Abstract: A device for controlling a flow rate and expanding a fluid in a fluid circuit. The device is formed with an enclosure and a valve element arranged inside the enclosure. The valve element which is arranged movably in a linear movement in the direction of a longitudinal axis relative to the enclosure has a sealing surface and a control area formed at a first end face of the valve element and arranged adjacent to the sealing surface in the axial direction. The sealing surface is formed as a lateral surface of a straight circular cylinder with a constant outer diameter. An outer diameter of a surface of the control area corresponds to the outer diameter of the sealing surface. The control area has throughflow apertures and at least one control aperture. The valve element in the control area is formed with a substantially hollow circular cylindrical-shaped wall.
