Latest Patents

One of Ashikaga's most significant inventions is a five-way valve that incorporates simultaneous defrosting and heating functions. This five-way valve features a cylindrical valve body, which houses a piston member at one end to define a high-pressure chamber and a first pressure chamber. At the opposite end, a defrosting valve defines a second pressure chamber. The design includes a slider valve member that is coupled to the piston member and is slidably employed within the high-pressure chamber. This chamber receives high-temperature and high-pressure refrigerant from the compressor. An electromagnetic valve connects both the first and second pressure converting chambers to the compressor's inlet. When energized, this valve allows the defrosting valve member to actuate, enabling the high-temperature refrigerant to flow to the outdoor heat exchanger for defrosting while simultaneously heating the indoor atmosphere.
