Abstract: A nozzle assembly of a fuel injector extends along a main axis and includes a nozzle body provided with an inner space divided in upstream chamber and downstream chamber and also with, a valve needle including a main elongated shaft slidably guided in said inner space and extending through-out both upstream and downstream chambers. The nozzle body and the valve needle cooperate to define throttle fluid communication means between upstream and downstream chambers inducing, in use, a pressure drop when fuel flows through. The nozzle assembly is further provided with a tubular sleeve arranged between the upstream chamber and the downstream chamber in abutment against a face of the body and being radially self-centred guided by a cylindrical face of the needle, the throttle means being arranged in said sleeve.

Abstract: An injection device for administering a reagent into an exhaust passage of an internal combustion engine, the injection device having an axis along its length and comprising an outwardly opening valve member having a seating surface which is engageable with a valve seating region. A seating member provided with an internal bore which defines the valve seating region, wherein the internal bore further defines a flow re-directing region downstream of the valve seating region. The seating member has an end face provided with a feature which intersects with at least a portion of the flow re-directing region to define, together with the flow re-directing region, a spray path for reagent exiting the injection device when the valve member is moved outwardly from the bore away from the valve seating region. The spray path has a variable spray angle, relative to the axis, around the circumference of the valve seating region.
