Valve device, in particular for a refrigerating machine

摘要

The invention relates to a valve device for a refrigerating machine that circulates a refrigerant, include at least one condenser and at least one evaporator. The valve device comprises at least one inlet, at which the refrigerant in the condenser can be fed to the valve device, at least three outlets, through which the refrigerant in the valve device can be discharged into the evaporator, and a valve element, which is rotatably arranged about an axis and can be brought into a plurality of positions. In a first position, the first outlet is connected to the inlet in order to convey refrigerant. In a second position, the second outlet is connected to the inlet in order to convey refrigerant. In a third position, the third outlet is connected to the inlet in order to convey refrigerant.
