Abstract
An expansion valve for a vapor compression system comprises a first valve member and a second valve member. The first valve member and the second valve member are arranged movably relative to each other, and the relative position of the first valve member and the second valve member determines an opening degree of the expansion valve. The first valve member and/or the second valve member is/are automatically movable in response to changes in a differential pressure across the expansion valve, the opening degree of the expansion valve thereby being automatically altered in response to changes in the differential pressure across the expansion valve. It is ensured that the opening degree of the expansion valve is automatically adjusted to the actual operating conditions, thereby optimising the efficiency of the vapour compression system.
