Background

The term air compressor (air compressor) is a main body of an air source device, and is a device for converting mechanical energy of a prime mover (usually an electric motor) into gas pressure energy, and is an air pressure generating device for compressing air. Air compressors commonly used today include piston air compressors, screw air compressors (which are also classified as twin-screw air compressors and single-screw air compressors), centrifugal compressors, and sliding vane and scroll air compressors. Although these air compressors have certain advantages, the exchange of kinetic energy is mostly performed, and electric energy is converted into air energy through mechanical energy, so as to provide a power source suitable for various application fields and various tools. The air compressor machines of the type described above, with their own characteristics and drawbacks, determine many of the characteristics of the piston compressor due to the design principle. For example, the moving parts have high energy consumption, and if the stress is unbalanced, vibration is generated, and the reciprocating inertia force cannot be controlled; if multi-stage compression is needed, the structure is complex; for example, the noise is generated by the friction between the piston and the cylinder wall due to the reciprocating motion of the connecting rod and the crankshaft, and the compressed air is not continuously discharged and has pulsation.

Accordingly, there is a need for an efficient air compression device that addresses one or more of the above problems.
