Abstract
A back-gap controlling apparatus for compressor is proposed to reduce an initial torque for the motor of a compressor. A high pressure between the two scroll units of the compressor can temporarily separate the two scroll units. The casing pro se or a sealing buffer can be used to limit a displacement amount of the scroll unit The excessive displacement of scroll unit can be prevented to enhance lifetime of motor.
