ABSTRACT:
An exhaust gas recirculator wherein a double diaphragm type flow control valve is disposed in a recirculating passage which couples an exhaust system and an intake or suction system of an internal combustion engine. The flow control valve includes first and second diaphragms, and is formed with a first pressure control chamber partitioned by a first diaphragm and a second pressure control chamber partitioned by the first diaphragm and a second diaphragm. Vacuum is introduced into the first and second pressure control chambers from vacuum ports provided in the vicinity of a throttle valve of a carburetor. Thus, the stroke of a valve shaft of the flow control valve and accordingly the opposing area between a valve body and valve seat of the flow control valve are controlled in two stages, so that the single flow control valve can control the amount of recirculative exhaust gas in two stages.
