Valve assembly for an injection valve, with - a valve body including a central longitudinal axis, the valve body comprising a cavity with a fluid inlet portion and a fluid outlet portion, - a valve needle axially movable in the cavity, the valve needle preventing a fluid flow through the fluid outlet portion in a closing position and releasing the fluid flow through the fluid outlet portion in further positions, - a main spring arranged and designed to act on the valve needle to move the valve needle in the axial direction toward its closing position, - an electro-magnetic actuator unit being designed to actuate the valve needle, the actuator unit comprising an armature which is arranged in the cavity and is axially moveable relative to the valve needle, and - a block-shaped stop element being arranged in the cavity axially adjacent to the armature and being fixedly coupled to the valve body in such fashion that a gap can occur between the armature and the stop element, the stop element being designed directly to limit the axial movement of the armature, wherein - the valve assembly comprises a guide being arranged in the cavity and being fixedly coupled to the valve needle, - the armature is designed and arranged to come in contact with the guide when the valve needle is actuated to leave the closing position and to mechanically decouple from the guide and to move towards the stop element due to its inertia when the valve needle reaches the closing position, - an armature spring is arranged in the cavity and is coupled to the armature axially adjacent to the armature, - the armature has a plane surface facing the fluid outlet portion, and the block-shaped stop element has a plane surface facing the plane surface of the armature, and the plane surface of the armature is coupleable to the plane surface of the stop element by adhesion caused by a sticking effect due to a thin layer of fluid which is located in said gap between the plane surface of the armature and the plane surface of the stop element thereby damping a movement of the armature towards the fluid inlet portion characterized in that the armature spring is arranged to provide a force to the armature for contributing to coupling the armature with the valve needle and forcing the armature towards the guide. - a valve body including a central longitudinal axis, the valve body comprising a cavity with a fluid inlet portion and a fluid outlet portion, - a valve needle axially movable in the cavity, the valve needle preventing a fluid flow through the fluid outlet portion in a closing position and releasing the fluid flow through the fluid outlet portion in further positions, - a main spring arranged and designed to act on the valve needle to move the valve needle in the axial direction toward its closing position, - an electro-magnetic actuator unit being designed to actuate the valve needle, the actuator unit comprising an armature which is arranged in the cavity and is axially moveable relative to the valve needle, and - a block-shaped stop element being arranged in the cavity axially adjacent to the armature and being fixedly coupled to the valve body in such fashion that a gap can occur between the armature and the stop element, the stop element being designed directly to limit the axial movement of the armature, - the valve assembly comprises a guide being arranged in the cavity and being fixedly coupled to the valve needle, - the armature is designed and arranged to come in contact with the guide when the valve needle is actuated to leave the closing position and to mechanically decouple from the guide and to move towards the stop element due to its inertia when the valve needle reaches the closing position, - an armature spring is arranged in the cavity and is coupled to the armature axially adjacent to the armature, - the armature has a plane surface facing the fluid outlet portion, and the block-shaped stop element has a plane surface facing the plane surface of the armature, and the plane surface of the armature is coupleable to the plane surface of the stop element by adhesion caused by a sticking effect due to a thin layer of fluid which is located in said gap between the plane surface of the armature and the plane surface of the stop element thereby damping a movement of the armature towards the fluid inlet portion characterized in that the armature spring is arranged to provide a force to the armature for contributing to coupling the armature with the valve needle and forcing the armature towards the guide.
