Abstract: Disclosed herein is an exhaust gas recirculation control valve for a diesel engine. The valve comprises a valve casing, disposed in the intake line of the engine, of a rectangular cross sectional shape. A valve seat connected to an exhaust line of the engine via an EGR passageway is formed in a side wall of the rectangular shaped valve casing. A valve member of a plate shape is arranged in the casing and is rotated about an axis located upstream of the valve seat in such a manner that the valve member is moved between a position wherein the plate closes the valve seat and another position wherein the plate closes the intake passageway. The valve device is operated by an actuator means including a vacuum actuator connected to the valve plate and a vacuum generator which transmits a vacuum signal into the actuator in accordance with the load of the engine.
