Multi-Way Disc Valve Flow Regulation to Prevent Pressure Burping

The patent applies preliminary action by providing a bypass flow path that is预先 established and ready to operate. When the valve rotor rotates to change flow paths, the bypass provides a pre-prepared alternative route that immediately accepts the redirected flow, preventing sudden pressure changes and burping. The bypass is designed with appropriate sizing and positioning to ensure it is ready to handle flow transitions before they occur.

The bypass flow path acts as an intermediary element between the different flow circuits. When the valve rotor redirects flow from one circuit to another, the bypass serves as a mediator that absorbs and smooths the transition, preventing direct sudden changes in pressure and flow rate that would cause burping. The bypass intermediate route allows flow to transition gradually rather than abruptly.

The bypass flow path is designed with multi-functionality to serve multiple circuits simultaneously. Rather than requiring separate regulation mechanisms for each flow path, the bypass provides a universal flow route that can handle transitions between multiple different circuits. This universal design simplifies the overall regulation mechanism while maintaining the ability to control multiple thermal fluid circuits.

The patent extracts the complex flow rate regulation function from the valve rotor and separates it into a dedicated bypass mechanism. By taking out the flow transition management from the main valve rotor operation, the bypass can be independently optimized for smooth flow transitions without adding complexity to the primary valve control mechanism. This separation simplifies the overall system while enabling multiple flow paths.
