<p>A method of ensuring adequate oil thickness for the bearings (28, 30) in a sealed compressor (28, 30) includes the step of monitoring the viscosity of a lubricant for the bearings. If the monitored viscosity drops below a minimum, then some control is effected to reduce the necessary bearing film thickness. In a preferred embodiment, an unloader valve (40) is opened to reduce the load on the bearings (28, 30). <IMAGE></p> |
