Latest Patents

One of Han-Jun Kim's latest patents is titled "Enhanced flow compressor discharge port entrance." This invention introduces a notch in the motor end bearing of a rotary compressor, specifically in the region of the discharge port. The notch is designed to enhance the flow by smoothing the flow path and guiding the flow to impinge upon the discharge valve in a glancing manner. This innovation effectively reduces noise from the valve and turbulent flow through the discharge port. The notch is strategically located along the axis of the discharge valve and on the side of the valve port where the valve pivots.

Another significant patent is "Noise reduction in a hermetic rotary compressor." This invention addresses the high levels of low-frequency sound generated by compressors. It prevents the formation of reflected waves along the circumference that produce resonant sound modes, thereby reducing the amplification of low-frequency gas pulsations. The design includes muffler outlets positioned at half the wavelength of the reflected waves, which face each other to create a 180-degree phase shift, resulting in destructive interference of the pulsating gas components.
