Abstract: An expansion valve operable by a stepper motor, the expansion valve including a housing; a hollow shaft arranged in the housing; a valve base that supports the hollow shaft and closes the housing; a rotor that is drivable by a stator of the stepper motor; a center spool arranged within the hollow shaft and drivable by the rotor so that a rotation of the center spool is transferrable by a threaded connection into an axial movement of the center spool that opens or closes the expansion valve; and a spiral body that includes a thread turn and that is arranged about an enveloping surface of the hollow shaft and that is drivable by the rotor, wherein a stop body is arranged at the hollow shaft and movable in the thread turn of the spiral body.

Abstract: The invention relates to a system for monitoring the position of the valve needle of an expansion valve, having an expansion valve having a valve seat; a valve needle which is configured so as to be convertible axially between a first position in which the valve needle is received by the valve seat and closes the expansion valve, and a second position in which the valve needle is axially spaced apart from the valve seat and the expansion valve is at least partially opened; wherein the expansion valve has a magnet which is fixedly assigned to the valve needle such that the magnet is axially movable conjointly with the valve needle; and has a Hall sensor, wherein the Hall sensor is fixedly assigned to the valve seat and, by means of the flux density vector of the magnet, is configured for determining directly the absolute axial position of the valve needle.
