Abstract: Valve (1), in particular expansion valve, is described including a valve element driven by an actuator and being arranged in a valve housing arrangement (4, 5, 15), wherein the valve housing arrangement (4, 5, 15) includes a housing (4), a tube (15) connected to the housing (4) and at least one connector (5) extending from the housing (4), wherein the actuator comprises a rotary motor having a stator and a rotor, the rotor being arranged inside the tube (15) and the stator being arranged outside the tube (15). A simple way is needed to position the stator and the rotor relative to each other. To this end the stator is fixed to a stator holder (16) which is arranged around the tube (15) and connected to the housing arrangement (4, 5, 15).

Abstract: Electric expansion valve (1) including a valve housing (12), a valve seat (2), a valve element (3) cooperating with the valve seat (2), a drive driving the valve element (3) and including a rotary motor (4) having an axis (17) of rotation. The valve element (3) is connected to the motor (4) and has a possibility of radial displacement between the rotor (6) and the valve element (3) with respect to the axis (17) of rotation. Such an expansion valve should ensure a long lifetime with low production costs. To this end the valve element (3) is connected to the motor (4) by means of a fixing element (16) which guarantees a defined position of the valve element (3) in axial direction while allowing the radial displacement between the axis (17) of rotation and the valve element (3).
