The invention concerns a control device for load-dependent distribution of the lubricant and coolant in rotary-screw compressors with no-pump liquid injection. In order to create a control device of simple design which ensures that sufficient lubricant and coolant is supplied to the compressor's working chamber as soon as the compressor starts up, with minimum losses, it is proposed that the closing means be a valve (10) connected to a control means. This valve is located in at least one injection hole (7) branching off from the injection line (6) and ending in the intake area (4) of the working chamber (3); when the compressor has come up to full load, the valve keeps the injection hole (7) closed. <IMAGE>
