Valve assembly for an injection valve and injection valve

An injection valve, comprising:

• an electromagnetic actuator unit including an armature;
• and
• a valve assembly operably coupled to the actuator unit, comprising:
• a valve body with a central longitudinal axis comprising a cavity with a fluid inlet portion and a fluid outlet portion,
• a retaining element disposed in the cavity,
• a valve needle axially moveable 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, the valve needle being fixedly connected to the retaining element which extends in a radial direction and is arranged in an axial region of the valve needle facing away from the fluid outlet portion, and
• a conical spring arranged around the central longitudinal axis between the retaining element and a top side of the armature facing the retaining element, biasing the armature away from the retaining element,
• wherein the armature of the electromagnetic actuator unit is axially movable in the cavity, the armature comprising a central axial opening through which the valve needle extends, the armature being able to slide on the valve needle and acting on the needle by way of the retaining element.
