Abstract
PURPOSE: To enable to accomplish the metering of main fuel normally by a method wherein a bypass, bypassing the main fuel metering part, is provided so as to be able to discharge vapor bubbles generated in high temperature fuel therefrom.
CONSTITUTION: When the temperature of the fuel in a float chamber 15 turns to be high during engine running, the evaporation of the fuel occurs to generate vapor bubbles in the fuel liquid and the fuel containing bubbles therein flows to a main fuel jet 8. On the other hand, at this time, the negative pressure of the bypass 10 is kept in the state that the fuel in a main fuel passage 9 does not flow in a negaive pressure passage 11 and at the same time the air in an air passage 12 does not flow back to said passage 9 by utilizing the negative pressure at a venturi 6 and properly adjusting the throttles of a negative pressure jet 13 and an air jet 14. As a result, the bubbles in the fuel arrived just before the jet 8 does not long stagnate there in being sucked out through the bypass 10 and the negative pressure passage 11.
