ABSTRACT:
A flow control device comprising an EGR control valve arranged in an EGR passage. The pressure control chamber of the EGR control valve is connected to a pressure control valve in a conduit, and a volume chamber is arranged in the conduit. The vibration of the valve body and the diaphragm of the EGR valve is prevented by the reflecting wave of the pressure wave which is produced in the pressure control chamber due to such vibrations.
