Structural study on a swing compressor with no valves for air compression

Abstract

This paper presents a novel swing compressor with no valves employed in air compression. The design and work principle of this swing compressor are introduced. And the effects of discharge port, exhaust cavity, and crank speed on the performances of this compressor are analyzed. Under the same operating conditions and dimensions, the size of exhaust cavity mainly depends on the discharge port width. Additionally, the exhaust cavity angle has a direct impact on the compression process, whether it is over-compression or under-compression. And the over-compression loss can be designed below 2%. Overall, the assessment of the structure shows that this novel swing compressor with no valves has the advantages of simple component geometries, light weight, and high efficiency, which makes it well suited to the requirements of air compression.
