ABSTRACT:
A projection of an upper bearing member is provided with a porous member, and a lower space between a rotational motor and a compression mechanism is defined into a lower compression mechanism-side space and a lower rotational motor-side space. With this structure, stirring effect of working fluid flowing in the lower compression mechanism-side space caused by rotation of the rotor is suppressed, and oil drops mixed in the working fluid are prevented from being finely divided by the stirring effect, the oil drops are allowed to fall due to the gravity in the lower compression mechanism-side space, and oil separating effect from the working fluid is enhanced.
