置。[Claims for Utility Model Registration] This is an exhaust gas recirculation device for a diesel engine, in which a fuel injection pump of the diesel engine controls a fuel injection amount according to atmospheric pressure reflected in a governor mechanism 30 and an atmospheric pressure detection chamber 38. a fuel injection amount altitude compensator 36 for correcting the exhaust gas recirculation device; A negative pressure control valve 76 that controls the negative pressure from the pressure source to a pressure that is approximately inversely proportional to the opening degree of the accelerator lever of the injection pump and outputs it to the negative pressure chamber of the exhaust gas recirculation control valve, A part of the output negative pressure from the negative pressure control valve is introduced into the atmospheric pressure detection chamber 38 of the fuel injection amount altitude compensator, and the governor mechanism 30 of the fuel injection pump is configured as an all-speed type governor mechanism. Features an exhaust gas recirculation device for diesel engines.
