Abstract
A device for expansion of coolant having a housing with a flow channel. A ball-shaped valve element arranged to be integrated inside the housing. The valve element is mounted so that it can turn about an axis of rotation and is configured with a through channel. The through channel of the valve element is configured with an entry opening and an exit opening and arranged so that the flow cross section of the through channel decreases from the entry opening to the exit opening in the direction of flow of the coolant. At the exit of the through channel the least flow cross section is formed.
