Twin screw compressors are known. The rolling bearings of such compressors used in refrigeration systems are however often contaminated with the cooling medium e.g. freon. This results in poor lubrication and short bearing life. This problem is solved by using a bearing type which ensures the fluid film formation even with contaminated lubricant or the cooling medium (freon) as a lubricant. The bearing type capable of building up a lubricant film under such conditions is the hydrostatic bearing (Fig. 2, parts 107 - 112). This specific bearing type can work by means of hydraulic pressure supplied by an (external) liquid pump. A fluid film separating the two sliding surfaces and enabling the carrying fluid or loading conditions is quaranted by this arrangement. |
