Abstract
A method of ensuring adequate oil thickness for the bearings in a sealed compressor 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 is opened to reduce the load on the bearings.
