An expansion valve for at least one of an air conditioning system, a battery cooler, and an oil cooler of a motor vehicle is disclosed. The expansion valve includes a housing, a sensor, a stepping motor or a brushless DC (BLDC) motor, a valve seat, and a valve body interacting with the valve seat. The stepping motor or the BLDC motor includes a rotor and a stator surrounding the rotor. The rotor includes a shaft and a permanent magnet body that is connected to the shaft in a rotationally fixed manner. The sensor is structured and arranged to detect at least one of an axial position and an angle of rotation of the permanent magnet body.

A preheating device for an internal combustion engine may include an inlet connection for connecting a distributor rail of a fuel injection system and an outlet connection for connecting a fuel injector of the fuel injection system. A preheating chamber may be fluidically connected with the inlet connection and the outlet connection and be flowable through by a fuel flow. At least one electrical heating element may be included for heating the fuel flow in the preheating chamber. At least one metallic heating body, which may be exposed to the fuel flow in the preheating chamber, may receive the at least one heating element.
