The invention relates to a device for regulating the flow and distribution of a fluid in a fluid circuit, in particular of a refrigerant in a refrigerant circuit. The device comprises: a housing having a connection to a fluid line, the connection being connected to the interior volume of the housing via a passage opening; and a valve element arranged in the interior volume of the housing and having an adjusting element for moving the valve element relative to the housing. The valve element is mounted so as to be rotatable about an axis of rotation and has an opening formed as a through-hole, the opening forming a common volume inside the valve element. The axis of symmetry of the at least one passage opening of the first opening, the axis of rotation of the valve element, and the axis of symmetry of the passage opening of the first connection of the housing are arranged in the z-direction, the axis of symmetry of the through-holes of the at least three openings of the valve element andthe axis of symmetry of the through-openings of the two connections of the housing are arranged in a plane expanded in two directions x, y. The directions x, y, z are each oriented perpendicular to each other.
