| description | In order to improve a screw compressor for compressing refrigerant in a refrigerant circuit, comprising a compressor housing, in which a screw rotor receiving means and an inlet channel as well as an outlet channel for the refrigerant to be compressed are provided, at least one screw rotor arranged in the screw rotor receiving means, a drive for the at least one screw rotor and a lubricant supply which conveys lubricant from a lubricant reservoir acted upon by pressure via a line system at least to the at least one screw rotor during operation, in such a manner that the operation and the monitoring of the screw compressor are reliable it is suggested that a valve be provided in the line system of the lubricant supply, this valve being controllable by way of a difference in pressure between the pressure in the outlet channel and a reference pressure influenced by a pressure in the refrigerant circuit and opening when the screw rotor is compressing refrigerant as well as closing when the screw rotor is not compressing refrigerant. |
