れることを特徴とする排気還流制御装置。(1) An exhaust gas recirculation path that branches from the engine intake path and connects to the exhaust path is configured to open and close in response to the negative pressure introduced into the negative pressure chamber, and detects the degree of opening. A reflux control valve equipped with an opening detector is interposed, and the negative pressure chamber is connected to a negative pressure source of the engine via a constant pressure valve,
The negative pressure introduction path connecting the negative pressure chamber and the constant pressure valve is connected to an atmosphere release path provided with a solenoid valve that opens and closes depending on the operating state of the engine and the detected value of the opening detector. In the control device, a first throttle is provided in the negative pressure introduction path between the constant pressure valve and the atmosphere release path, and a second restriction having a larger opening area than the first restriction is provided in the atmosphere release path. Characteristic exhaust recirculation control device.
