Abstract
An electric expansion valve () including a valve housing (), a valve seat (), a valve element () cooperating with the valve seat (), a drive driving the valve element () and including a rotary motor () having an axis () of rotation. The valve element () is connected to the motor () and has a possibility of radial displacement between the rotor () and the valve element () with respect to the axis () of rotation. Such an expansion valve should ensure a long lifetime with low production costs. To this end the valve element () is connected to the motor () by means of a fixing element () which guarantees a defined position of the valve element () in axial direction while allowing the radial displacement between the axis () of rotation and the valve element ().
