PURPOSE:To make control of a suction control valve according to an engine load in any internal combustion engine regardless of model, type, and fuel supply system by providing a suction port which involves a helical passage and straight passage and increasing the opening of the suction control valve in the straight passage along with increase of the pressure of exhaust gas. CONSTITUTION:When the pressure of exhaust gas is increased in association with increase of the load of an internal combustion engine up to a certain value or higher, a diaphragm 22 is forced downwards against the spring force of a compression coiled spring 24. A valve element 17 is thereby opened, allowing some of mixture to flow via a straight passage 14. |
