PCT No. PCT/SE86/00125 Sec. 371 Date Nov. 12, 1986 Sec. 102(e) Date Nov. 12, 1986 PCT Filed Mar. 21, 1986 PCT Pub. No. WO86/05556 PCT Pub. Date Sep. 25, 1986.A screw compressor lubrication channel for lubrication of a rotor bearing on the compressor's low pressure side, which is supplied with refrigerant droplets containing oil accompanying the inlet gas. This kind of lubrication is usually carried out by permitting a limited amount of gas and oil to flow from the high pressure side to the low pressure side via the bearings located on the low pressure side, and further to the inlet. By this working mode compressor capacity as well as compression work deposited is lost. This is avoided when the compressor according to the present invention is provided with a special, smaller inlet channel (7), which via the rotor bearing (3) opens out in a specific inlet port (8) located at an expanding rotor thread presenting a lower pressure than the inlet (6) pressure of the compressor. |
