1. A device for controlling a refrigerant in a refrigerant circuit including at least one compressor, at least one condenser, and at least one evaporator wherein the device is disposed between the at least one condenser and the at least one evaporator and used as an expansion device, comprising a housing with ports for the connection to fluid lines, each of which being connected via a passage opening with at least one interior volume of the housing, and at least one valve element disposed in the interior volume of the housing, and a drive element for moving the at least one valve element relative to the housing, wherein the at least one valve element is supported rotatably about an axis of rotation and comprises at least openings formed as through-bores, which openings form in the interior of the at least one valve element a common volume, wherein an axis of symmetry of a first opening and the rotational axis of the at least one valve element is located on a common axis,
wherein a second opening and a third opening of the valve element are disposed in a common center plane of the at least one valve element at an angle with respect to one another differing from 0° and from 180°, wherein the center plane is oriented orthogonally to the rotational axis of the at least one valve element, and
wherein on the surface of the at least one valve element, starting at an edge of the third opening, at least one groove is formed which extends along the center plane of the at least one valve element;
wherein the through-bores have identical diameters that are constant over their length.
