Abstract
A hermetically sealed rotary refrigerant compressor, comprising a compression chamber, a roller eccentrically rotatable in the chamber, and a vane slidably mounted in a slot in the wall of the chamber dividing the chamber between a low pressure suction side and a high pressure compression side including means for modulating the pressure differential between the low pressure suction side and the high pressure compression side of the vane at a preselected time in the compression cycle so as to minimize the frictional forces between the vane and vane slot caused by the pressure differential in the chamber.
