Claim Text:
1. A valve for a vapour compression system, said valve comprising: an inlet opening adapted to receive fluid medium; at least two outlet openings, each being fluidly connected to one of two or more parallel flow paths in the vapour compression system, each outlet opening being adapted to deliver fluid medium to one of the two or more parallel flow paths in the vapour compression system, the two or more parallel flow paths comprising two or more evaporators, or two or more evaporator coils of an evaporator, arranged in parallel in the vapour compression system; a first valve part having at least two flow passages formed therein, each flow passage being fluidly connected to one of the outlet openings; a second valve part having at least one primary flow passage and at least one secondary flow passage formed therein, the primary flow passage(s) and the secondary flow passage(s) being fluidly connected to the inlet opening, the first valve part and the second valve part being movable relative to each other in such a manner that the mutual position of the first valve part and the second valve part determines a fluid flow between the inlet opening and each of the outlet openings, via the flow passages of the first valve part and the second valve part; wherein each primary flow passage defines a flow rate of fluid medium which is significantly larger than a flow rate defined by each of the secondary flow passage(s); wherein each of the at least two flow passages of the first valve part is configured to be alternatingly fluidly connected to each of the at least one primary flow passage and at least one secondary flow passage of the second valve part; so that, if one of the primary flow passage(s) of the second valve part is fluidly connected to a given flow passage of the first valve part, a major part of the fluid medium received from the inlet opening is distributed to the one of the primary flow passage(s) which is fluidly connected to the given flow passage; and so that, if one of the secondary flow passage(s) of the second valve part is fluidly connected to a given flow passage of the first valve part, a minor part of the fluid medium received from the inlet opening is distributed to the one of the secondary flow passage(s) which is fluidly connected to the given flow passage.
