PURPOSE:To organize right ratio of water supply in accordance with engine revolution by preparation of independent watering carburetor separately. CONSTITUTION:Watering carburetor 12 takes in negative pressure from lower portion of throttle valve 8 of the second ventury 6 of carburetor 4 to be used for the gasoline, and drives diaphragm 15 to forward water through nozzle 9 in the quantity set by adjusting screw 13 and spring 14. In this case, at time of idling or speed reduction, the part of throttle valve 8 of the secondar ventury 6 suffers very strong negative pressure, and therefore diaphragm 15 closes valve seat 16 outdoing the power of spring 14. Thus the water supply is suspended preventing water-hammering, engine corrosion and etc. |
