Abstract
In a control valve for permitting a valve to open when pressure applied to the valve exceeds a given value so as to escape a given flow rate through a gap defined around the valve, it prevents the valve from floating between a valve seat and a stopper and prevent the valve from striking against the valve seat, the inner surface of a casing and a stopper, thereby preventing the production of noise. The gap defined between the periphery of the valve and a casing is set to be small while the velocity V of the fluid flowing through the gap is increased so as to increase resistance force operating on the valve, whereby the valve always contacts the stopper whenever the valve is opened. There is provided a fluid passage through which fluid passes inside and outside the valve for compensating the flow rate which corresponds to the reduced flow rate caused by the reduction of the gap.
