Screw Compressor Chamber Timing Control for Intermediate Pressure

The patent applies the dynamics principle by making the compression chamber volumes adjustable rather than fixed. The variable displacement mechanism allows the volumes of the first and second compression chambers to be dynamically changed according to operating conditions, enabling the intermediate pressure to be maintained at an ideal value across different operating states, thus preventing performance degradation while maintaining high compression ratios in two-stage mode.

The patent applies the universality principle by designing a variable displacement mechanism that serves multiple functions: it adjusts the volumes of both the first compression chamber and the second compression chamber, controls the intermediate pressure, and enables optimal operation in both single-stage and two-stage modes. This multi-functional approach achieves performance stabilization without requiring separate adjustment mechanisms for each chamber, thereby limiting the increase in device complexity.

The patent applies the dynamics principle by implementing adjustable volume mechanisms for both compression chambers, allowing the volume ratio to be dynamically modified according to operating conditions. This dynamic adjustment capability enables intermediate pressure control without requiring extremely precise fixed manufacturing tolerances, as the system can adapt to variations through operational adjustment rather than relying solely on manufacturing precision.
