Abstract
In a compressor of the present invention, an intermediate pressure port through which a first discharge chamber and a motor chamber communicate with each other is formed in a front housing. A refrigerant having an intermediate pressure is discharged to the first discharge chamber. Consequently, it is possible to guide the refrigerant having the intermediate pressure in the first discharge chamber to the motor chamber, and cool an electric motor, which generates heat during actuation, with the refrigerant having the intermediate pressure. In the compressor, a first impeller and a second impeller are disposed such that large diameter portions of the first impeller and the second impeller face each other. The second impeller is smaller in diameter than the first impeller.
