abstract The invention presented here relates to an arrangement for controlling the flow of coolant fluid in compressors, in particular in rotary compressors, which comprises the following: a coolant-fluid intake for coolant fluid discharged from the compressor and a coolant-fluid output for returning the coolant fluid into the compressor, a fluid cooler through which when necessary part of the coolant fluid can be directed for cooling, wherein a system-control actuator controls the magnitude of the part of the current of cooling fluid that is directed through the fluid cooler on the basis of system parameters, in particular on the basis of the temperature of the coolant fluid, by means of a fluid-control device. In addition a summer-/winter-operation actuator is provided, which can take priority over the system-control actuator so that in a summer position it completely or partially eliminates the action of the system-control actuator, in such a way that when the summer-/winter-operation actuator is activated, the part of the coolant current that is directed through the fluid cooler is increased or reduced by a fluid-control means. (Fig. 2).
