摘要:
An EGR device for an internal combustion engine, including an EGR valve body in an EGR pipe for changing the opening degree of the EGR pipe for regulating the amount of the recirculated exhaust gas, a diaphragm supported by casing of the EGR valve and connected to the EGR valve body for forming a negative pressure chamber, and a solenoid fixed to a sleeve of one of the casing for driving a spool valve in the direction to the diaphragm when the solenoid is excited. The excitation of the solenoid is controlled by a control circuit in accordance with the running conditions of the internal combustion engine.
