Latest Patents

One of Hashiguchi's latest patents is an expansion valve designed for high valve opening adjustment accuracy. This expansion valve features a valve housing with an inlet port for refrigerant from a condenser and an outlet port directing refrigerant toward an evaporator. The valve body is driven by a solenoid and sits on a valve seat, with an urging member that pushes the valve body in a closing direction. A unique space is formed on the valve opening direction side of the valve body, allowing refrigerant to flow into this space, enhancing its operational efficiency.

Another notable patent is a valve that includes a housing with both primary and secondary pressure spaces. This valve features a valve seat positioned between these two spaces and a valve body that moves axially, driven by a source. A communication passage allows for interaction between the back space adjacent to one of the pressure spaces and the other. A partition member ensures that the back space and one of the pressure spaces remain sealed from each other, improving the valve's performance.
