Abstract: A method for controlling a compressor device (1) with a compressor element (2) and oil circuit (14) with oil (15) that is injected into the compressor element (2) by a fan (19) via a cooler (18), with a bypass pipe (20) across the cooler (18), whereby when the temperature (T) of the compressor element (2) is less than a value (Tset), the method including the following steps: switching the fan (19) off; when the temperature (T) is still less than Tset, driving the oil (15) via the bypass pipe (20); when the temperature (T) is still less than Tset, decreasing the quantity of oil (15) that is injected into the compressor element (2) until the temperature (T) is equal to Tset

Abstract: An inlet valve that includes a pipe and a housing that forms a chamber around this pipe, in which an aperture is affixed with blades that are slidingly provided in the housing. Whereby these blades present a protruding section with edges that lie against one another and whereby the blades are provided with a spindle and there are means to enable the blades to pivot around these spindles, during the movement of the spindles, between a closed position, whereby the sections are oriented radially to close off the passage in the pipe, and an open position whereby the sections are turned away from the pipe.
