  • Scroll compressor capable of effectively cooling motor thereof
    Patent number: 5624243
    Abstract: A discharge passage 15 which communicates with a discharge outlet 16 of a compressing section 3 and discharges compressed gas into a chamber S1 opposite to the compressing section with respect to a motor 2 is provided axially through a drive shaft 4 of the motor 2. An outward discharge pipe 17 is opened at a middle chamber S2 provided between the compressing section 3 and the motor 2 inside a hermetic casing 1. An effect of cooling the motor 2 by discharge gas can be fully exerted, so that possible temperature increase of the motor 2 is prevented to improve reliability and efficiency of the motor 2, and oil mixed in the discharge gas is separated.
