Volume between thepockets is simultaneously reduced When the pocket reaches the center, gas is now at highpressure and is forced out of a port located in the centerof the fixed scrolls During compression, several pockets are compressedsimultaneously resulting in a smooth continuouscompression cycle Continuous flank contact, maintained by centrifugalforce, minimizes gas leakage and maximizes efficiency Compressor is tolerant to the effects of slugging andcontaminants.
