Abstract
An expansion valve for an air conditioning system of a motor vehicle may include a housing, a sensor, a stepping motor or a BLDC motor, a valve seat, and a valve body. The stepping motor or the BLDC motor may include a rotor and a stator surrounding the rotor. The rotor may include a permanent magnet body connected non-rotatably therewith. A separating can may be provided that surrounds the rotor and separates a wet region on a rotor side from a dry region on a stator side. The sensor may be connected with the separating can via an adhesive layer formed as a heat-conductive layer.
