Abstract
A refrigerant compressor includes a sealed case, which contains a compression mechanism, a motor part, and an oil reservoir formed in a lower portion. An oil supply pipe links the oil reservoir and a suction side of the compression mechanism and introduces oil in the oil reservoir to the suction side. The amount of oil supply provided to the suction side is adjusted by detecting the rotational speed of the motor part, such that the amount of oil supply provided to the suction side of the oil supply pipe decreases as the rotational speed of the motor part increases.
