A capacity control valve that implements an accurate pressure control of a valve body by preventing unwanted pressures from influencing on the valve body and that alters the function of a control chamber such that the pressure within the control chamber to which a control pressure is supplied can quickly be modulated. In the capacity control valve, a valve opening joint portion which is integral with a valve body can rapidly be disengaged from an engagement portion which is integral with a pressure sensing device, hence a quick lifting of the valve body so as to modulate the capacity or pressure in the control chamber. Also equating, exactly or approximately, the seal pressure receiving area of the valve body to the effective pressure receiving area of the pressure sensing device, and further to the pressure receiving area of an action face, or equating, exactly or approximately, the seal pressure receiving area to the pressure receiving area of an action face, yields only a desired pressure to act on the valve body.
