Piston Air Compressor Based on Symmetrical Double-Crank Link Mechanism

Abstract

Machine vibration, noise and cylinder barrel wearing are produced when ordinary piston air compressor driven by crank link mechanism is working. Piston air compressor driven by double-crank link mechanism is proposed in this paper to eliminate these problems. Secondary pressurized double-acting air compressor and two-stage double-acting air compressor based on symmetrical double-crank link mechanism are designed in this paper to increase air compressors output pressure and flow rate and to achieve output control of low pressure high flow and high pressure low flow. It can remove effects generated by lateral force, reduce the vibration and noise and the wearing of cylinder barrel, and improve the steadiness and the service life of the air compressor.
