Abstract
A dosing device comprises a housing () provided with an actuator, a dosing opening (), a guiding shaft () which surrounds part of the valve needle () and forms a valve chamber () with the same, and a fluid chamber module () which is welded to the housing () in the form of a duct for guiding the valve needle () into the housing (). The fluid chamber module () and the housing () are assembled along a separation surface () which is subjected to pressure by the dosing liquid and is formed almost only by axial cylinder wall surface parts () in order to reduce the pressure load on the weld seam ().
