Abstract
To provide a fluid control valve capable of providing appropriate responsiveness of the valve member or capable of compensating for fluid shortage in the case of low fluid pressure, by positively controlling the oscillation condition of the valve member according to such conditions as the temperature or pressure of the fluid. The valve includes a valve bodyfor controlling supply of fluid according to a position of a valve member, an electromagnetic driving meansfor displacing a position of the valve memberaccording to an amount of power supplied thereto, and a controlling meansfor controlling the power supply amount to the electromagnetic driving meansby a duty ratio of a pulse-width modulated signal. The controlling meansvaries the pulse width modulated signal so as to vary oscillation amplitude of the valve memberaccording to a condition of at least either one of temperature and pressure of the fluid and then outputs such varied pulse width modulated signal to the electromagnetic driving means
