ABSTRACT:
An exhaust gas recirculator for purification of emission from an internal combustion engine characterized in that an exhaust gas recirculation pipe links the intake manifold and the exhaust pipe connected to the engine cylinder, midway in which is inserted a recirculation control valve acting by the negative pressure of the intake manifold. An orifice with its sectional area variable in the displacement direction of the valve body is provided in the chamber of the recirculation control valve, and a desired flow characteristic of the exhaust gas is obtained by the setting of the orifice configuration.
