Patent ID: 7393191

Claim:
A scroll compressor in which an interior of a closed vessel is divided into a compression chamber on an upper side, which has a refrigerant compressing section, and a motor chamber on a lower side, which has a motor and is included in a part of a circulating path for refrigerant gas, by a main frame; in said motor chamber, there are provided, as means for causing a motor upper space to communicate with a motor lower space, first communicating means formed on an outer periphery side of a stator of said motor and second communicating means formed on a rotor side of said motor or on a rotor rotating shaft side; and a radial fan and a balancer that rotate together with said rotor are provided on an upper end side of said rotor, so that some of said refrigerant gas is sucked from said motor lower space via said second communicating means, and is discharged into said motor upper space so as to be circulated in said closed vessel by said radial fan, wherein said radial fan has a plurality of blades formed radially in a range of approximately 180° opposed to said balancer so as to have a height smaller than a height of said balancer, and a fan cap including a fan cover portion covering top faces of said blades and an engagement portion fixed to the upper end side of said rotor.
