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.
A compressor comprising a compression mechanism for compressing working fluid, a rotational motor including a stator, a rotor for driving said compression mechanism and a container for accommodating said compression mechanism and said rotational motor, in which the compressed working fluid flows from said compression mechanism to said rotational motor, wherein a space between said compression mechanism and said rotational motor is defined by a porous member.
A compressor comprising a compression mechanism for compressing working fluid, a rotational motor including a stator, a rotor for driving said compression mechanism and a container for accommodating said compression mechanism and said rotational motor, in which said container includes a discharge pipe on the opposite side of said compression mechanism with respect to said rotational motor, and the compressed working fluid flows from said rotational motor to said discharge pipe, wherein a space between said rotational motor and said discharge pipe is defined by a porous member.
