Abstract: A valve (4) for a refrigeration system. Comprises two diaphragms (8, 10) being operatively connected. One diaphragm (8) is in contact with the refrigerant, the other (10) is in contact with the filling fluid. The two diaphragms (8, 10) may have different active areas. In combination with the connection between the two diaphragms (8, 10) this provides a `pressure gearing' between the filling fluid and the refrigerant. Allows the pressure of the filling fluid to be relatively low even when the pressure of the refrigerant is high, while ensuring that the valve (4) can function properly. Particularly suitable for high pressure refrigeration systems, such as CO2 systems.

Abstract: An expansion valve (1) comprising an inlet opening and at least two outlet openings (5) is disclosed. The inlet opening is adapted to receive fluid medium in a liquid state, and the outlet openings (5) are adapted to deliver fluid medium in an at least partly gaseous state. The expansion valve (1) further comprises a diaphragm (6), and at least two valve seats (4), each valve seat (4) being fluidly connected to one of the outlet openings (5). Each of the valve seats (4) forms a valve in combination with the diaphragm (6), the position of the diaphragm (6) thereby simultaneously defining an opening degree of each of the valves. A well defined distribution of fluid flow towards each of the outlet openings (5) is easily defined by movements of the diaphragm (6). The distribution takes place before or during expansion of the fluid medium. The expansion valve (1) may be arranged in an refrigerant path of a refrigeration system.
