Abstract
An expansion valve (1) comprising an inlet opening (2) and a distributor (4) being arranged to distribute fluid medium received from the inlet opening to at least two parallel flow paths (3). At least two outlet openings (3) are adapted to deliver fluid in an at least partially gaseous state, and each outlet opening is fluidly connected to one of the parallel flow paths. A first valve part (7) and a second valve part (5) are arranged movably relative to each other in such a manner that the mutual position of the first valve part and the second valve part determines the opening degree of the expansion valve. Since the distributor (4) forms part of the expansion valve, it distributes the fluid medium to the parallel flow paths prior to or during expansion of the fluid medium, i.e. while the fluid medium is in a substantially liquid state. This makes it easier to control the distribution of fluid medium to the parallel flow paths in a uniform manner.
