozzle needle prevents fluid flow through the at least one injection opening in a closing position and allows fluid flow through the at least one injection opening outside the closing position, an actuator housing, which is designed to accommodate an actuator designed to act on the nozzle needle, and at least one fluid line, which is designed for hydraulic coupling to the high-pressure circuit for the fluid and is constructed and arranged separately from the actuator housing, and is directly coupled hydraulically to the nozzle body aperture.
