ABSTRACT:
A sealed electric compressor for use in, for example, an electric refrigerator, generates a little noise and can feed any moving part of its compressing element with refrigerator lubricant. An oil pickup tube is joined by insertion to the lowermost end of a crank shaft and includes a first centrifugal pumping portion and a second centrifugal pumping portion provided continuously and arranged at a smaller angle than that of the first centrifugal pumping portion. The second centrifugal pumping portion arranged at a smaller angle can spin in a pool of the refrigerator lubricant.
