摘要
Liquid injected screw compressor with an inlet valve and blow-off valve; a liquid circuit with injector; a controller for the transition from unloaded to loaded, whereby when unloaded the inlet valve is closed and the blow-off valve is open, and when loaded the inlet valve is open and the blow-off valve is closed, and whereby during an aforementioned transition, when the injection pressure is below a minimum threshold, the inlet valve remains closed and is opened with a certain delay and that there are means to gradually increase the injection during this delay and to open the inlet valve when the injection pressure has reached the minimum threshold.
