Abstract: The invention relates to an expansion valve (1) for high-pressure refrigeration systems with a valve seat (5), a valve element (9) cooperating with the valve seat (5), a spring arrangement, which acts upon the valve element (9), and an adjusting device (23) for the spring arrangement. It is endeavoured to provide an expansion valve, which can be driven by a relatively weak drive, also in connection with high pressures. For this purpose, the spring arrangement has at least a first spring (11) and a second spring (12), which act upon the valve element, the first spring (11) defining a operating area and the second spring (12) having a spring force, which can be changed by means of the adjusting device.

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: L'invention décrit un organe de commande (1) pourvu d'une partie supérieure (2) comprenant un système d'actionnement (5), et une partie inférieure (3) portant la partie supérieure (2), ces deux parties étant accouplées de manière séparables et le système d'actionnement entraînant un élément de commande (6). Dans un organe de commande de ce type, il est souhaitable que la partie supérieure puisse être aisément montée sur la partie inférieure et puisse en être aisément détachée. A cet effet, la partie supérieure (2) et la partie inférieure (3) sont accouplées par un joint à baïonnette (18, 16).
