ABSTRACT:
Formed in a scroll type compression mechanism is a connection passageway with a discharge opening through which refrigerant compressed by the compression mechanism flows out into a clearance space defined between the compression mechanism and a drive motor. A muffler space in communication with the connection passageway that is configured to reduce operating noise is formed in the compression mechanism. A motor cooling passageway configured to circulate working fluid which has flowed out into the clearance space is formed between the drive motor and an inner surface area of a casing. A guide plate is disposed in the clearance space. Formed in the guide plate is a flow dividing concave portion which causes a part of refrigerant flowing toward the motor cooling passageway to be distributed in a circumferential direction and toward an internal end of a discharge pipe located in the clearance space.
