Document Type and Number:
Japanese Patent JP4143827
Kind Code:
B2
Abstract:
In the case where a radial fan is provided on the upper end side of a rotor to provide an air circulating flow containing refrigerant gas so as not to hinder the flow of lubricating oil in a motor chamber, by which a motor is cooled, in order to reduce the cost of the radial fan, the radial fan is constructed by combining a plurality of blades (fan blades) ( 242 ) formed radially in the range of approximately 180° opposed to an upper balancer ( 270 ) so as to have a height smaller than the height of the upper balancer ( 270 ), and a fan cap ( 260 ) including a fan cover portion ( 262 ) covering the top faces of the blades ( 242 ) and an engagement portion ( 263 ) fixed to the upper end side of the rotor.
