摘要：
This invention relates to a method and a device for intermediate cooling in an oil-injected multi-stage screw compressor. Between the outlet (14) in one stage (10) and the inlet (16) in a subsequent stage (11) a connecting passageway (15) is located, through which the gas compressed in the firstmentioned stage (10) is supplied to the subsequent stage (11). For cooling the gas flowing out from the firstmentioned stage (10), in the connecting passageway (15) at least one nozzle (19) is located for the supply of a large cooling oil amount.
