Latest Patents

One of Sugiura’s latest inventions is a variable capacity compressor designed for use in a heat-exchange circuit. This innovative compressor incorporates a pressure responsive valve within a communication passageway that links a low pressure chamber to a pressure controlled chamber. The valve operates based on the pressure within the low pressure chamber, allowing it to open or close the passageway to manage the pressure levels in the controlled chamber. This mechanism enables the compressor to adjust its capacity, reducing it when the pressure drops below a predetermined threshold. Additionally, his invention features an electrically operated control device that maintains a larger capacity independently of the pressure responsive valve, ensuring optimal performance even under varying conditions.

Another significant patent by Sugiura is for an air conditioning system equipped with a variable capacity compressor. This system includes a refrigerating circuit, with the compressor functioning alongside a pressure control valve that adjusts the flow based on the pressure in a high pressure zone. This advance enhances the system's overall efficiency, making it a valuable asset for modern air conditioning solutions.
