Which type of compressor uses an orbital motion roller to compress gas?

• A. Scroll compressor
• B. Rotary compressor
• C. Reciprocating compressor
• D. Centifugal compressor

Answer: (B)

The rotary compressor utilizes an orbital motion roller to compress gas by continuously drawing in gas and compressing it as it travels through the compressor unit. This type of compressor typically features a rolling mechanism where an eccentric motion creates a change in volume, allowing for efficient gas compression. The design of the rotary compressor often results in smoother operation and quieter performance compared to some other types of compressors. In contrast, scroll compressors rely on two spiral-shaped elements that compress gas through their overlapping motion, reciprocating compressors use a piston moving back and forth to compress gas, and centrifugal compressors utilize a rotating impeller to impart velocity to the gas, which is then converted to pressure. Therefore, the unique mechanism of an orbital motion roller in a rotary compressor distinguishes it from these other compressor types.
