PURPOSE:To feed fuel optimally with correspondence to the altitude and load, by employing a double step atmospheric pressure corrector for carburetor while regulating the correcting amount with correspondence to the load. CONSTITUTION:Under normal travel on high-land, a bellows 21 will push a lever 22 to open a valve 23 properly and since the negative pressure of suction tube 4 is high, a diaphragm 11 is sucked against a spring 11' to open a hole 14 thus to feed correction air through air-cleaner 13, hole 14 and valve 23 to produce mixture gas of proper air fuel ratio. On higher land, the lever 22 will open second valve 5 to feed more air. Under heavy load, droppage of negative pressure of suction tube will cause closure of valve 11 to stop air supply except when the second valve 5 is closed under high-land travel thus to feed concentrated mixture gas. |
