Screw compressor
A valve (92) provided in line system of a lubricant supply is controlled by difference in pressure between pressure in outlet channel of compressor housing (40) and reference pressure influenced by pressure in refrigerant circuit. The valve is closed when screw rotors (44,46) are compressing refrige...

| description | A valve (92) provided in line system of a lubricant supply is controlled by difference in pressure between pressure in outlet channel of compressor housing (40) and reference pressure influenced by pressure in refrigerant circuit. The valve is closed when screw rotors (44,46) are compressing refrigerant, and closed when rotors are not compressing refrigerant. A lubricant supply conveys lubricant from a lubricant reservoir acted upon by pressure via the line system ,to the screw rotor during operation. The compressor housing includes screw rotor receiving bores (42), an inlet channel (70) and the outlet channel for refrigerant to be compressed. The screw rotors are arranged in the screw rotor receiving bores. |
