Introduction: Tetsurou Ikoma is an accomplished inventor based in Kawasaki, Japan, with a focus on air conditioning technology. With a total of three patents to his name, Ikoma has significantly contributed to the field of thermal management solutions through innovative designs and mechanisms that enhance efficiency and reduce noise.

Latest Patents: Tetsurou Ikoma's latest inventions include two notable patents. The first is an Expansion Valve with Noise Suppression, designed for air conditioning systems. This valve incorporates a passage for liquid-phase refrigerant from a reservoir to the valve body and a separate passage for vapor-phase refrigerant after it passes through the evaporator. A valve chamber within the refrigerant passage controls the flow of refrigerant, utilizing a valve member operated by a driving rod that responds to temperature and pressure changes. To decrease bubbles contained in the refrigerant, an orifice is placed between the liquid-phase refrigerant inlet and the valve chamber, with a tapered passage to prevent bubble collapse.

The second patent is for a Thermal Expansion Valve, which operates through a driving member activated by the gas pressure of a heat-sensitive working fluid. The key feature of this design is a diaphragm that holds a critical connection between the working fluid and the driving member. The innovative structure allows precise control of the refrigerant flow while ensuring airtight integrity, thanks to the welding of various components.
