A compressor device comprising:
- a screw compressor with a compression chamber that is formed by a compression housing, in which a pair of meshed compressor rotors in the form of a screw are rotatably mounted;
- a drive motor that is provided with a motor chamber formed by a motor housing, in which a motor shaft is rotatably mounted that drives at least one of the aforementioned two compressor rotors;
- an inlet to the screw compressor for the supply of air;
- an outlet to the screw compressor for the discharge of compressed air, and which is connected to a pressure vessel via an outlet pipe;
- an air outlet on the pressure vessel for the supply of compressed air from the pressure vessel to a consumer;
- a control system for controlling one or more liquid or gas flows in the compressor device;
- said control system being provided with:
- an inlet valve on the inlet of the screw compressor;
- and,
- a tap or valve to close and open the air outlet of the pressure vessel;
- wherein the compression housing and the motor housing are connected directly to one another to form a compressor housing, whereby the motor chamber and the compression chamber are not sealed off from one another and whereby the outlet pipe between the pressure vessel and the screw compressor is free of closing means in order to enable a flow through the outlet pipe in both directions.
