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 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.
