Abstract: A device for controlling a flow rate and expanding a refrigerant in a refrigerant circuit of an air conditioning system of a motor vehicle. The device has a housing, an actuating element and a valve element arranged in the interior of the housing and aligned in an axial direction, a valve seat element, and at least one sealing element. The valve element is arranged within the valve seat element and sealed towards the housing and the valve seat element via the at least one sealing element, and is formed in a circular cylindrical shape with a sealing area formed on a lateral surface. The inner surface of the sealing element forms a sealing seat in conjunction with the sealing area of the valve element.
