Abstract
A Method for controlling the liquid injection of a compressor device or expander device. This compressor device includes at least one compressor element or expander element, whereby the element comprises a housing that comprises a rotor chamber in which at least one rotor is rotatably affixed by means of bearings, whereby liquid is injected into the element. The method comprises the step of providing two independent separated liquid supplies to the element, whereby one liquid supply is injected into the rotor chamber and the other liquid supply is injected at the location of the bearings. The separated liquid supplies are realised by means of a modular channelling piece of an injection module.
