Abstract

The invention refers to an air-cooled compressor assembly for supplying a cryo-refrigerator with helium. The assembly includes a first cooler through which compressed helium flows, another cooler through which operating oil for the compressor flows, and a ventilator. It is suggested that the coolers for helium and oil are located in a separate housing, that the cooler for the helium is positioned upstream of the oil cooler with respect to the air stream generated by the ventilator, and that the compressor housing and the cooler housing are connected with each other via flexible lines.
