Synchronous Rotary Compressor Reducing Friction

The patent applies the inversion principle by making both the cylinder block and rotor movable instead of keeping the cylinder block stationary. Specifically, the cylinder block rotates around its own axis while the rotor rotates around a different axis, and both are driven by crank mechanisms. This eliminates the high relative movement speed between stationary and moving parts, reducing friction and abrasion while maintaining structural simplicity.

The patent applies the counterweight principle by designing the cylinder block and rotor with eccentric rotation axes. The cylinder block rotates around an axis offset from its geometric center, and the rotor rotates around a different offset axis. This eccentric design creates balanced inertial forces during rotation, allowing high rotation speeds without excessive vibration, thus improving productivity while maintaining stability.

The patent applies the extraction principle by eliminating traditional wearing parts such as suction valves, discharge valves, and piston rings. Instead, the invention uses the eccentric rotation of the cylinder block and rotor to create natural sealing through the clearance between these components. This removes the wearing parts from the system, improving service life while maintaining adequate sealing performance through the designed clearance geometry.

The patent applies the parameter changes principle by intentionally designing specific clearance parameters between the cylinder block and rotor. Instead of requiring high fabricating precision for tight tolerances, the invention optimizes the clearance dimensions to achieve proper sealing and lubrication. This approach reduces the stringency of manufacturing precision requirements while maintaining performance, thereby simplifying the production process and reducing costs.
