Latest Patents

Shirahuji holds a patent for a capacity control valve. This valve implements accurate pressure control of a valve body by preventing unwanted pressures from influencing the valve body. It alters the function of a control chamber, allowing for quick modulation of pressure within the control chamber to which a control pressure is supplied. The design features a valve opening joint portion that can rapidly disengage from an engagement portion integral with a pressure sensing device. This mechanism enables a quick lifting of the valve body, modulating the capacity or pressure in the control chamber effectively. By equating the seal pressure receiving area of the valve body to the effective pressure receiving area of the pressure sensing device, the valve ensures that only the desired pressure acts on the valve body.
