Translating Gear Compressor

Compressors consume 30%~40% electricity globally. Any Improvement for compressor is meaningful to our environment. We dedicate to make a new kind of compressor that is more efficient, low cost, quiet and flow adjustable.

Our compressor uses an orbital(or translating) rotor. Without reciprocal motion it runs fast and quiet. The orbital motion has a very low friction speed, so this compressor can ran much fast and its size can be reduced remarkably.

Unlike the screw and scroll compressor which have constant compression ratio and not so efficient at variable real status, our compressor uses reed valves to ensure it always output the needed pressure.

Adjustable flow makes it possible to save energy at variable load.

Efficient sealing design makes it work efficiently.

The compression structure is self-engaged without extra anti-rotate parts, so it has smaller number of parts than scroll compressor.

Its simple and strong structure make it reliable and easy to be manufactured.



Novel Working Principle

As shown in picture and video, this new compressor works different as all other styles. During the rotor translating circularly, the rotor teeth and shell teeth are engaged and form closed spaces which volume change is used to apply pressure to the gas inside.

With bypass slot for each compression chamber, the flow regulating plate can change the flow rate by simply rotating operation.



Update 1: First Miniature Air Compressor Prototype Works Well

To reduce the cost, the first prototype was designed as a small air compressor.

Our next step is to build a regular size one for detailed performances and lifetime test.



Applications

All the applications with compressors, vacuum pumps etc. Such as air/natural gas processing and pressurizing, refrigeration and air conditioning, plant product line etc. Applications have covered most industries in the world.

Oil free air compressor, for medical application

Market

There are over 100 million compressors produced every year in the world.
