Claim:
1. A condensing apparatus, comprising: a compressor which includes a compression part compressing a working fluid; a condenser which condenses the working fluid compressed by the compression part; and a spray mechanism including a nozzle which sprays a cooling fluid into a fluid passage to cool the working fluid flowing through the fluid passage between a discharge opening of the compression part and an inlet of the condenser, wherein: the compressor further includes an electric motor having a rotating shaft, and a velocity reducing part for reducing a flow velocity of the working fluid discharged from the discharge opening of the compression part, said velocity reducing part includes a case portion which has an outer circumferential surface portion and an inner circumferential surface portion, extending in an axial direction of the rotating shaft of the electric motor, and an end surface portion connecting downstream ends of the outer and the inner circumferential surface portions such that a space is formed in the case portion, said electrical motor in its entirety is disposed in a space formed radially inward from the inner circumferential surface portion; the space of the velocity reducing part forms a part of the fluid passage; the space is formed so as to extend in the axial direction of the rotating shaft and has a ring shape in a perpendicular section to the axial direction; and a plurality of the nozzles are arranged along a circumferential direction on the end surface portion having the ring shape and spray the cooling fluid on the working fluid flowing through the velocity reducing part.
