Abstract

The present invention relates to an electromotive compressor comprising: a pair of compressor housings (7, 8) not only providing suction ports (26) in each of the center means thereof, but also an annular diffuser means (27) surrounding these suction ports (26) as well as a scrolling means (28), in addition to said suction port (26) being symmetrically disposed so as to face in opposite directions; and an electric motor (3) disposed between this pair of compressor housings (7, 8); and a pair of impellers (21, 22) attached symmetrically so as to face in mutually opposite directions on both terminal means of the revolving axis (17) of this electric motor (3); and a symmetrically configured exit tube (4) extending in a substantially U shape so as to mutually meet the exits of the scroll means (28) of the above described pair of compressor housings (7, 8), in addition to having a single spew port (5) in the center thereof.
