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.
