ABSTRACT:
A sealed case has first and second housing portions. A motor section is arranged in the first housing portion of the sealed case and has a rotating shaft extending toward the second housing portion. A compression section has first and second compression mechanisms stacked in the second housing portion of the sealed case and driven by the rotating shaft. A first valve cover has a predetermined volume so as to temporarily store a high-pressure fluid discharged from the first compression mechanism near the motor section. A second valve cover has a predetermined volume larger than that of the first valve cover so as to temporarily store a high-pressure fluid discharged from the second compression mechanism opposite to the motor section.
