Latest Patents

One of Kazuhiro Irie's latest patents is a control valve designed for variable displacement compressors. This innovative control valve includes a first valve that regulates the flow rate of refrigerant from a discharge chamber to a control chamber of a compressor. Additionally, it features a second valve that controls the flow rate of refrigerant from the control chamber to a suction chamber. The design incorporates a solenoid that generates a drive force in a first valve closing direction and a second valve opening direction. A biasing member is also included to create a biasing force in the first valve opening direction and a second valve closing direction. Furthermore, a pressure sensing part is integrated to detect pressure in the suction chamber or control chamber, generating a counterforce against the drive force. The system allows for both valves to be open during an increase in current supplied to the solenoid, enhancing the control over the refrigerant flow.
